WARNING

Risk of severe injury or death by electrical shock, or damage to system.

• Always disconnect the electrical power before touching the pump.
• A ground fault circuit interrupter (GFCI) is required.
• If the power cord is damaged, it must only be replaced by qualified personnel.

Employ a licensed electrician or water systems contractor to ensure installation is done properly. Follow cable splicing kit instructions.

1. Make sure the supply voltage and current ratings correspond with the electrical ratings of the motor and control box.
2. Install a fused disconnect switch or circuit breaker.
3. Ground the pump and the distribution panel with the motor’s green conductor.
4. For two-wire pumps, make wiring connections.
5. For three-wire, single-phase pumps, make wiring connections.
   • Install a magnetic contactor if the pressure switch is not sufficient to handle the motor’s electrical rating. The pressure switch is then used as a pilot circuit to control the contactor.
6. For three-wire, single-phase pumps, install control boxes in accordance to the control box’s manual and the electrical code.
   • Mount control boxes in an area protected from rain, snow, high temperatures, and temperatures below 14 °F (-10 °C).
7. For 3-phase pumps, install a magnetic starter equipped with quick-trip, ambient compensated heaters, electronic adjustable overload, soft start, or VFD of correct horsepower size.
8. For 3-phase motors, install a separate lightning arrestor close to the wellhead.
9. Test the unit. Brace pump shell and apply power momentarily.
10. For three phase motors, ensure pump rotation is counterclockwise when viewed from pump discharge.
    • Interchange any two leads at the magnetic starter to change rotation.
11. Place the motor and pump labels in the circuit breaker box for future reference.
    

Physical Installation

Refer to “Typical Installations”

1. Confirm the motor’s lead wires are secure under the pump’s lead guard.

2. Install a pressure tank per manufacturer’s recommendations.

3. Attach a 3 /16-inch to 1 /4-inch diameter steel safety cable to pump.
   IMPORTANT : If using a different type of cable, confirm the system weight does not exceed the limit.

4. Attach schedule 40 galvanized pipes to pump.

   • If using plastic pipe, refer to manufacturer’s recommendations for depth and pressure.
   • Keep pipes clean and free from debris.
   • Use pipe sealant on all fittings.

5. Install system check valves.
   IMPORTANT: Install only positive sealing check valves. Never use swing type check valves.

   • For installations more than 200 feet (61 m), install check valves in the drop pipe at intervals of 200 feet (60 m) or as specified by the check valve manufacturer.
   • Install an in-line check valve in the discharge line within 25 feet (7.6 m) of the pump and below the draw-down level of the water supply.
   • If permitted by local codes, install a relief valve between the wellhead and the pressure tank.

6. Install a torque arrestor just above the pump.

7. Fasten the electrical cable to the drop pipe with clamps or appropriate tape every 10 feet (3 m).

   • Do not scrape or pinch the cable against the well casing.
   • Keep the cable slack when using plastic drop pipe to allow for stretching.
   • Check continuity and insulation resistance with an ohmmeter and megger.

8. Lower pump to a minimum of 5 feet (1.5 m) from bottom of well and above well screen or casing perforations.

9. Test the well. Refer to “Well Test” on page 6.

10. Place a sanitary well seal or pit-less adapter over top of well per manufacturer’s recommendations.

Well Test

NOTICE

Risk of damage to pump or other equipment.

• Never run pump unless it is completely submerged in water to avoid pump and motor damage
• Air drawn into the pump can cause an airlock under certain conditions.

1. Install a partially opened gate valve on the end of the pipe.
2. Start the pump and slowly open valve to full flow.
   • If the discharge water is not clear within 30 minutes, stop pump and take necessary steps to correct.
3. Adjust valve until maximum required system flow rate is obtained.
4. Ensure the pump output is not greater than the yield of the well (low-yielding) by monitoring the well draw-down level at the maximum system flow rate.
   • Refer to “Low-Yielding Well”  to correct issue.

Low-Yielding Well

1. Install a smaller pump.
   • Consult licensed water systems professional contractor for sizing.
2. Add additional length of drop pipe to place pump lower in well.
3. Install a Franklin Pumptec or similar electronic run-dry sensor.
4. Install a float-less liquid level control to work with the pressure switch.
5. Place a flow control valve in the discharge line upstream from the pressure switch to restrict output.
   • A pressure tank with a bonded diaphragm, air cell, or water bag is recommended.
6. Install a low-pressure cut-off switch.

MAINTENANCE

Check Valve Replacement

NOTICE

Risk of damage to pump or other equipment.

• Fluid draining back through the pump can cause the pump to rotate backwards. If pump/motor starts during this time, damage to the pump can occur.

Most 4-inch submersible pumps come standard with an internal check valve to prevent water back flow.

To remove:

1. If the pump discharge has a snap ring blocking the check valve, remove using a standard size snap ring tool.
2. Unscrew the check valve assembly (clockwise) using a T-handle wrench, sold separately.
   

NOTE : Check valves are reverse (left-hand) threaded.
For reassembly, tighten the check valve to 15 inch-pounds.
