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.
NOTICE: Never wire a 115 volt motor to a 230 volt line.
NOTICE: Wire TEFC motors according to wiring diagram
in junction box on motor. Be sure motor is connected for
correct line voltage.
NOTICE: Wire 3-Phase motors according to wiring
diagram on motor. Be sure motor is connected for
correct line voltage.
Remove Motor End Cover
If you have a dual-voltage motor, and will connect it to
115 volts, follow the procedure below.
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 the one below.
Dial Type voltage Selector
To change to 115 volts:
1. Make sure power is off.
2. Turn the dial counter-clockwise until 115 shows in
the dial window.
3. Attach the power lead wires to the power lead
terminals. Make sure the wires are secure.
4. Attach the ground wire to the green ground screw.
5. Reinstall the Motor end cover.
Go to Wiring Connections below.
Hazardous voltage. Can shock, burn, or
kill. 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.
Explosion hazard. Do not ground to a gas
supply line.
