Voltage is factory set to 230 volts. To change to 115 volts:
1. Make sure power is off.
2. Pull the voltage change plug off of the tabs.
3. Move the voltage change plug to the 115 volt position. The
plug will now cover 2 metal tabs and the arrow on the plug
will line up with the 115V arrow on the label (see Figure 5).
4. Attach the incoming power leads to the two outer screws
on the pressure switch as shown in Figure 4.
5. Attach the ground wire to one of the grounding
connections, shown in Figure 4.
6. If there are other wires, they should be capped.
7. Reinstall the Motor end cover.

Your motor terminal board (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.
