Risk of damage to pump or other equipment.
• The motor on this pump is guaranteed by the manufacturer. In event of failure, it must be returned to an authorized product
reseller for review and disposition. Product warranty is void if product is disassembled or reviewed by any other party.
• Install the pump in a properly developed well. Undeveloped well water often contains abrasives that can damage the pump.
• Check that the well is deep enough to allow the pump to be set at least 5 ft from the bottom.
• Do not set pump below the casing perforations or well screen unless there is an adequate flow of water over the motor for cooling
purposes is ensured.
• Determine the correct pump setting from the driller’s record, taking into account the static water level and the draw-down at the
proposed pumping rate.

Electrical Connections
Employ a licensed electrician or water systems contractor to ensure installation is done properly. All
wiring must be done in accordance with national and local electrical codes. Follow the cable splicing kit
instructions.
1. Make sure the power supply corresponds with the electrical rating of the motor.
• For 3-wire, single phase pumps, check electrical rating of the 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 con-
nections.
5. For three-wire, single-phase pumps,
make wiring connections and install the
control box.
• Mount in an area protected from
rain, snow, high temperatures, and
temperatures below 14 °F (-10 °C).
• Refer to the control box’s wiring dia-
gram.
• Install a magnetic contac-
tor 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. Install a separate lightning
arrestor close to the wellhead.
7. Test the unit. Brace pump shell
and apply power momentarily.
8. Ensure pump rotation is clock-
wise when viewed from pump
discharge.
9. Place the motor and pump
labels in the circuit breaker
box for future reference.
Physical Installation
Refer to “Typical Installation” on page 2.
1. Confirm that 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” diameter to 1/4” 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 for installations up to 600 ft (180m).
• For deeper settings, use schedule 40 pipe for the bottom 600 feet (180m) and schedule 80 for
the remainder.

• If using plastic pipe, refer to manufacturer’s recommendations for depth and pressure.
• Keep pipes clean and free from debris and 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 100 ft (60m), install check valves in the drop pipe at intervals of 100
ft (60m) or as specified by the manufacturer.
• Install an inline check valve in the discharge line within 25 ft 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.
• 4" submersible pumps with a 1-1/4" or 2”discharge contain a spring-loaded removable poppet
style check valve assembly. Refer to “Maintenance” on page 5 to remove valve for drain back.
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 ft (3m).
• Take care not to scrape or pinch the cable against the well casing.
• Keep the cable slack when using plastic drop pipe to allow for stretching.
• Use an ohmmeter or megger to make insulation and continuity checks.
8. Lower pump at least 5 ft (1.5m) from bottom of well and above well screen or casing perforations.
9. Test the well. Refer to “Well Test” on page 4.
10. Place a sanitary well seal or pit-less adapter over top of well per manufacturer’s recommendations.
Well Test
1. Install a partially opened gate valve on the end of the pipe.
2. Start the pump and slowly open valve to full flow.
3. If the discharge water is not clear within 30 minutes, stop pump and take necessary steps to correct.
4. Close valve until maximum required system flow rate is obtained.
5. 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” on page 4 to correct issue.
Low-Yielding Well
1. Install a smaller pump. Consult licensed water systems professional contractor for sizing.
2. Install 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 floatless liquid level control to work with the pressure switch.
5. Install 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.
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.
