Disconnect power before working on pump, motor, pressure switch, or wiring.
Hazardous voltage. Can shock, burn, or kill. Connect ground
wire before connecting power supply wires. Use the wire size (including
the ground wire) specified in the wiring chart. If possible, connect the
pump to a separate branch circuit with no other appliances on it.
Explosion hazard. Do not ground to a gas supply line.
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 sin-
gle 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.
Figure 6: Motor wiring connections through Pressure Switch. Match motor voltage to line voltage.
Your Motor Terminal Board (under the motor end cover)
and Pressure Switch look like one of those shown below.
Convert to 115 Volts as shown. Do not change motor
wiring if line voltage is 230 Volts or if you have a single
voltage motor. Connect power supply as shown for your
type of switch and your supply voltage.

230 Volt: Connect 2 hot wires (black and red)
here and cap the white (neutral) wire. It does
not matter which wire goes to which screw.
115 Volt: Connect one hot wire (black or red)
to one of these screws (it doesn't matter
which one). Connect the white (neutral) wire
to the other screw. Cap any remaining
black or red wires.
