1. Confirm the motor's lead wires are secure under the pump's lead guard.
2. Install a pressure tank per manufacturer's recommendations.

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
10. Place a sanitary well seal or pit-less adapter over top of well per manufacturer's recommendations.
Well Test
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 cor-
rect.
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.
