Electrical 7
Disconnect power before working on pump, motor, pressure switch, or wiring.
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.
NOTE: Never wire a 115 volt motor to a 230 volt line.
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 that shown below.
To change to 115 volts:
Step 1. Make sure power is off.
Step 2. Turn the dial counter-clockwise until 115 shows
in the dial window.
Step 3. The wires from the pressure switch should
already be attached to to power lead terminals.
Step 4. Reinstall the Motor end cover.

Step 5. Go to Wiring Connections below.
Hazardous voltage. Can shock, burn, or
kill. Connect ground wire before connecting power sup-
ply 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 appli-
ances on it.
Explosion hazard. Do not ground to a gas
supply line.
