Its needs for a long operational life are simple. They are: 1. A suitable operating environment 2. An adequate supply of electricity 3. An adequate flow of cooling water over the motor 4. An appropriate pump load All considerations of application, installation, and maintenance of submersible motors relating to these four areas are presented in this manual. Franklin Electric’s web page, www.franklin-electric.com, should be checked for the latest updates.

During acceleration, the pump thrust increases as its output head increases. In cases where the pump head stays below its normal operating range during startup and full speed condition, the pump may create upward thrust. This creates upward thrust on the motor upthrust bearing. This is an acceptable operation for short periods at each start, but running continuously with upthrust will cause excessive wear on the upthrust bearing. With certain additional restrictions as listed in this section and the Inline Booster Pump Systems sections of this manual, motors are also suitable for operation in positions from shaft-up to shaft-horizontal. As the mounting position becomes further from vertical and closer to horizontal, the probability of shortened thrust bearing life increases. For normal motor life expectancy with motor positions other than shaft-up, follow these recommendations: Franklin Electric submersible motors are a water-lubricated design. The fill solution consists of a mixture of deionized water and Propylene Glycol (a non-toxic antifreeze). The solution will prevent damage from freezing in temperatures to -40 °F (-40 motors should be stored in areas that do not go below this temperature. The solution will partially freeze below 27 °F but no damage occurs. Repeated freezing and thawing should be avoided to prevent possible loss of fill solution. There may be an interchange of fill solution with well water during operation. Care must be taken with motors removed from wells during freezing conditions to prevent damage. When the storage temperature does not exceed 100 °F (37 storage time should be limited to two years. Where temperatures reach 100° to 130 storage time should be limited to one year. Loss of a few drops of liquid will not damage the motor as an excess amount is provided, and the filter check valve will allow lost liquid to be replaced by filtered well water upon installation. If there is reason to believe there has been a considerable amount of leakage, consult the factory for checking procedures. The average number of starts per day over a period of months or years influences the life of a submersible pumping system. Excessive cycling affects the life of control components such as pressure switches, starters, relays, and capacitors. Rapid cycling can also cause motor spline damage, bearing damage, and motor overheating. All these conditions can lead to reduced motor life. The pump size, tank size, and other controls should be selected to keep the starts per day as low as practical for longest life. The maximum number of starts per 24-hour period is shown in Table 3. Motors should run a minimum of one minute to dissipate heat build up from starting current. Six inch and larger motors should have a minimum of 15 minutes between starts or starting attempts. 1. Minimize the frequency of starts, preferably to fewer than per 24-hour period. Six and eight inch motors should have a minimum of 20 minutes between starts or starting attempts 2. Do not use in systems which can run even for short periods at full speed without thrust toward the motor.

However, when used with a properly configured Reduced Voltage Starter (RVS) or Variable Frequency Drive (VFD), 7.5 thru 30 hp three-phase motors can be started up to 200 times per 24 hour period. 3 ---PAGE BREAK--- All Motors APPLICATION Distribution transformers must be adequately sized to satisfy the kVA requirements of the submersible motor. When transformers are too small to supply the load, there is a reduction in voltage to the motor. Table 4 references the motor horsepower rating, single-phase and three-phase, total effective kVA required, and the smallest transformer required for open or closed Transformer Capacity - Single-Phase or Three-Phase NOTE: Standard kVA ratings are shown. If power company experience and practice allows transformer loading higher than standard, higher loading values may be used to meet total effective kVA required, provided correct voltage and balance is maintained. three-phase systems. Open systems require larger transformers since only two transformers are used. Other loads would add directly to the kVA sizing requirements of the transformer bank. During starting of a submersible pump, the torque developed by the motor must be supported through the pump, delivery pipe or other supports. Most pumps rotate in the direction which causes unscrewing torque on right-handed threaded pipe or pump stages. All threaded joints, pumps and other parts of the pump support system must be capable of withstanding the maximum torque repeatedly without loosening or breaking. Unscrewing joints will break electrical cable and may cause loss of the pump-motor unit. To safely withstand maximum unscrewing torques with a minimum safety factor of 1.5, tightening all threaded joints to at least 10 lb-ft per motor horsepower is recommended (Table 4A). It may be necessary to tack or strap weld pipe joints on high horsepower pumps, especially at shallower settings.

Contact power company for use and approval. Table 5 lists minimum generator sizes based on typical 80 °C rise continuous duty generators, with 35% maximum voltage dip during starting, for Franklin’s three-wire motors, single- or three-phase. This is a general chart. The generator manufacturer should be consulted whenever possible, especially on larger sizes. There are two types of generators available: externally and internally regulated. Most are externally regulated. They use an external voltage regulator that senses the output voltage. As the voltage dips at motor start-up, the regulator increases the output voltage of the generator. Internally regulated (self-excited) generators have an extra winding in the generator stator. The extra winding senses the output current to automatically adjust the output voltage. Generators must be sized to deliver at least 65% of the rated voltage during starting to ensure adequate starting torque. Besides sizing, generator frequency is important as the motor speed varies with the frequency (Hz). Due to pump affinity laws, a pump running at 1 to 2 Hz below motor nameplate frequency design will not meet its performance curve. Conversely, a pump running at 1 to 2 Hz above may trip overloads. Generator Operation Always start the generator before the motor is started and always stop the motor before the generator is shut down. The motor thrust bearing may be damaged if the generator is allowed to coast down with the motor running. This same condition occurs when the generator is allowed to run out of fuel. Follow generator manufacturer’s recommendations for de-rating at higher elevations or using natural gas. It is recommended that one or more check valves always be used in submersible pump installations. If the pump does not have a built-in check valve, a line check valve should be installed in the discharge line within 25 feet of the pump and below the draw down level of the water supply. For deeper settings, check valves should be installed per the manufacturer’s recommendations. More than one check valve may be required, but more than the recommended number of check valves should not be used. Swing type check valves are not acceptable and should never be used with submersible motors/pumps. Swing type check valves have a slower reaction time which can cause water hammer (see next page). Internal pump check valves or spring loaded check valves close quickly and help eliminate water hammer. Check valves are used to hold pressure in the system when the pump stops. They also prevent backspin, water hammer and upthrust. Any of these can lead to early pump or motor failure. NOTE: Only positive sealing check valves should be used in submersible installations. Although drilling the check valves or using drain-back check valves may prevent back spinning, they create upthrust and water hammer problems. A. Backspin - With no check valve or a failed check valve, the water in the drop pipe and the water in the system can flow down the discharge pipe when the motor stops. This can cause the pump to rotate in a reverse direction. If the motor is started while it is backspinning, an excessive force is placed across the pump- motor assembly that can cause impeller damage, motor or pump shaft breakage, excessive bearing wear, etc. B. Upthrust - With no check valve, a leaking check valve, or drilled check valve, the unit starts under a zero head condition. This causes an uplifting or upthrust on the impeller-shaft assembly in the pump. This upward movement carries across the pump-motor coupling and creates an upthrust condition in the motor. Repeated upthrust can cause premature failure of both the pump and the motor. C. Water Hammer - If the lowest check valve is more than 30 feet above the standing (lowest static) water level, or a lower check valve leaks and the check valve above holds, a vacuum is created in the discharge piping. On the next pump start, water moving at very high velocity fills the void and strikes the closed check valve and the stationary water in the pipe above it, causing a hydraulic shock. This shock can split pipes, break joints and damage the pump and/or motor. Water hammer can often be heard or felt. When discovered, the system should be shut down and the pump installer contacted to correct the problem.

For best starting of 2-wire motors, the minimum generator rating is 50% higher than shown. 5 ---PAGE BREAK--- All Motors APPLICATION Franklin Electric submersible motors are designed to operate with a cooling flow of water over and around the full length of the motor. If the pump installation does not provide the minimum flow shown in Table 6, a flow inducer sleeve (flow sleeve) must be used. The conditions requiring a flow sleeve are: Wells – Large Diameter, Uncased, Top Feeding and Screened Sections • Well diameter is too large to meet Table 6 flow requirements • Pump is in an open body of water • Pump is in a rock well or below the well casing • The well is “top-feeding” (a.k.a. cascading) • Pump is set in or below screens or perforations Franklin Electric’s standard submersible motors, except Hi-Temp designs (see note below), are designed to operate up to maximum service factor horsepower in water up to 86 °F (30 A flow of 0.25 ft/s for 4" motors rated 3 hp and higher, and 0.5 ft/s for 6" and 8" motors is required for proper cooling. Table 6 shows minimum flow rates, in gpm, for various well diameters and motor sizes. If a standard motor is operated in water over 86 °F (30 water flow past the motor must be increased to maintain safe motor operating temperatures. See HOT WATER APPLICATIONS on page 7. NOTE: Franklin Electric offers a line of Hi-Temp motors designed to operate in water at higher temperatures or lower flow conditions. Consult factory for details. Water Temperature and Flow 0.25 ft/s = 7.62 cm/sec 0.50 ft/s = 15.24 cm/sec 1 inch = 2.54 cm If the flow rate is less than specified, then a flow inducer sleeve must be used. A flow sleeve is always required in an open body of water. FIG. 1 shows a typical flow inducer sleeve construction. EXAMPLE: A 6" motor and pump that delivers 60 gpm will be installed in a 10" well. From Table 6, 90 gpm would be required to maintain proper cooling. In this case adding an 8" or smaller flow sleeve provides the required cooling.

