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 appliances on it.
WIRING CONNECTIONS
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 sin-
gle 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:
Step 1. Connect the ground wire first as shown in Figure 14. The ground
wire must be a solid copper wire at least as large as the power sup-
ply wires.
Step 2. There must be a solid metal connection between the pressure
switch and the motor for motor grounding protection. If the pres-
sure 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.
Step 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.
Step 4. Connect the power supply wires to the pressure switch as shown in
Figure 14.
You have just completed the wiring for your pump.
