Electrical

Disconnect power before working on pump, motor, pressure switch, or wiring.
Motor Terminal Board Connections:
Your Motor Terminal Board (under the motor end cover)
looks like one of those shown below. If necessary, 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.

Switch. Match motor voltage to line voltage.
Hazardous voltage. Can shock, burn, or kill.
Connect ground wire before connecting power supply
wires. Use the wire size (including the ground wire) spec-
ified in the wiring chart. If possible, connect the pump to
a separate branch circuit with no other appliances on it.

Pressure Switch Connections:
Your Pressure Switch looks like one of those shown below.
Connect power supply as shown for your type of switch
and your supply voltage.
Motor wires connect here.
Power supply wires connect here.
230 Volt: Connect 2 hot wires (black and red)
here and cap the white (neutral) wire. It does
not matter which wire goes to which screw.
115 Volt: Connect one hot wire (black or red)
to one of these screws (it doesn't matter
which one). Connect the white (neutral) wire
to the other screw. Cap any remaining
black or red wires.
Clamp the power cable to prevent strain
on the terminal screws.
Connect the green (or bare copper) ground wire
to the green ground screw.
Motor wires connect here.
Power supply wires connect here.

Connect the green (or bare copper) ground wire
to the green ground screw.
Figure 6B:Wiring connections to Pressure Switch. Follow
instructions for your type of switch and your line voltage.
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
nameplate 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 6A.
The ground wire must be a solid copper wire at least as
large as the power supply wires.