When a standard pump-motor operates in water hotter than 86 °F (30 a flow rate of at least 3 ft/s is required. When selecting the motor to drive a pump in over 86 °F (30 water, the motor horsepower must be de-rated per the following procedure. 1. Using Table 7A, determine pump gpm required for different well or sleeve diameters. If necessary, add a flow sleeve to obtain at least 3 ft/s flow rate.

It is done to limit the voltage between nonelectrical (exposed metal) parts of the system and ground, thus minimizing dangerous shock hazards. Using wire at least the size of the motor cable wires provides adequate current-carrying capability for any ground fault that might occur. It also provides a low resistance path to ground, ensuring that the current to ground will be large enough to trip any overcurrent device designed to detect faults (such as a ground fault circuit interrupter, or GFCI). Normally, the ground wire to the motor would provide the primary path back to the power supply ground for any ground fault. There are conditions, however, where the ground wire connection could become compromised. One such example would be the case where the water in the well is abnormally corrosive or aggressive. In this example, a grounded metal drop pipe or casing would then become the primary path to ground. Franklin Electric control boxes, Pumptec products and three-phase panels meet UL requirements for NEMA Type 3R enclosures. They are suitable for indoor and outdoor applications within temperatures of +14 °F (-10 to 122 °F (50 Operating control boxes below +14 °F can cause reduced starting torque and loss of overload protection when overloads are located in control boxes. Control boxes, Pumptec products, and three-phase panels should never be mounted in direct sunlight or high temperature locations. This will cause shortened capacitor life (where applicable) and unnecessary tripping of overload protectors. A ventilated Control Box, Pumptec Products, and Panel Environment enclosure painted white to reflect heat is recommended for an outdoor, high temperature location. A damp well pit, or other humid location, accelerates component failure from corrosion. Control boxes with voltage relays are designed for vertical upright mounting only. Mounting in other positions will affect the operation of the relay. Allowable motor temperature is based on atmospheric pressure or higher surrounding the motor. “Drawdown seals,” which seal the well to the pump above its intake to Grounding Surge Arrestors An above ground surge arrestor must be grounded, metal to metal, all the way to the lowest draw down water strata for the surge arrestor to be effective. GROUNDING THE ARRESTOR TO THE SUPPLY GROUND OR TO A DRIVEN GROUND ROD PROVIDES LITTLE OR NO SURGE PROTECTION FOR THE MOTOR. maximize delivery are not recommended, since the suction created can be lower than atmospheric pressure. Equipment Grounding However, the many installations that now use plastic drop pipes and/or casings require further steps to be taken for safety purposes, so that the water column itself does not become the conductive path to ground. When an installation has abnormally corrosive water AND the drop pipe or casing is plastic, Franklin Electric recommends the use of a GFCI with a 10 mA set-point. In this case, the motor ground wire should be routed through the current-sensing device along with the motor power leads. Wired this way, the GFCI will trip only when a ground fault has occurred AND the motor ground wire is no longer functional. WARNING: Serious or fatal electrical shock may result from failure to connect the motor, control enclosures, metal plumbing, and all other metal near the motor or cable to the power supply ground terminal using wire no smaller than motor cable wires. WARNING: Failure to ground the control frame can result in a serious or fatal electrical shock hazard. The National Electrical Code requires that the control box or panel-grounding terminal always be connected to supply ground. If the circuit has no grounding conductor and no metal conduit from the box to supply panel, use a wire at least as large as line conductors and connect as required by the National Electrical Code, from the grounding terminal to the electrical supply ground. Drawdown Seals Grounding Control Boxes and Panels 9 ---PAGE BREAK--- Single-Phase Motors APPLICATION BIAC Switch Operation When power is applied the bi-metal switch contacts are closed, so the triac is conducting and energizes the start winding. As rpm increases, the voltage in the sensor coil generates heat in the bi-metal strip, causing the bi-metal strip to bend and open the switch circuit. This removes the starting winding and the motor continues to run on the main winding alone. Approximately 5 seconds after power is removed from the motor, the bi-metal strip cools sufficiently to return to its closed position and the motor is ready for the next start cycle. If, during operation, the motor speed drops, the lowered voltage in the sensor coil allows the bi-metal contacts to close, and bring the motor back to operating speed. Rapid Cycling The BIAC starting switch will reset within approximately 5 seconds after the motor is stopped. If an attempt is made to restart the motor before the starting switch has reset, the motor may not start; however, there will be current in the main winding until the overload protector interrupts the circuit. The time for the protector to reset is longer 2-Wire Motor Solid State Controls than the reset of the starting switch. Therefore, the start switch will have closed and the motor will operate. A waterlogged tank will cause fast cycling. When a waterlogged condition does occur, the user will be alerted to the problem during the off time (overload reset time) since the pressure will drop drastically. When the waterlogged tank condition is detected, the condition should be corrected to prevent nuisance tripping of the overload protector. Bound Pump (Sandlocked) When the motor is not free to turn, as with a sandlocked pump, the BIAC switch creates a “reverse impact torque” in the motor in either direction. When the sand is dislodged, the motor will start and operate in the correct direction. There are two elements in the relay: a reed switch and a triac. The reed switch consists of two tiny rectangular blade-type contacts, which bend under magnetic flux. It is hermetically sealed in glass and is located within a coil, which conducts line current. When power is supplied to the control box, the main winding current passing through the coil immediately closes the reed switch contacts. This turns on the triac, which supplies voltage to the start winding, thus starting the motor. Once the motor is started, the operation of the QD relay is an interaction between the triac, the reed switch, and the motor windings. The solid state switch senses motor speed through the changing phase relationship between start winding current and line current. As the motor approaches running speed, the phase angle between the start current and the line current becomes nearly in phase. At this point, the reed switch contacts open, turning off the triac. This removes voltage from the start winding and the motor continues to run on the main winding only. With the reed switch contacts open and the triac turned off, the QD relay is ready for the next starting cycle. Single-phase three-wire submersible motors require the use of control boxes. Operation of motors without control boxes or with incorrect boxes can result in motor failure and voids warranty. Control boxes contain starting capacitors, a starting relay, and, in some sizes, overload protectors, running capacitors, and contactors. Ratings through 1 hp may use either a Franklin Electric solid state QD or a potential (voltage) type starting relay, while larger ratings use potential relays. Potential (Voltage) Relays Potential relays have normally closed contacts. When power is applied, both start and main motor windings are energized, and the motor starts. At this instant, the voltage across the start winding is relatively low and not enough to open the contacts of the relay. 3-Wire Control Boxes CAUTION: The control box and motor are two pieces of one assembly. Be certain that the control box and motor hp and voltage match. Since a motor is designed to operate with a control box from the same manufacturer, we can promise warranty coverage only when a Franklin control box is used with a Franklin motor. CAUTION: Restarting the motor within 5 seconds after power is removed may cause the motor overload to trip. QD Relays (Solid State) 10 As the motor accelerates, the increasing voltage across the start winding (and the relay coil) opens the relay contacts. This opens the starting circuit and the motor continues to run on the main winding alone, or the main plus run capacitor circuit. After the motor is started the relay contacts remain open. ---PAGE BREAK--- Single-Phase Motors APPLICATION 75 °C 2- or 3-Wire Cable, 60 Hz (Service Entrance to Motor - Maximum Length In Feet) in BOLD only meet the US National Electrical Code ampacity requirements for individual conductors 60 °C or 75 °C in free air or water, not in magnetic enclosures, conduit or direct buried. NOT in bold meet the NEC ampacity requirements for either individual conductors or jacketed 60 °C or 75 °C cable and can be in conduit or direct buried. Flat molded and web/ribbon cable are considered jacketed cable. If any other cable is used, the NEC and local codes should be observed. Cable in Tables 11 & 11A allow for a 5% voltage drop running at maximum nameplate amperes. If 3% voltage drop is desired, multiply Table 11 and 11A by 0.6 to get maximum cable length. The portion of the total cable length, which is between the supply and single-phase control box with a line contactor, should not exceed 25% of total maximum allowable to ensure reliable contactor operation. Single-phase control boxes without line contactors may be connected at any point in the total cable length. Tables 11 & 11A are based on copper wire. If aluminum wire is used, it must be two sizes larger than copper wire and oxidation inhibitors must be used on connections. EXAMPLE: If Tables 11 & 11A call for #12 copper wire, #10 aluminum wire would be required.

For example, in a replacement/upgrade installation, the well already has 160 feet of buried #10 cable between the service entrance and the wellhead. A new 3 hp, 230-volt, single-phase motor is being installed to replace a smaller motor. The question is: Since there is already 160 feet of #10 AWG installed, what size cable is required in the well with a 3 hp, 230-volt, single-phase motor setting at 310 feet? From Tables 11 & 11A, a 3 hp motor can use up to 300 feet of #10 AWG cable. The application has 160 feet of #10 AWG copper wire installed. Using the formula below, 160 feet (actual) ÷ 300 feet (max allowable) is equal to 0.533. This means 53.3% (0.533 x 100) of the allowable voltage drop or loss, which is allowed between the service entrance and the motor, occurs in this wire. This leaves us 46.7% (1.00 - 0.533 = 0.467) of some other wire size to use in the remaining 310 feet “down hole” wire run. The table shows #8 AWG copper wire is good for 470 feet. Using the formula again, 310 feet (used) ÷ 470 feet (allowed) = 0.660; adding this to the 0.533 determined earlier; 0.533 + 0.660 = 1.193. This combination is greater than 1.00, so the voltage drop will not meet US National Electrical Code recommendations. Tables 11 & 11A show #6 AWG copper wire is good for 750 feet. Using the formula, 310 ÷ 750 = 0.413, and using these numbers, 0.533 + 0.413 = 0.946, we find this is less than 1.00 and will meet the NEC recommended voltage drop. This works for two, three or more combinations of wire and it does not matter which size wire comes first in the installation.

