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 appli-
ances on it. 

Explosion hazard.

Do not ground to a gas

supply line.

WIRING CONNECTIONS

Fire hazard.

Incorrect voltage can cause a

fire or seriously damage the motor and voids the warranty.
The supply voltage must be within ±10% of the motor name-
plate voltage.

NOTICE: 

Dual-voltage motors are factory wired for 230

volts. If necessary, reconnect the motor for 115 volts, as
shown. Do not alter the wiring in single voltage motors.
Install, ground, wire, and maintain your pump in compli-
ance 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 4. 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 pro-
tection. 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 (3M) 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 4.

Figure 4: Motor wiring connections through Pressure Switch. Match motor voltage to line voltage.

Your Motor Terminal Board (under the motor end cover)
and Pressure Switch look like one of those shown below.
Convert to 115 Volts as shown. Do not change motor wiring

if line voltage is 230 Volts or if you have a single voltage
motor. Connect power supply as shown for your type of
switch and your supply voltage.
