ELECTRICAL
Wiring
Risk of dangerous or fatal
electric shock. Connect
ground wire before connecting
power supply wires. Incorrect
voltage can cause a fire or
seriously damage the motor and
voids the warranty. The supply
voltage must be within ±10% of
the motor nameplate voltage.
Do not alter the wiring in the
motor. Verify motor data voltage is correctly matched to pow-
er source voltage. Never connect a 110/127 voltage motor to a
220-240 voltage power source.
Maintain your pump in compliance with all local codes and
ordinances that apply. Consult your local building inspector for
code information.
If in doubt, consult a licensed electrician.
Use wire size specified in wiring chart. If possible, con-
nect the pump to a separate branch circuit with no other
appliances on it.
1. Install, ground, wire and maintain the pump in accor-
dance with your local electrical code and all other
codes/ordinances that apply. Consult your local build-
ing inspector for code information.
2. Connect the ground wire first. The ground wire must
be a solid copper wire at least as large as the power
supply wires and must meet local and national code
requirements.
Explosion hazard. Do not ground to a gas
supply line.
• If you install a pressure switch, there must be a solid
metal connection between pressure switch and motor
to provide motor grounding protection. If the pressure
switch is not connected to the motor, connect the
ground screw in the switch to the motor ground screw.
Use a solid copper wire at least as large as power
supply wires.
WARNING
Lubrication
The motor is lubricated at the factory for the life of
the bearings. The pump seal is water cooled and self
lubricating.
Pump Service
Hazardous voltage. Can shock, burn, or
cause death. Unplug the pump before servicing it. Do not
handle the pump or attempt to work on the pump with
wet hands or while standing on a wet or damp floor.
The motor has an auto-reset thermal overload protector.
If the motor overheats, the overload will cut off the power
to prevent damage and will reset after the motor cools. If
the overload trips repeatedly, check the pump for the cause
(low voltage, a clogged impeller, etc.).

* When using fuses, dual element or Fusetron time delay fuses are recommended for all motor circuits.
• Connect the ground wire to a grounded lead in the
service panel, a metal underground water pipe, a well
casing at least 10’ (3M) long, or to a ground electrode
provided by the power company.
Connect the cable to the pump as shown in Figure 2.