They may also be used to lower voltage when the available power supply voltage is too high. When the available power supply voltage is not within the proper range, a buck-boost transformer is often used to adjust voltage to match the motor. The most common usage on submersible motors is boosting a 208 volt supply to use a standard 230 volt single-phase submersible motor and control. While tables to give a wide range of voltage boost or buck are published by transformer manufacturers, the following table shows Franklin’s recommendations. The table, based on boosting the voltage 10%, shows the minimum rated transformer kVA needed and the common standard transformer kVA. Do not add running capacitors to 1/3 through 1 hp control boxes, which use solid state switches or QD relays. Adding capacitors will cause switch failure. If the control box is converted to use a voltage relay, the specified running capacitance can be added.

If a motor is overloaded with normal capacitance, it will still be overloaded with auxiliary run capacitance, even though motor amps may be within nameplate values. 15 ---PAGE BREAK--- Three-Phase Motors APPLICATION Continued on next page 60 °C MOTOR RATING 60 °C INSULATION - AWG COPPER WIRE SIZE MCM COPPER WIRE SIZE VOLTS HP KW 14 12 10 8 6 4 3 2 1 0 00 000 0000 250 300 350 400 500 200 V 60 Hz Three- Phase 3 - Lead 1/2 0.37 710 1140 1800 2840 4420 3/4 0.55 [PHONE REDACTED] 2030 3160 1 0.75 [PHONE REDACTED] 1710 2670 4140 5140 1.5 1.1 310 [PHONE REDACTED] 1960 3050 3780 2 1.5 240 390 [PHONE REDACTED] 2360 2940 3610 4430 5420 3 2.2 180 290 [PHONE REDACTED] 1810 2250 2760 3390 4130 5 3.7 110 170 280 [PHONE REDACTED] 1350 1660 2040 2490 3050 3670 4440 5030 7.5 5.5 0 0 200 310 490 [PHONE REDACTED] 1450 1770 2170 2600 3150 3560 10 7.5 0 0 0 230 370 570 [PHONE REDACTED] 1330 1640 1970 2390 2720 3100 3480 3800 4420 15 11 0 0 0 160 250 390 490 600 [PHONE REDACTED] 1340 1630 1850 2100 2350 2570 2980 20 15 0 0 0 0 190 300 380 460 570 [PHONE REDACTED] 1270 1440 1650 1850 2020 2360 25 18.5 0 0 0 0 0 240 300 370 460 570 [PHONE REDACTED] 1170 1330 1500 1640 1900 30 22 0 0 0 0 0 0 250 310 380 470 580 700 [PHONE REDACTED] 1250 1360 1590 230 V 60 Hz Three- Phase 3 - Lead 1/2 0.37 930 1490 2350 3700 5760 8910 3/4 0.55 670 1080 1700 2580 4190 6490 8060 9860 1 0.75 [PHONE REDACTED] 2260 3520 5460 6780 8290 1.5 1.1 [PHONE REDACTED] 1670 2610 4050 5030 6160 7530 9170 2 1.5 320 [PHONE REDACTED] 2010 3130 3890 4770 5860 7170 8780 3 2.2 240 390 [PHONE REDACTED] 2400 2980 3660 4480 5470 6690 8020 9680 5 3.7 140 230 370 [PHONE REDACTED] 1790 2190 2690 3290 4030 4850 5870 6650 7560 8460 9220 7.5 5.5 0 160 260 [PHONE REDACTED] 1270 1560 1920 2340 2870 3440 4160 4710 5340 5970 6500 7510 10 7.5 0 0 190 310 490 [PHONE REDACTED] 1440 1760 2160 2610 3160 3590 4100 4600 5020 5840 15 11 0 0 0 210 330 520 650 [PHONE REDACTED] 1470 1780 2150 2440 2780 3110 3400 3940 20 15 0 0 0 0 250 400 500 610 [PHONE REDACTED] 1380 1680 1910 2180 2450 2680 3120 25 18.5 0 0 0 0 0 320 400 500 610 [PHONE REDACTED] 1360 1540 1760 1980 2160 2520 30 22 0 0 0 0 0 260 330 410 510 620 [PHONE REDACTED] 1280 1470 1650 1800 2110 380 V 60 Hz Three- Phase 3 - Lead 1/2 0.37 2690 4290 6730 3/4 0.55 2000 3190 5010 7860 1 0.75 1620 2580 4060 6390 9980 1.5 1.1 1230 1970 3100 4890 7630 2 1.5 870 1390 2180 3450 5400 8380 3 2.2 680 1090 1710 2690 4200 6500 8020 9830 5 3.7 [PHONE REDACTED] 1590 2490 3870 4780 5870 7230 8830 7.5 5.5 270 [PHONE REDACTED] 1710 2640 3260 4000 4930 6010 7290 8780 10 7.5 200 320 [PHONE REDACTED] 1930 2380 2910 3570 4330 5230 6260 7390 8280 9340 15 11 0 0 370 [PHONE REDACTED] 1770 2170 2690 3290 4000 4840 5770 6520 7430 8250 8990 20 15 0 0 0 [PHONE REDACTED] 1350 1670 2060 2530 3090 3760 4500 5110 5840 6510 7120 8190 25 18.5 0 0 0 360 [PHONE REDACTED] 1350 1670 2050 2510 3040 3640 4130 4720 5250 5740 6590 30 22 0 0 0 0 470 [PHONE REDACTED] 1380 1700 2080 2520 3020 3430 3920 4360 4770 5490 40 30 0 0 0 0 0 530 [PHONE REDACTED] 1240 1520 1840 2200 2500 2850 3170 3470 3990 50 37 0 0 0 0 0 0 540 [PHONE REDACTED] 1220 1480 1770 2010 2290 2550 2780 3190 60 45 0 0 0 0 0 0 0 560 [PHONE REDACTED] 1250 1500 1700 1940 2150 2350 2700 75 55 0 0 0 0 0 0 0 0 570 [PHONE REDACTED] 1270 1440 1660 1850 2030 2350 100 75 0 0 0 0 0 0 0 0 0 510 630 [PHONE REDACTED] 1180 1310 1430 1650 125 93 0 0 0 0 0 0 0 0 0 0 0 620 740 [PHONE REDACTED] 1160 1330 150 110 0 0 0 0 0 0 0 0 0 0 0 0 620 700 790 [PHONE REDACTED] 175 130 0 0 0 0 0 0 0 0 0 0 0 0 0 650 750 [PHONE REDACTED] 200 150 0 0 0 0 0 0 0 0 0 0 0 0 0 0 630 700 760 880 in BOLD only meet the US National Electrical Code ampacity requirements for individual conductors in free air or water.

If the motor is locked, the overload protection must trip within 10 seconds to protect the motor windings. Subtrol/ SubMonitor, a Franklin-approved adjustable overload relay, or a Franklin-approved fixed heater must be used. Fixed heater overloads must be the ambient-compensated quick-trip type to maintain protection at high and low air temperatures. All heaters and amp settings shown are based on total line amps. When determining amperage settings or making heater selections for a six-lead motor with a Wye-Delta starter, divide motor amps by 1.732. Pages 29, 30 and 31 list the correct selection and settings for some manufacturers. Approval for other manufacturers’ types not listed may be requested by calling Franklin’s Technical Service Hotline at [PHONE REDACTED]. Refer to notes on page 30.

Heaters were selected from Catalog 294, table 332 and table 632 (starter size 00, size Size 4 starters are heater type 4 (JG). Starters using these heater tables include classes 14, 17, and 18 (inNOVA), classes 36 and 37 (reduced voltage), and classes 87, 88, and 89 (pump and motor control centers). Overload relay adjustments should be set no higher than 100% unless necessary to stop nuisance tripping with measured amps in all lines below nameplate maximum. Heater selections for class 16 starters (Magnetic Definite Purpose) will be furnished upon request. NOTE 2: General Electric heaters are type CR123 usable only on type CR124 overload relays and were selected from Catalog GEP- 126OJ, page 184. Adjustment should be set no higher than 100%, unless necessary to stop nuisance tripping with measured amps in all lines below nameplate maximum. NOTE 3: Adjustable overload relay amp settings apply to approved types listed. Relay adjustment should be set at the specified SET amps. Only if tripping occurs with amps in all lines measured to be within nameplate maximum amps should the setting be increased, not to exceed the MAX value shown.

