CORRECTIVE ACTION
Be sure switch is on.
Replace fuse or reset circuit breaker.
DISCONNECT POWER; Replace starting switch.
Refer to instructions on wiring (Page 6). DISCONNECT POWER; check and
tighten all wiring.
Refer to instructions on wiring.
Check voltage being supplied to motor. Install heavier wiring if wire size is
too small (See Electrical / Wiring Chart).
In new installation:
1. Re prime according to instructions.
2. Check all connections on suction line, with soapy water or
shaving cream.
3. Replace foot valve or check valve.
4. Re pipe using size of suction and discharge ports on pump.
In installation already in use:
1. Check all connections on suction line and shaft seal with soapy water.
2. Lower suction line into water and re prime. If receding water level
in well exceeds 25' (7.6M), a deep well pump is needed.
Clean impeller.
Replace check valve or foot valve.
Thaw pipes. Bury pipes below frost line. Heat pit or pump house.
Raise foot valve and/or strainer above bottom of water source.
Clean foot valve and strainer.
A deep well jet will be needed if your well is more than 25' (7.6M)
depth to water.
Replace with plastic pipe where possible, otherwise with new steel pipe.
Re pipe using size of suction and discharge ports on pump.
Add additional well points.
STOP PUMP, tighten clamp nut 1 2 turns. Alternately tighten and tap on
clamp with mallet to seat O Ring. Do not overtighten.
