Electrical
Risk of electric shock . 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 appliances on it.
Risk of explosion . Do not ground to a gas supply line.
Wiring Connections
Risk of fire . 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 may be set for 115 V or 230 V. If necessary,
reset the motor to the desired 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.
You have just completed the wiring for your pump.