(On large motors, this usually requires a motor coupling with a cheater handle welded to it.) 1.3 Check that the motor lead assembly is not damaged. 1.4 Measure insulation resistance to ground at 500 volts – BEFORE SUBMERGED. It should be a minimum of 200 megohms or 200,000,000 ohms. 1.5 Measure insulation resistance to ground at 500 volts – AFTER SUBMERGED. It should be a minimum of 0.5 megohms or 500,000 ohms. 1.6 Verify the system is operating within the ±10% of nameplate voltage requirement. 1.7 Verify the system will not ever operate in excess of the maximum amps indicated on the nameplate. 1.8 Verify the system is operating at 5% or less current unbalance. Notice: • If current unbalance exceeds the maximum operating amps must be derated to the nameplate Full Load Amps. • Warning - System current unbalance can not exceed 10% without causing heating and mechanical wear issues. • The submersible motor amperage % unbalance is typically 6x greater than its voltage % unbalance. • Thus, 0.8% voltage unbalance = greater than 5% current unbalance, and 1.7% voltage unbalance = greater than 10% current unbalance. 2.0 PUMP 2.1 Verify the pump nameplate and curve data meets the application hp, rpm, and flow/TDH requirements. 2.2 Verify the pump NPSH requirement will be met at all times. 2.3 Check that the pump shaft rotates freely by hand before installation. 2.4 Check that the pump shaft moves up about ¼ inch when it is coupled to the motor. 2.5 Check that the pump guard is not pinching the motor leads, especially where it enters and exits the guard. Notice: • Pumps and motors 5 hp and above should be assembled in a vertical position to ensure correct alignment. • A motor-pump assembly 5 hp and above should never be lifted from a non-vertical position by the pump discharge because it can bend the shaft in one or both of the products. 3.0 POWER SUPPLY (3-PHASE) 3.1 Verify the transformer kVA rating is adequate for the motor per the Franklin Application (AIM) manual requirement. 3.2 Verify that all transformers have the same kVA rating. 3.3 Verify the 3-Ph pump panel fuses or its circuit breaker are correctly sized per the Franklin Application (AIM) manual requirement. 3.4 Verify the 3-Ph pump panel motor contactor is correctly sized per the Franklin Application (AIM) manual requirement. 3.5 Verify the 3-Ph pump panel motor overload is ambient compensated. 3.6 Verify the 3-Ph pump panel motor overload has a NEMA Class 10 trip curve. 3.7 Verify the 3-Ph pump panel motor overload heaters or its dial setting are correctly selected based on the system’s operating point and not just arbitrarily set at the maximum motor operating amps. 3.8 At no time should the system operating amps or the motor overload system running point setting be higher than the motor nameplate maximum amp rating. Notice: • Electronic overloads should be set at the normal system operation point. • Electronic overloads have a built-in multiplier of 115-125% times the input amps to determine the overload trip point. 4.0 POWER SUPPLY (1-PHASE) 4.1 Verify the transformer kVA rating is adequate for the motor per the Franklin Application (AIM) manual requirement. ---PAGE BREAK--- Form 2207 - Action Facts SUBMERSIBLE MOTORS INSTALLATION RECORD 4.2 Verify the motor control box and the motor are made by the same manufacturer. 4.3 Verify the motor control box hp rating and its voltage match the motor rating exactly. If not, a premature failure of the control box or motor should be expected. 5.0 HIGH SURGE PROTECTION 5.1 Verify the submersible motor has a dedicated surge arrestor. All submersible motors require a dedicated surge arrestor. Motors 5 hp and smaller marked “Equipped with Lightning Arrestors”, have a built-in surge arrestor. 5.2 Verify the surge arrestor is mounted as close to the motor as practical. The location is usually in the pump panel, but sometimes it is placed at the well head in a separate electrical box. 5.3 Verify the surge arrestor is grounded below the lowest drawdown water level. This is usually accomplished by attaching the drop cable ground wire to the motor lead or the motor ground lug. 5.4 Verify the ground conductor size meets the minimum requirements of the National Electric Code and all other relevant national, state, regional and local codes. 5.5 Verify the motor is connected to both the electrical system ground and the motor. 6.0 ELECTRICAL DROP CABLE 6.1 Verify the temperature rating of the drop cable – typically 60 75 90 °C or 125 6.2 Verify if the cable is single conductor or jacketed conductor. Web cable is considered jacketed cable by regulating agencies. 6.3 Verify the conductor size – typically AWG, MCM or mm2. 6.4 Verify if the conductor material is copper; if not, determine the material and contact the factory for acceptability. 6.5 Verify the drop cable meets or exceeds the requirements of the Franklin Application (AIM) manual. Notice: • If the service entrance to pump panel or the pump panel to motor cable is not a copper material, contact the factory for the correct length derating factors. 7.0 MOTOR COOLING 7.1 Verify that the well water temperature does not exceed the maximum ambient temperature indicated on the nameplate of the motor. 7.2 Verify there is a minimum of 10 feet of clear water between the bottom of the motor and the bottom of the well. 7.3 Verify that all water entering the well is coming from below the lowest part of the motor. 7.4 Verify the system pumping rate will never deliver less flow than is required by the Franklin Application (AIM) manual to flow by-and-around the full length of the motor for cooling purposes. 7.5 Verify that 3-phase motors above 7.5 hp in a vertical potable water well should not exceed 100 starts in 24 hours and each start should include a minimum of 3 minutes ON and 10 minutes OFF. Notice: • If any water is entering the well above the lowest part of the motor, a flow sleeve is required. 8.0 MOTOR-PUMP INSTALLATION 8.1 Verify that the drop cable is supported to the drop pipe every 10 feet. 8.2 Verify at least one spring loaded (non-drilled) check valve is in the drop pipe. Preferably, the first check valve should be located at the top of the first pipe joint above the pump discharge (~20 feet) if the pump does not have a check built in to its discharge. 8.3 Verify all pipe joints are as tight as practical. The minimum torque should never be less than 10 foot-pounds times the motor nameplate hp rating. 8.4 Verify the rotation of the pump is correct. It is preferable to do this by checking the flow and current in both directions on 3-phase motors. This can be done by having the electrician swap any two leads. This is considered “best practice” since pumps under some conditions can supply amp readings and a visual flow observation that can be extremely misleading. ---PAGE BREAK--- RMA Number DISTRIBUTOR INSTALLER END USER Name: City: _ State: Zip: Name: City: _ State: Zip: Name: City: _ State: Zip: Well ID or Water Temperature:_ Application/Water Use (e.g. potable water, irrigation, municipal, fountain, etc.): Date Installed (mm/yy): Date Failed Motor Position Shaft-Up: *Yes *No Operating Cycle: ON Time Per Start *Hrs. *Mins.

Booster Installation Record SUBMERSIBLE MOTOR ---PAGE BREAK--- Three-Phase Motors APPLICATION Applications SubMonitor is designed to protect 3-phase pumps/motors with service factor amp ratings (SFA) from 5 to 350 A (approx. 3 to 200 hp). Current, voltage, and motor temperature are monitored using all three legs and allows the user to set up the SubMonitor quickly and easily. Protects Against • Under/Overload • Under/Overvoltage • Current Unbalance • Overheated Motor (if equipped with Subtrol Heat Sensor) • False Start (Chattering) • Phase Reversal In some installations, power supply limitations make it necessary or desirable to increase the power factor of a submersible motor. Table 32 lists the capacitive kVAR required to increase the power factor of large Franklin three-phase submersible motors to the approximate values shown at maximum input loading.

CONTACTS PRESSURE SWITCH OR OTHER CONTROL DEVICE L1 L2 L3 FUSES CONTACTS OVERLOAD HEATER AND/OR MOTOR COIL TO SEPARATE CONTROL VOLTAGE SOURCE SUBTROL DEVICE Three-phase combination magnetic starters have two distinct circuits: a power circuit and a control circuit. The power circuit consists of a circuit breaker or fused line switch, contacts, and overload heaters connecting incoming power lines L1, L2, L3 and the three-phase motor. The control circuit consists of the magnetic coil, overload contacts, and a control device External Voltage Controls Control of a power circuit by a lower circuit voltage can also be obtained by connecting to a separate control voltage source. The coil rating must match the control voltage source, such as 115 or 24 volts. such as a pressure switch. When the control device contacts are closed, current flows through the magnetic contactor coil, the contacts close, and power is applied to the motor. Hand-Off-Auto switches, start timers, level controls, and other control devices may also be in series in the control circuit. Line Voltage Control This is the most common type of control encountered. Since the coil is connected directly across the power lines L1 and L2, the coil must match the line voltage. Low Voltage Transformer Control This control is used when it is desirable to operate push buttons or other control devices at some voltage lower than the motor voltage. The transformer primary must match the line voltage and the coil voltage must match the secondary voltage of the transformer. FIG. 4 FIG. 5 FIG. 6 Three-Phase Starter Diagrams 33 ---PAGE BREAK--- Three-Phase Motors APPLICATION A full three-phase supply is recommended for all three-phase motors, consisting of three individual transformers or one three-phase transformer. So-called “open” Delta or Wye connections using only two transformers can be used, but are more likely to cause problems, such as poor performance, overload tripping or early motor failure due to current unbalance. Transformer rating should be no smaller than listed in Table 4 for supply power to the motor alone. 1. Establish correct motor rotation by running the motor in both directions. Normal rotation is CCW viewing the shaft end. Rotation can be changed by interchanging any two of the three motor leads. The rotation that gives the most water flow is typically the correct rotation. 2. After correct rotation has been established, check the current in each of the three motor leads and calculate the current unbalance as explained in 3 below. If the current unbalance is 2% or less, leave the leads as connected. If the current unbalance is more than current readings should be checked on each leg using each of three possible hook-ups. Roll the motor leads across the starter in the same direction to prevent motor reversal. 3. To calculate percent of current unbalance: A. Add the three line amps values together B. Divide the sum by three, yielding average current C. Pick the amp value which is furthest from the average current (either high or low) D. Determine the difference between this amp value(furthest from average) and the average E. Divide the difference by the average. Multiply the result by 100 to determine percent of unbalance Checking and Correcting Rotation and Current Unbalance T2 T1 T3 L1 L2 L3 T1 T3 T2 L1 L2 L3 T3 T2 T1 L1 L2 L3 1st Hook Up 2nd Hook Up 3rd Hook Up supply starter motor FIG. 7 FULL THREE-PHASE FIG. 8 OPEN DELTA 1 50 = 0.02 or 2% EXAMPLE: T1 = 51 amps T3 = 50 amps T2 = 50 amps T2 = 46 amps T1 = 49 amps T3 = 48 amps T3 = 53 amps T2 = 51 amps T1 = 52 amps Total = 150 amps Total = 150 amps Total = 150 amps + + + 50 - 46 = 4 amps 50 - 49 = 1 amp 50 - 48 = 2 amps 2 50 = 0.04 or 4% 150 3 = 50 amps 150 3 = 50 amps 4 50 = 0.08 or 8% 150 3 = 50 amps Three-Phase Power Unbalance 34 4. Current unbalance should not exceed 5% at max amp load or 10% at rated input load. If the unbalance cannot be corrected by rolling leads, the source of the unbalance must be located and corrected. If, on the three possible hookups, the leg farthest from the average stays on the same power lead, most of the unbalance is coming from the “power side” of the system. If the reading farthest from average moves with the same motor lead, the primary source of unbalance is on the “motor side” of the starter. In this instance, consider a damaged cable, leaking splice, poor connection, or faulty motor winding. Phase designation of leads for CCW rotation viewing shaft end.

