ELECTRICAL
Hazardous voltage. Can shock, burn, or
cause death. When installing, operating, or servicing this
pump, follow safety instructions listed below.
1. DO NOT splice the electrical power cord.
2. DO NOT allow electrical cord plug to be submerged.
3. DO NOT use extension cords. They are a fire hazard
and can reduce voltage sufficiently to prevent
pumping and/or damage motor.
4. DO NOT handle or service pump while it is connected to
power supply.
5. DO NOT remove grounding prong from plug or modify
plug.To protect against electrical shock, the power
cord is a three-wire conductor and includes a
3-prong grounded plug. Plug pump into a 3-wire,
grounded, grounding-type receptacle. Connect pump
according to electrical codes that apply.
For automatic operation, plug or wire pump into an
automatic float switch or pump controller. Pump will run
continuously when plugged directly into an electrical
outlet. Connect or wire pump to its own individual branch
circuit with no other outlets or equipment in the circuit.
Size fuses or circuit breakers according to chart on Page 2.
Risk of electrical shock and fire. Can burn
or cause death. Be sure that power supply information
(Voltage/Hertz/Phase) on pump motor nameplate matches
incoming power supply exactly. Install pump according to
all electrical codes that apply.

OPERATION

NOTICE: Do not allow pump to run in a dry sump. It will
void the warranty and may damage the pump.
WARNING
Risk of electrical shock.
Can burn or kill.
Do not lift pump by
power cord.
For parts or assistance, call Master Plumber Pump Customer Service at
An automatic overload protector in the motor will protect
motor from burning out due to overheating/overloading.
When motor cools down, overload protector will
automatically reset and start motor.
If overload trips frequently, check for cause. It could be a
stuck impeller, wrong/low voltage, or electrical failure in
motor. If an electrical failure in the motor is suspected,
have it serviced by a competent repairman.
Pump is permanently lubricated. No oiling or greasing is
required.
SERVICE
cause death. Before removing pump from basin for
service, always disconnect electrical power to pump
and control switch.
Do not lift pump by power cord. See "Cord Lift Warning"
below.
Submerge pump in a disinfectant solution (chlorox or
chlorine) for at least one hour before disassembling
pump.
The pump motor contains a special lubricating oil which
should be kept clean and free of water at all times.
Check operation by filling sump with water and observing
pump operation through one complete cycle.
or property damage. Failure to make this operational
check may lead to flooding and premature failure.
NOTICE: This unit is not designed for applications
involving salt water or brine! Use with salt water or brine
will void warranty.
CORD LIFT WARNING
Hazardous voltage. Can shock, burn, or
Risk of electrical shock. Can burn or kill.
Risk of flooding. May cause personal injury
1. Attempting to lift or support pump by
power cord can damage cord and cord
connections.
2. Cord may pull apart, exposing bare
wires with possibility of fire or electri-
cal shock.
3. Lifting or supporting pump by power
cord will void warranty.
4. Use lifting ring or handle on top of
pump for all lifting/lowering of pump.
Disconnect power to pump before
doing any work on pump or attempting
