Disconnect power before working on pump, motor, pressure switch, or wiring.
MOTOR SWITCH SETTINGS
Dual-voltage motors (motors that can operate at either 115 or
230 volts), are set at the factory to 230 volts. Do not change
motor voltage setting if line voltage is 230 volts, or if you
have a single voltage motor.
NOTE: Never wire a 115 volt motor to a 230 volt line.
Remove Motor End Cover
If you have a dual-voltage motor, and will connect it to 115
volts, follow the procedure below.

Figure 6: Removing Motor End Cover
You will need to remove the motor end cover to change the
voltage setting.
Your motor terminal board (located under the motor end
cover) should look like that shown below.

To change to 115 volts:
Step 1. Make sure power is off.
Step 2. Turn the dial counter-clockwise until 115 shows in

Pressure Switch Wiring
Motor wires connect here.
Connect the green (or bare copper) ground wire
to the green ground screw.

Step 5. Go to Wiring Connections below.
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.

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 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 inspec-

Power supply wires connect here.
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.
Clamp the power cable to prevent strain
on the terminal screws.