WYE-DELTA starters connect the motor as shown below during starting, then change to the running connection shown at the left. There are a number of different types of phase converters available. Each generates three-phase power from a single-phase power line. In all phase converters, the voltage balance is critical to current balance. Although some phase converters may be well balanced at one point on the system-operating curve, submersible pumping systems often operate at differing points on the curve as water levels and operating pressures fluctuate. Other converters may be well balanced at varying loads, but their output may vary widely with fluctuations in the input voltage. The following guidelines have been established for submersible installations to be warrantable when used with a phase converter. 1. Limit pump loading to rated horsepower. Do not load into motor service factor. 2. Maintain at least 3 ft/s flow past the motor. Use a flow sleeve when necessary. 3. Use time delay fuses or circuit breakers in pump panel. Standard fuses or circuit breakers do not provide secondary motor protection. 4. SubMonitor will not work with electronic solid state or electro mechanical phase converters. 5. Current unbalance must not exceed 10%.

Motor leads are not connected red to red, yellow to yellow, etc. Line Connections — Six-Lead Motors 90° Lead Spacing Phase Converters 35 ---PAGE BREAK--- Three-Phase Motors APPLICATION All Franklin three-phase submersible motors are suitable for full-voltage starting. Under this condition the motor speed goes from zero to full speed within a half second or less. The motor current goes from zero to locked rotor amps, then drops to running amps at full speed. This may dim lights, cause momentary voltage dips to other electrical equipment, and shock power distribution transformers. In some cases the power companies may require reduced-voltage starters to limit this voltage dip. There are also times when reduced-voltage starters may be desirable to reduce motor starting torque thus reducing the stress on shafts, couplings, and discharge piping. Reduced-voltage starters also slow the rapid acceleration of the water on start-up to help control upthrust and water hammer. Reduced-voltage starters may not be required if the maximum recommended cable length is used. With maximum recommended cable length there is a 5% voltage drop in the cable at running amps, resulting in about 20% reduction in starting current and about 36% reduction in starting torque compared to having rated voltage at the motor. This may be enough reduction in starting current so that reduced-voltage starters are not required. Three-Lead Motors: Autotransformer or solid-state reduced-voltage starters may be used for soft-starting standard three-phase motors. When autotransformer starters are used, the motor should be supplied with at least 55% of rated voltage to ensure adequate starting torque. Most autotransformer starters have 65% and 80% taps. Setting the taps on these starters depends on the percentage of the maximum allowable cable length used in the system. If the cable length is less than 50% of the maximum allowable, either the 65% or the 80% taps may be used. When the cable length is more than 50% of allowable, the 80% tap should be used. Six-Lead Motors: Wye-Delta starters are used with six-lead Wye-Delta motors. All Franklin 6" and 8" three-phase motors are available in six-lead Wye-Delta construction. Consult the factory for details and availability. Part winding starters are not compatible with Franklin Electric submersible motors and should not be used. Wye-Delta starters of the open-transition type, which momentarily interrupt power during the starting cycle, are not recommended. Closed-transition starters have no interruption of power during the start cycle and can be used with satisfactory results. Reduced-voltage starters have adjustable settings for acceleration ramp time, typically preset at 30 seconds. They must be adjusted so the motor is at full voltage within THREE SECONDS MAXIMUM to prevent excessive radial and thrust bearing wear. If Subtrol-Plus or SubMonitor is used the acceleration time must be set to TWO SECONDS MAXIMUM due to the 3 second reaction time of the Subtrol-Plus or SubMonitor. Solid-state starters AKA soft starts may not be compatible with Subtrol-Plus/ SubMonitor. However, in some cases a bypass contactor has been used. Consult the factory for details. During shutdown, Franklin Electric’s recommendation is for the power to be removed, allowing the pump/motor to coast down. Stopping the motor by ramping down the voltage is possible, but should be limited to three seconds maximum. Franklin Electric offers three different types of motors for non-vertical applications. 1. The Booster motors are specifically designed for booster applications. They are the “Best Choice” for sealed Reverse Osmosis applications. These motors are the result of two years of focused development and bring additional value and durability to booster module systems. These motors are only available to OEMs or Distributors who have demonstrated capability in Booster Module systems design and operation and adhere to Franklin’s Application Manual requirements. 2. The Hi-Temp motors have many of the internal design features of the Booster motor. It’s additional length allows for higher temperature handling and the Sand Fighter sealing system provides greater abrasion resistance. One or both of these conditions are often experienced in open atmosphere applications such as lakes, ponds, etc. 3. The Standard Vertical Water Well (40-125 hp) motors can be adapted to non- vertical applications when applied per the below guidelines. However, they will be more sensitive to application variances than the other two designs. All of the above motors must be applied per the guidelines listed below. In addition, for all applications where the motor is applied in a sealed system, a Submersible Motor Booster Installation Record (Form 3655) or its equivalent must be completed at start-up and received by Franklin Electric within 60 days. A sealed system is one where the motor and pump intake are mounted in a sleeve and the water feeding the pump intake is not open to the atmosphere. Reduced Voltage Starters Inline Booster Pump Systems 36 Continued on next page ---PAGE BREAK--- Three-Phase Motors APPLICATION Design And Operational Requirements 1. Non-Vertical Operation: Vertical Shaft-up to Horizontal (90°) operation is acceptable as long as the pump transmits “down-thrust” to the motor within 3 seconds after start-up and continuously during operation. However, it is best practice to provide a positive slope whenever it is possible, even if it is only a few degrees. 2. Motor, Sleeve, and Pump Support System: The booster sleeve ID must be sized according to the motor cooling and pump requirements. The support system must support the motor’s weight, prevent motor rotation, and keep the motor and pump aligned. The support system must also allow for thermal axial expansion of the motor without creating binding forces. 3. Motor Support Points: A minimum of two support points are required on the motor. One in the motor/pump flange connection area and one in the bottom end of the motor area. The motor castings, not the shell area, are recommended as support points. If the support is a full length support and/or has bands in the shell area, they must not restrict heat transfer or deform the shell. 4. Motor Support Material and Design: The support system shall not create any areas of cavitation or other areas of reduced flow less than the minimum rate required by this manual. They should also be designed to minimize turbulence and vibration and provide stable alignment. The support materials and locations must not inhibit the heat transfer away from the motor. 5. Motor and Pump Alignment: The maximum allowable misalignment between the motor, pump, and pump discharge is 0.025 inch per 12 inches of length (2 mm per 1000 mm of length). This must be measured in both directions along the assembly using the motor/pump flange connection as the starting point. The booster sleeve and support system must be rigid enough to maintain this alignment during assembly, shipping, operation, and maintenance. 6. Lubrication and Heat Resistance: The best motor lubrication and heat resistance is obtained with the factory based propylene glycol fill solution. Only when an application MUST HAVE deionized (DI) water should the factory fill solution be replaced. When a deionized water fill is required, the motor must be derated as indicated on the below chart. The exchange of the motor fill solution to DI water must be done by an approved Franklin service shop or representative using a vacuum fill system per Franklin’s Motor Service Manual instruction. The motor shell then must be permanently stamped with a D closely behind the Serial Number. The maximum pressure that can be applied to the motor internal components during the removal of the factory fill solution is 7 psi (0.5 bar.) Inline Booster Pump Systems (Continued) First: Determine maximum Feed Water Temperature that will be experienced in this application. If the feed water exceeds the maximum ambient of the motor, both the DI water derating and a hot water application derating must be applied. Second: Determine the Pump Load Multiplier from the appropriate Service Factor curve. (Typical 1.15 Service Factor is for 60 Hz ratings & 1.00 Service Factor for 50 Hz ratings). Third: Multiply the Pump Load Requirement times the pump load multiplier number indicated on the vertical axis to determine the Minimum Motor Nameplate Rating. Fourth: Select a motor with a nameplate equal or higher than the above calculated value. 7. Motor Alterations - Sand Slinger & Check Valve Plug: On 6" and 8" motors, the rubber sand slinger located on the shaft must be removed. If a pipe plug is covering the check valve, it must be removed. The special Booster motor already has these modifications. 8. Frequency of Starts: Fewer than 10 starts per 24-hour period are recommended. Allow at least 20 minutes between shutdown and start-up of the motor. 9. Controls-Soft Starters and VFDs: Reduced voltage starters and variable speed drives (inverter drives) may be used with Franklin three-phase submersible motors to reduce starting current, upthrust, and mechanical stress during start-up. The guidelines for their use with submersible motors are different than with normal air cooled motor applications. Refer to the Franklin Electric Application, Installation, and Maintenance (AIM) manual Reduced Voltage Starters section or Variable Speed Submersible Pump Operation, Inverter Drives sections for specific details including required filtering.

