ELECTRICAL
These pumps come equipped with TEFC motors, 115/230V
dual voltage, factory pre-wired for 230 volts. Your motor’s
wiring diagram (located in the cover to the motor junction
box) should match the diagram shown below.
Follow the diagram to connect the motor leads correctly and
to connect the motor to the power supply. If the wiring dia-
gram in the motor junction box does not match the diagram
shown below, follow the diagram in the junction box.
Hazardous voltage. Can shock, burn, or
cause death.
Disconnect power to motor before working on
pump or motor. Ground motor before connecting to power
supply.
Wiring
Ground motor before connecting to electrical power
supply. Failure to ground motor can cause severe or fatal
electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn OFF
power to motor before working on electrical connections.
Supply voltage must be within ±10% of nameplate volt-
age. Incorrect voltage can cause fire or damage motor and
voids warranty. If in doubt, consult a licensed electrician.
Use wire size specified in Wiring Chart (below). If pos-
sible, connect pump to a separate branch circuit with no
other appliances on it.
Wire motor according to diagram in motor junction box
cover. If junction box cover diagram differs from diagrams
above, follow junction box cover diagram.
1.
Install, ground, wire, and maintain your pump in compli-
ance with the National Electrical Code (NEC) in the U.S.,
or the Canadian Electrical Code (CEC), as applicable,
and with all local codes and ordinances that apply.
Consult your local building inspector for code informa-
tion.
2.
Provide a correctly fused disconnect switch for protection
while working on motor. For switch requirements, consult
your local building inspector for information about codes.
3.
Disconnect power before servicing motor or pump. If the
disconnect switch is out of sight of pump, lock it open
and tag it to prevent unexpected power application.
4.
Ground the pump permanently using a wire of the same
size as that specified in Wiring Chart (below). Make
ground connection to green grounding terminal in motor
junction box marked GRD. or
.
5.
Connect ground wire to a grounded lead in the service
panel or to a metal underground water pipe or well cas-
ing at least 10 feet long. Do not connect to plastic pipe or
insulated fittings.
6.
Protect current carrying and grounding conductors from
cuts, grease, heat, oil, and chemicals.
7.
Connect current carrying conductors as shown in Figure
5, above. When replacing motor, check wiring diagram in
motor junction box against Figure 5. If the motor wiring
diagram does not match the diagram in Figure 5, follow
the diagram in the motor junction box.
8.
Motor has automatic internal thermal overload protection.
If motor has stopped for unknown reasons, thermal over-
load may restart it unexpectedly, which could cause
injury or property damage. Disconnect power before ser-
vicing motor.
9.
If this procedure or the wiring diagrams are confusing,
consult a licensed electrician.
