Disconnect power before working on pump, motor, pressure switch, or wiring.
MOTOR SWITCH SETTINGS
NOTE: 1/2 HP motors are wired for 115 volts only, and have no motor wiring to change.
3/4 HP or 1 HP motor terminal boards (located under the motor end cover) should look like one of those below.
If the motor can operate at either 115 or 230 volts, it is set at the factory to 230 volts. Do not change motor wiring
if line voltage is 230 volts, or if you have a single voltage motor.
Never wire a 115 volt motor to a 230 volt line.

Voltage is factory set to 230 volts. To change to 115 volts:
1. Make sure power is off.
2. Turn the dial counter-clockwise until 115 shows in
the dial window as shown in Figure 7.

3. Attach the incoming power leads to the two outer
screws on the pressure switch as shown in Figure 6.
4. Attach the ground wire to the grounding connections
as shown in Figure 6.
5. If there are other wires, they should be capped.
6. Reinstall the Motor end cover.
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.

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 inspector for code information.