Motor Overload Protection: Submersible motors require properly sized ambient compensated Class 10 quick-trip overloads per Franklin’s AIM manual guidelines to protect the motor. Class 20 or higher overloads are NOT acceptable. Franklin’s SubMonitor is strongly recommended for all large submersibles since it is capable of sensing motor heat without any additional wiring to the motor. Applications using Soft Starters with a SubMonitor require a start-up bypass - consult the factory for details. SubMonitor can not be used in applications using a VFD control. 11. Motor Surge Protection: Properly sized, grounded and dedicated motor surge arrestors must be installed in the supply line of the booster module as close to the motor as possible. This is required on all systems including those using soft-starters and variable speed drives (inverter drives). 12. Wiring: Franklin’s lead assemblies are only sized for submerged operation in water to the motor nameplate maximum ambient temperature and may overheat and cause failure or serious injury if operated in air. Any wiring not submerged must meet applicable national and local wiring codes and Franklin Cable Chart Tables 16-21. (Notice: wire size, wire rating, and insulation temperature rating must be known when determining its suitability to operate in air or conduit. Typically, for a given size and rating, as the insulation temperature rating increases its ability to operate in air or conduit also increases.) 13. Check Valves: Spring-loaded check valves must be used on start-up to minimize motor upthrusting, water hammer, or in multiple booster (parallel) applications to prevent reverse flow. Inline Booster Pump Systems (Continued) 14. Pressure Relief Valves: A pressure relief valve is required and must be selected to ensure that, as the pump approaches shut-off, it never reaches the point that the motor will not have adequate cooling flow past it. 15. System Purge (Can Flooding): An air bleeder valve must be installed on the booster sleeve so that flooding may be accomplished prior to booster start-up. Once flooding is complete, the booster should be started and brought up to operating pressure as quickly as possible to minimize the duration of an upthrust condition. At no time should air be allowed to gather in the booster sleeve because this will prevent proper cooling of the motor and permanently damage it. 16. System Flush – Must Not Spin Pump: Applications may utilize a low flow flushing operation. Flow through the booster sleeve must not spin the pump impellers and the motor shaft. If spinning takes place, the bearing system will be permanently damaged and the motor life shortened. Consult the booster pump manufacturer for maximum flow rate through the pump when the motor is not energized. 17. Open Atmosphere Booster Pump Systems: When an open booster is placed in a lake, tank, etc. that is open to atmospheric pressure, the water level must provide sufficient head pressure to allow the pump to operate above its requirement at all times and all seasons. Adequate inlet pressure must be provided prior to booster start-up. Based on 30 °C maximum ambient with cable length of 100 feet or less.

Water Temperature: Feed water on each booster must be continuously monitored and not allowed to exceed the motor nameplate maximum ambient temperature at any time. IF THE INLET TEMPERATURE EXCEEDS THE MOTOR NAMEPLATE MAXIMUM AMBIENT TEMPERATURE, THE SYSTEM MUST SHUTDOWN IMMEDIATELY TO PREVENT PERMANENT MOTOR DAMAGE. If feed water temperatures are expected to be above the allowable temperature, the motor must be derated. See Franklin’s AIM manual Hot Water Applications section for derating guidelines. (The high temperature feed water derating is in addition to the exchange to DI water derating if the motor factory fill solution was exchanged to DI water.) 2. Inlet Pressure: The inlet pressure on each booster module must be continuously monitored. It must always be positive and higher than the (Net Positive Suction Head Requirement) of the pump. A minimum of 20 PSIG (1.38 Bar) is required at all times, except for 10 seconds or less when the motor is starting and the system is coming up to pressure. Even during these 10 seconds the pressure must remain positive and be higher than the (Net Positive Suction Head Requirement) of the pump. Inline Booster Pump Systems (Continued) PSIG is the actual value displayed on a pressure gauge in the system piping. PSIG is the pressure above the atmospheric conditions. If at any time these pressure requirements are not being met, the motor must be de-energized immediately to prevent permanent damage to the motor. Once the motor is damaged, it is usually not immediately noticeable, but progresses and results in a premature motor failure weeks or months after the damage occurred. Motors that will be exposed to pressure in excess of 500 psi (34.47 Bar) must undergo special high pressure testing. Consult factory for details and availability. 3. Discharge Flow: The flow rate for each pump must not be allowed to drop below the motor minimum cooling flow requirement. IF THE MOTOR MINIMUM COOLING FLOW REQUIREMENT IS NOT BEING MET FOR MORE THAN 10 SECONDS, THE SYSTEM MUST BE SHUT DOWN IMMEDIATELY TO PREVENT PERMANENT MOTOR DAMAGE. 4. Discharge Pressure: The discharge pressure must be monitored to ensure that a load toward the motor is present within 3 seconds after start-up and continuously during operation. IF THE MOTOR DISCHARGE PRESSURE IS NOT ADEQUATE TO MEET THIS REQUIREMENT, THE SYSTEM MUST BE SHUT DOWN IMMEDIATELY TO PREVENT PERMANENT MOTOR DAMAGE. 39 ---PAGE BREAK--- Three-Phase Motors APPLICATION 40 Variable Frequency Drive Submersible Motor Requirements Franklin Electric’s three-phase, encapsulated submersible motors can be used with variable frequency drives (VFD) when applied within the guidelines below. All three-phase, encapsulated submersible motors must have the VFD sized based on the motor’s nameplate maximum amps, not horsepower. The continuous rated amps of the VFD must be equal to or greater than the motor’s nameplate maximum amps or warranty will be void. Franklin Electric’s single-phase, 2- and 3-wire, encapsulated submersible motors can only be used with the appropriate Franklin constant pressure controller. Franklin Electric’s submersible motor Application, Installation, Maintenance (AIM) manual should be checked for the latest guidelines and can be found online at www. franklin-electric.com. WARNING: There is a potential shock hazard from contact with and/or touching the insulated cables connected to the variable frequency drive output anytime the motor has energy applied. Output Filter Requirement Test: NOTICE: An incoming power supply or line-side filter for the drive does not replace the need for additional output filters. An output filter is required if the answer is yes to one or both of the items below: #1 - Does the peak voltage at the motor terminals exceed 1000-volts or is the rise time of the VFD's voltage less than 2 micro-seconds? Per NEMA MG 1-2011, the rise time is defined as the time between 10% and 90% of the steady-state voltage DC bus voltage). #2 - Is the motor nameplate voltage more than 379 Volts and is the cable from drive-to-motor more than 50 ft (15.2 NOTICE: More than 99% of the drives applied on water well submersible motors will require the purchase of additional output filtering based on question Output filters can be expensive. However, when needed, it is required for the motor to be considered for warranty. Make sure this item is not overlooked when quoting a job. PWM dV/dt value can be defined as: the rate at which voltage is changing with time or how fast the voltage is accelerating. This information can be supplied by the drive manufacturer or the manufacturer’s drive specification sheet. The dV/dt value cannot be measured with typical field equipment, even when using a true-RMS voltage/amperage multi-meter. Franklin Electric has a line of VFDs that are specifically designed for Franklin application systems. These VFDs are used in the MonoDrive and SubDrive constant pressure systems. Franklin drive systems have the required additional output filtering installed; however, the SubDrive HPX does not. Types of Output Filters: A resistor-inductor-capacitor (RLC) filter has both a high pass filter & a low pass filter section and are considered the best practice, but a high pass reactor filter is also acceptable. Filters should be recommended by the drive manufacturer; for the correct recommendations provide them with answers to all five of the items below. REQUIRED ITEMS FOR PROPER VFD FILTER SIZING: VFD model Carrier frequency setting Motor nameplate voltage Motor nameplate max amps Cable length from the drive output terminals to the motor Input Current & Motor Overload Protection: • Motor input current should be set at the system’s typical operating current when running at nameplate rated voltage and frequency (Hz). • Motor overload protection should be set to trip at 115% of the system’s typical operating current. • Motor overload protection must trip equal to or faster than NEMA Class 10 motor overload curve requirements. Motor Maximum Load Limits: • The system must never operate in excess of the motor nameplate maximum amps. • On 50 Hz motors, nameplate amps are maximum amps as these motors have a 1.0 service factor. ---PAGE BREAK--- Three-Phase Motors APPLICATION Motor Operating Hertz, Cooling Requirements, and Underload Settings: • Standard practice for large VFD installations is to limit the operation to 60 Hz max. Operating at greater than 60 Hz requires special system design considerations. • The motor must never operate below 30 Hz. This is the minimum speed required to provide correct bearing lubrication. • The motor’s operating speed must always operate so the minimum water flow requirements of 0.5 ft/sec for 6-inch & 8-inch motors and 0.25 ft/sec for 4-inch motors is supplied. • The motor underload protection is normally set to trip at 80% of the system’s typical operating current. However, the underload trip point must be selected so that minimum flow requirements are always met. Starting and Stopping Ramp Settings: • The motor must reach or pass the 30 Hz operating speed within 1 second of the motor being energized. If this does not occur, the motor bearings will be damaged and the motor life reduced. • The best stopping method is to turn power off followed by a natural coast to stop. • A controlled stop from 30 Hz to 0 Hz is allowed if the time does not exceed 1 second. Drive Carrier Frequency: • The carrier frequency is set in the field. The drive typically has a selectable range between 2k and 12k Hz. The higher the carrier wave frequency setting, the greater the voltage spikes; the lower the carrier wave frequency setting, the rougher/poorer the shape of the power curve. • The carrier frequency should be set within the range of 4k to 5k Hz for encapsulated submersible motors. Application Function Setting: • If the VFD has a setting of centrifugal pump or propeller fan it should be used. • Centrifugal pumps and fans have similar load characteristics. Variable Frequency Drive Submersible Motor Requirements (Continued) VFD Frequency of Starts: • Keeping the starts per day within the recommended numbers shown in the frequency of starts section of the AIM manual provides the best system life. However, since in-rush current is typically reduced when used with a properly configured VFD, large 3-phase submersible motors can be started more frequently. In all cases a minimum of 7 minutes must be allowed between a power off and the next restart attempt or consecutive restart attempts. NEMA MG1 Above Ground Motor Standard Comments: • Franklin Electric encapsulated submersible motors are not declared inverter duty motors by NEMA MG1 standards. The reason is NEMA MG1 standard part 31 does not include a section covering encapsulated winding designs. • Franklin submersible motors can be used with VFDs without problems or warranty concerns providing Franklin's Application, Installation, Maintenance (AIM) manual guidelines are followed. See Franklin's on-line AIM manual for the latest guidelines. 41 ---PAGE BREAK--- All Motors INSTALLATION 4" Super Stainless — Dimensions (Standard Water Well) 1.508" 1.498" 1.48" MAX 0.030" R MAX 0.97" 0.79" L* 0.161" MAX LEAD BOSS HEIGHT 3.75" DIA. 0.50" MIN.

