ELECTRICAL
Motor Switch Settings
If the motor can operate at either 115 or 230 volts, it is 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.
Remove Motor End Cover
You will need to remove the motor end cover to change the volt-
age setting. The illustration above also shows the pressure
switch. If the power supply connection still needs to be made,
the pressure switch cover will need to be removed.
Your motor terminal board (located under the motor end cover)
should look like the one at right.
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. Reinstall the Motor end cover
4. Go to Wiring Connections, Page 6.
Hazardous voltage. Can shock, burn, or kill.
Connect ground wire before connecting power supply
wires. Use the wire size (including the ground wire) speci-
fied in the wiring chart.
If possible, connect the pump to a sep-
arate branch circuit with no other appliances on it.
Explosion hazard. Do not ground to a gas sup-
ply line.
