SINGLE PhASE WIRING INSTRUCTIONS
FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE HANDLING. Single phase
pumps are supplied with a 3-prong grounded plug to help protect you against the possibility of electrical shock. DO NOT UNDER ANY CIRCUM-
STANCES REMOVE THE GROUND PIN. The 3-prong plug must be inserted into a mating 3-prong grounded receptacle. If the installation does not
have such a receptacle, it must be changed to the proper type, wired and grounded in accordance with the National Electrical Code and all applicable
local codes and ordinances.
“Risk of electrical shock” Do not remove power supply cord and strain relief or connect conduit directly to the pump.
Installation and checking of electrical circuits and hardware should be performed by a qualified licensed electrician.
Units supplied without a plug (single and three phase) and single phase nonautomatic units with a 20 amp plug must have a motor
control and liquid level control provided at time of installation. The control device should have suitable voltage, ampere, frequency, grounding and
horsepower rating for the pump to which it is connected.
ELECTRICAL PRECAUTIONS- Before servicing a pump, always shut off the main power breaker and then unplug the pump - making
sure you are wearing insulated protective sole shoes and not standing in water. Under flooded conditions, contact your local electric company or a
qualified licensed electrician for disconnecting electrical service prior to pump removal.
Submersible pumps contain oils which becomes pressurized and hot under operating conditions - allow 2½ hours after disconnecting
before attempting service.
If the above checklist does not uncover the problem, consult the factory - Do not attempt to service or otherwise disassemble pump. Service must
be performed by an Authorized Service Station.

CONDITION COMMON CAUSES
A. Pump will not start or run. Check fuse, low voltage, overload open, open or incorrect wiring, open switch, impeller or seal bound mechanically,
defective capacitor or relay when used, motor or wiring shorted. Float assembly held down. Switch defective,
damaged, or out of adjustment.
B. Motor overheats and trips overload
or blows fuse.
Incorrect voltage, negative head (discharge open lower than normal) impeller or seal bound mechanically, defective
capacitor or relay, motor shorted.
C. Pump starts and stops too often. Float tight on rod, check valve stuck or none installed in long distance line, overload open, level switch(s) defective,
sump pit too small.
D. Pump will not shut off. Debris under float assembly, float or float rod bound by pit sides or other, switch defective, damaged or out of
adjustment.
E. Pump operates but delivers little or
no water.
Check strainer housing, discharge pipe, or if check valve is used vent hole must be clear. Discharge head
exceeds pump capacity. Low or incorrect voltage. Incorrect motor rotation. Capacitor defective. Incoming water
containing air or causing air to enter pumping chamber.
F. Drop in head and/or capacity after
a period of use.
Increased pipe friction, clogged line or check valve. Abrasive material and adverse chemicals could possibly
deteriorate impeller and pump housing. Check line. Remove base and inspect.