Jam nut tightening torques recommended for field assembly are shown. Rubber compression set within the first few hours after assembly may reduce the jam nut torque. This is a normal condition which does not indicate reduced seal effectiveness. Retightening is not required, but is permissible and recommended if original torque was questionable. A motor lead assembly should not be reused. A new lead assembly should be used whenever one is removed from the motor, because rubber set and possible damage from removal may prevent proper resealing of the old lead. All motors returned for warranty consideration must have the lead returned with the motor. Assemble coupling with non-toxic FDA approved waterproof grease such as Mobile FM222, Texaco CYGNUS2661, or approved equivalent. This prevents abrasives from entering the spline area and prolongs spline life. A common question is why motor leads are smaller than specified in Franklin’s cable charts. The leads are considered a part of the motor and actually are a connection between the large supply wire and the motor winding. The motor leads are short and there is virtually no voltage drop across the lead. In addition, the lead assemblies operate under water, while at least part of the supply cable must operate in air. Lead assemblies running under water operate cooler. CAUTION: Lead assemblies on submersible motors are suitable only for use in water and may overheat and cause failure if operated in air.

Open master breaker and disconnect all leads from control box or pressure switch (QD type control, remove lid) to avoid electric shock hazard and damage to the meter. 2. Use a megohmmeter set to 1000-volt (500-volt minimum). If using an ohmmeter, set to R X 100k. Zero the meter. 3. Connect one meter lead to any one of the motor leads and the other lead to the metal drop pipe. If the drop pipe is plastic, connect the meter lead to ground. 1. If the ohms value is normal (Table 47), the motor is not grounded and the cable insulation is not damaged. 2. If the ohms value is below normal, either the windings are grounded or the cable insulation is damaged. Check the cable at the well seal as the insulation is sometimes damaged by being pinched. Winding Resistance (Fig 11.) 1. Open master breaker and disconnect all leads from control box or pressure switch (QD type control, remove lid) to avoid electric shock hazard and damage to the meter. 2. Use a multi-meter set to 20 ohms or an ohmmeter set to R X 1 for values under 10 ohms. Use next scale up for values over 10 ohms. Zero the meter. 3. On 3-wire motors measure the resistance of yellow to black (main winding) and yellow to red (start winding). On 2-wire motors: measure the resistance from line-to-line. Three-phase motors: measure the resistance line-to-line for all three combinations. 1. If all ohms values are normal (Tables 13, 22, 24, 25, & 27), the motor windings are neither shorted nor open, and the cable colors are correct 2. If any one value is less than normal, the motor is shorted. 3. If any one ohm value is greater than normal, the winding or the cable is open, or there is a poor cable joint or connection. 4. If some ohms values are greater than normal and some less on single-phase motors, the leads are mixed. See page 48 to verify cable colors. 46 GROUND L2 { TO POWER SUPPLY BLACK { YELLOW RED GROUND POWER MUST BE SHUT OFF BLACK YELLOW RED L1 L2 R Y B L1 TO PUMP MEGGER OR OHMMETER SET AT R X 100K CONNECT THIS LEAD TO GROUND ATTACH THIS LEAD TO WELL CASING OR DISCHARGE PIPE ---PAGE BREAK--- All Motors MAINTENANCE Insulation Resistance Readings The values below are for copper conductors. If aluminum conductor drop cable is used, the resistance will be higher. To determine the actual resistance of the aluminum drop cable, divide the ohm readings from this chart by 0.61. This chart shows total resistance of cable from control to motor and back. Winding Resistance Measuring The winding resistance measured at the motor should fall within the values in Tables 13, 22, 24, 25, & 27. When measured through the drop cable, the resistance of the drop cable must be subtracted from the ohmmeter readings to get the winding resistance of the motor. See table below. Insulation resistance varies very little with rating. Motors of all hp, voltage, and phase rating have similar values of insulation resistance. The table above is based on readings taken with a megohm meter with a 500 VDC output. Readings may vary using a lower voltage ohmmeter; consult Franklin Electric if readings are in question.

Do not touch any live parts. A. VOLTAGE MEASUREMENTS Step 1. Motor Off 1. Measure voltage at L1 and L2 of pressure switch or line contactor. 2. Voltage Reading: Should be ± 10% of motor rating. Step 2. Motor Running 1. Measure voltage at load side of pressure switch or line contactor with pump running. 2. Voltage Reading: Should remain the same except for slight dip on starting. Excessive voltage drop can be caused by loose connections, bad contacts, ground faults, or inadequate power supply. 3. Relay chatter is caused by low voltage or ground faults. If the colors on the individual drop cables cannot be found with an ohmmeter, measure: Cable 1 to Cable 2 Cable 2 to Cable 3 Cable 3 to Cable 1 Find the highest resistance reading. The lead not used in the highest reading is the yellow lead. Use the yellow lead and each of the other two leads to get two readings: Highest is the red lead. Lowest is the black lead. Identification Of Cables When Color Code Is Unknown (Single-Phase 3-Wire Units) EXAMPLE: The ohmmeter readings were: Cable 1 to Cable 2 - 6 ohms Cable 2 to Cable 3 - 2 ohms Cable 3 to Cable 1 - 4 ohms The lead not used in the highest reading (6 ohms) was Cable 3—Yellow From the yellow lead, the highest reading (4 ohms) was To Cable 1—Red From the yellow lead, the lowest reading (2 ohms) was To Cable 2—Black Single-Phase Control Boxes B. CURRENT (AMP) MEASUREMENTS 1. Measure current on all motor leads. 2. Amp Reading: Current in red lead should momentarily be high, then drop within one second to values in Table 13. This verifies relay or solid state relay operation. Current in black and yellow leads should not exceed values in Table 13. 3. Relay or switch failures will cause red lead current to remain high and overload tripping. 4. Open run capacitor(s) will cause amps to be higher than normal in the black and yellow motor leads and lower than normal in the red motor lead. 5. A bound pump will cause locked rotor amps and overloading tripping. 6. Low amps may be caused by pump running at shut-off, worn pump, or stripped splines. 7. Failed start capacitor or open switch/relay are indicated if the red lead current is not momentarily high at starting. CAUTION: The tests in this manual for components such as capacitors, relays, and QD switches should be regarded as indicative and not as conclusive. For example, a capacitor may test good (not open, not shorted) but may have lost some of its capacitance and may no longer be able to perform its function.

To reduce the risk of electrical shock, disconnect power before working on or around the water system. Capacitors inside the SubDrive/MonoDrive Controller can still hold a lethal voltage even after power has been removed. Allow 10 minutes for dangerous internal voltage to discharge. Do not use motor in swimming areas. SubDrives & MonoDrives The Franklin Electric SubDrive/MonoDrive controller is a variable-speed drive that delivers water at a constant pressure. MonoDrive and MonoDriveXT are designed to convert a conventional 3-wire 1/2 hp to 2 hp pump system to a variable speed constant pressure system by simply replaceing the 3-wire control box and pressure switch. The SubDrive 3-Phase models are designed for three-phase motors to provide constant pressure with three-phase performance using single-phase input power. The SubDrive2W is designed to convert a conventional 2-wire 1/2 hp, 3/4 hp and 1 hp pump system to a variable speed constant pressure system by simply replacing the pressure switch.

