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 the one 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.

Dial Type Voltage Selector

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 15.

3.Attach the incoming power leads to the two outer screws on the pressure switch as shown in Figure 14.

4.Attach the ground wire to the grounding connections as shown in Figure 14.

5.If there are other wires, they should be capped.

6.Reinstall the Motor end cover.
