NOTICE 1/2 HP motors are dual voltage and are factory set to 115 V. 3/4 and 1 HP motors are also dual voltage, but
are factory set to 230 V. Motor terminal board (located under the motor end cover) should look like that shown below.
Use the instructions to set your motor to match your power source.

3. Attach the incoming power leads to the two outer
screws on the pressure switch as shown in Figure 6.
4. Attach the ground wire to the grounding connections
as shown in Figure 6.
5. If there are other wires, they should be capped.

voltage, as shown. Do not alter the wiring in single
voltage motors.
Install, ground, wire, and maintain your pump in
compliance with the National Electrical Code (NEC) or
the Canadian Electrical Code (CEC), as applicable, and
with all local codes and ordinances that apply. Consult
your local building inspector for code information.
Connection Procedure
1. Connect the ground wire first as shown in Figure 6.
The ground wire must be a solid copper wire at least
as large as the power supply wires.
2. There must be a solid metal connection between the
pressure switch and the motor for motor grounding
protection. If the pressure switch is not connected
to the motor, connect the green ground screw in the
switch to the green ground screw under the motor
end cover. Use a solid copper wire at least as large
as the power supply wires.
3. Connect the ground wire to a grounded lead in a
service panel, to a metal underground water pipe, to
a metal well casing at least ten feet (3 m) long, or to
a ground electrode provided by the power company
or the hydro authority.
4. Connect the power supply wires to the pressure
switch as shown in Figure 6.
Please go to Page 8 for startup preparations.
You have just completed the wiring for your pump.
