Risk of electric shock . Can shock, burn or kill. Disconnect power before working on pump, motor,
pressure switch, or wiring.
Risk of fire . Never connect a 115 volt motor to a 230 volt line.
Check Voltage Setting
1. Turn off power to the pump!
2. Determine if the power supplied to the pump is
115 or 230 volts.
3. A qualified person must install electrical wiring.
4. The voltage switch is factory set to 115 volts. If you
have 115 volt service, do not change the selection.
1/2 HP motors are preset at the factory for 115 volts.
5. To change the voltage (if necessary), remove the
motor capacitor cover and slide the switch fully to
the correct voltage.
6. Reinstall the cover.
Do Not Turn on Power Yet!
