Motor Switch Settings (Figure 8)
Motors are designed to run on either 115 volt or 230 volt
current. Be sure switch is set properly for the incoming
voltage. SETTING SWITCH FOR INCORRECT VOLTAGE
WILL DAMAGE MOTOR AND VOID WARRANTY! IF YOU
DO NOT KNOW THE SUPPLY VOLTAGE CONTACT LI-
CENSED ELECTRICIAN.
Wiring Pressure Switch
Attach the wires from the power source to the pressure
switch following the directions provided under the cover
of the pressure switch. Remove the pressure switch cover
and follow wiring directions under the cover lid. Be sure to
ground wire is properly connected (Figure 9).
Disconnect power before working on
pump, motor, pressure switch or wiring
Motor may be hot. Allow to cool 20
minutes.
Water pressure may have built up in
the pump, pipes and/or tank. Drain
water to relieve pressure.

Wiring
Risk of electric shock.
Can shock, burn or kill.
1. To avoid dangerous or fatal electrical shock, turn OFF
power to circuit before working on electrical
connections.
2. Ground motor before connecting to electrical power
supply. Failure to ground motor can cause severe or
fatal electrical shock hazard.
3. Supply voltage must be within +/- 10% of nameplate
voltage. Incorrect voltage can cause re or damage
motor and voids warranty. If in doubt consult a
licensed electrician.
4. Use wire size specied in Wiring Chart (below). If
possible, connect pump to a separate branch circuit
with no other appliances on it.
5. Do not ground to a gas supply line.
6. Wire motor according to diagram on motor nameplate.
If nameplate diagram diers from diagrams above,
follow nameplate diagram.
7. If this procedure or the wiring diagrams are
confusing, consult a licensed electrician.
8. Pump must be on dedicated circuit with no other
equipment on circuit.
