WIRING CONNECTIONS

Fire hazard. 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.
NOTICE: Dual-voltage motors are factory wired for 230 volts. If
necessary, reconnect the motor for 115 volts, as shown. Do not
alter the wiring in single voltage motors.
Install, ground, wire, and maintain your pump in
compliance with the United States National Electrical
Code (NEC) or the Canadian Electrical Code (CEC), as
applicable, and with all local codes and ordinances that
apply. Consult your local building inspector for code
information.

Connection Procedure:

1. Connect the ground wire first as shown in Figure 9.
The ground wire must be a solid copper wire at least
as large as the power supply wires.

2. There must be a solid metal connection between the
pressure switch and the motor for motor grounding
protection. If the pressure switch is not connected
to the motor, connect the green ground screw in the
switch to the green ground screw under the motor
end cover. Use a solid copper wire at least as large
as the power supply wires.
3. Connect the ground wire to a grounded lead in a
service panel, to a metal underground water pipe, to
a metal well casing at least ten feet (3M) long, or to a
ground electrode provided by the power company or
the hydro authority.
4. Connect the power supply wires to the pressure
switch as shown in Figure 9.