Pumptec-Plus – Troubleshooting During Installation POSSIBLE CAUSE SOLUTION Unit Appears Dead (No Lights) No Power to Unit Check wiring. Power supply voltage should be applied to L1 and L2 terminals of the Pumptec-Plus. In some installations the pressure switch or other control devices is wired to the input of the Pumptec-Plus. Make sure this switch is closed. Flashing Yellow Light Unit Needs to Be Calibrated Pumptec-Plus is calibrated at the factory so that it will overload on most pump systems when the unit is first installed. This overload condition is a reminder that the Pumptec-Plus unit requires calibration before use. See step 7 of the installation instructions. Miscalibrated Pumptec-Plus should be calibrated on a full recovery well with the maximum water flow. Flow restrictors are not recommended. Flashing Yellow Light During Calibration 2-Wire Motor Step C of the calibration instructions indicate that a flashing green light condition will occur 2 to 3 seconds after taking the SNAPSHOT of the motor load. On some two-wire motors the yellow light will flash instead of the green light. Press and release the reset button. The green should start flashing. Flashing Red and Yellow Lights Power Interruption During the installation of Pumptec-Plus power may be switched on and off several times. If power is cycled more than four times within a minute Pumptec-Plus will trip on rapid cycle. Press and release the reset button to restart the unit. Float Switch A bobbing float switch may cause the unit to detect a rapid cycle condition on any motor or an overload condition on two-wire motors. Try to reduce water splashing or use a different switch. Flashing Red Light High Line Voltage The line voltage is over 253 volts. Check line voltage. Report high line voltage to the power company. Unloaded Generator If you are using a generator the line voltage may become too high when the generator unloads. Pumptec-Plus will not allow the motor to turn on again until the line voltage returns to normal. Overvoltage trips will also occur if line frequency drops too far below 60 Hz. Solid Red Light Low Line Voltage The line voltage is below 207 volts. Check line voltage. Loose Connections Check for loose connections which may cause voltage drops. Loaded Generator If you are using a generator the line voltage may become too low when the generator loads. Pumptec-Plus will trip on undervoltage if the generator voltage drops below 207 volts for more than 2.5 seconds. Undervoltage trips will also occur if the line frequency rises too far above 60 Hz. 61 ---PAGE BREAK--- Electronic Products MAINTENANCE Pumptec-Plus and Pumptec with 3-lights Pumptec-Plus and Pumptec with 3 lights - Troubleshooting After Installation POSSIBLE CAUSE SOLUTION Solid Yellow Light Dry Well Wait for the automatic restart timer to time out. During the time out period, the well should recover and fill with water. If the automatic reset timer of the Pumptec-Plus is set to the manual position, push the reset button to reactivate the unit. If the reset timer is set to manual in the Pumptec, turn off power for 5 seconds to reset the unit. Blocked Intake Clear or replace pump intake screen. Blocked Discharge Remove blockage in plumbing. Check Valve Stuck Replace check valve. Broken Shaft Replace broken parts. Severe Rapid Cycling Machine gun rapid cycling can cause an underload condition. See flashing red and yellow lights section below. Worn Pump Replace worn pump parts and recalibrate. Flashing Yellow Light Stalled Motor Repair or replace motor. Pump may be sand or mud locked. Float Switch A bobbing float switch can cause two-wire motors to stall. Arrange plumbing to avoid splashing water. Replace float switch. Ground Fault Check insulation resistance on motor and control box cable. Solid Red Light Low Line Voltage The line voltage is below 207 volts. Pumptec and Pumptec-Plus will try to restart the motor approximately every two minutes until the line voltage is normal. Loose Connections Check for excessive voltage drops in the system electrical connections (i.e. circuit breakers, fuse clips, pressure switch, and Pumptec-Plus L1 and L2 terminals). Repair connections. Flashing Red Light High Line Voltage The line voltage is over 253 volts. Check line voltage. Report high line voltage to the power company. Flashing Red and Yellow Lights Rapid Cycle The most common cause for the rapid cycle condition is a waterlogged tank. Check for a ruptured bladder in the water tank. Check the air volume control or snifter valve for proper operation. Check setting on the pressure switch and examine for defects. Leaky Well System Replace damaged pipes or repair leaks. Stuck Check Valve Failed valve will not hold pressure. Replace valve. Float Switch A bobbing float switch may cause the unit to detect a rapid cycle condition on any motor or an overload condition on 2-wire motors. To reset a Pumptec, remove power for 5 seconds. To reset a Pumptec-Plus, press and release the reset button. To eliminate float switch bounce, try to reduce water splash or use a different switch. 62 ---PAGE BREAK--- Electronic Products MAINTENANCE QD Pumptec and Pumptec with 2-lights or no lights QD Pumptec & Pumptec – Troubleshooting CHECKS OR SOLUTION If the QD Pumptec or Pumptec trips in about 4 seconds with some water delivery. A. Is the voltage less than 90% of nameplate rating? B. Are the pump and motor correctly matched? C. Is the QD Pumptec or Pumptec wired correctly? For the Pumptec check the wiring diagram and pay special attention to the positioning of the power lead (230 V or 115 Pre-2006 Pumptec used different wiring guidelines. D. For QD Pumptec is your system 230 V 60 Hz or 220 V 50 Hz? If the QD Pumptec or Pumptec trips in about 4 seconds with no water delivery. A. The pump may be airlocked. If there ia a check valve on top of the pump, put another section of pipe between the pump and the check valve. B. The pump may be out of water. C. Check the valve settings. The pump may be dead-heading. D. Pump or motor shaft may be broken. E. Motor overload may be tripped. Check the motor current (amperage). If the QD Pumptec or Pumptec will not timeout and reset. A. Check switch position on side of circuit board on Pumptec. QD Pumptec check timer position on top/front of unit. Make sure the switch is not between settings. B. If the reset time switch is set to manual reset (position QD Pumptec and Pumptec will not reset (turn power off for 5 sec. then back on to reset). If your pump/motor will not run at all. A. Check voltage. B. Check wiring. C. Remove the QD Pumptec from the control box. Reconnect wires in box to original state. If motor does not run the problem is not QD Pumptec. Bypass Pumptec by connecting L2 and motor lead with jumper. Motor should run. If not, the problem is not Pumptec. D. On Pumptec only check that Pumptec is installed between the control switch and the motor. If your QD Pumptec or Pumptec will not trip when the pump breaks suction. A. Be sure you have a Franklin motor. B. Check wiring connections. On Pumptec is lead power (230 V or 115 V) connected to correct terminal? Is motor lead connected to correct terminal? C. Check for ground fault in the motor and excessive friction in the pump. D. The well may be “gulping” enough water to keep QD Pumptec or Pumptec from tripping. It may be necessary to adjust the QD Pumptec or the Pumptec for these extreme applications. Call the Franklin Electric Service Hotline at [PHONE REDACTED] for information. E. On Pumptec applications does the control box have a run capacitor? If so, Pumptec will not trip. (Except for Franklin 1.5 hp motors). If your QD Pumptec or Pumptec chatters when running. A. Check for low voltage. B. Check for waterlogged tank. Rapid cycling for any reason can cause the QD Pumptec or the Pumptec relay to chatter. C. On Pumptec make sure the L2 and motor wires are installed correctly. If they are reversed, the unit can chatter. QD Pumptec and the old 2-light version of Pumptec are load sensing devices that monitor the load on submersible pumps/motors. If the load drops below a preset level for a minimum of 4 seconds the QD Pumptec or the Pumptec will shut off the motor. The QD Pumptec is designed and calibrated expressly for use on Franklin Electric 230 V 3-wire motors (1/3 to 1 hp.) The QD Pumptec must be installed in QD relay boxes. The Pumptec is designed for use on Franklin Electric 2- and 3-wire motors (1/3 to 1.5 hp) 115 and 230 V. The Pumptec is not designed for jet pumps. 63 ---PAGE BREAK--- Electronic Products MAINTENANCE NUMBER OF FLASHES OR DIGITAL DISPLAY FAULT POSSIBLE CAUSE CORRECTIVE ACTION 1 MOTOR UNDERLOAD - Overpumped well - Broken shaft or coupling - Blocked screen, worn pump - Air/gas locked pump - SubDrive not set properly for pump end - Frequency near maximum with less than 65% of expected load, 42% if DIP #3 is “on” - System is drawing down to pump inlet (out of water) - High static, light loading pump - reset DIP switch #3 to “on” for less sensitivity if not out of water - Check pump rotation (SubDrive only) reconnect if necessary for proper rotation - Air/gas locked pump - if possible, set deeper in well to reduce - Verify DIP switches are set properly 2 UNDERVOLTAGE - Low line voltage - Misconnected input leads - Dragging or failed cooling fan - Line voltage low, less than approximately 150 VAC (normal operating range = 190 to 260 VAC) - Check incoming power connection and correct or tighten if necessary correct incoming voltage - check circuit breaker of fuses, contact power company - Disconnect fan.
