[,_.WARNING I
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. [f possible, connect the
pump to a separate branch circuit with no other appliances on it.
[AWARNING] Expiosion hazard. Do not ground to a gas supply line.
Wiring Connections
[_i_WARNING] 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: The motor is factory wired for 115 volts. [f necessary, reconnect
the motor for 230 volts, as shown in Figures 12A, 12B, and 12C. Do not
attempt to operate the pump as it comes from the factory on 230 volts.
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 tile ground wire first as shown in Figure 1 1. The ground
wire must be a solid copper wire at least as large as the power
supply wires.
Step 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 motoc 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.
Step 4.
Connect the ground wire to a grounded lead in a service panel,
to a metal underground water pipe, to a metal weil casing at least
ten feet (3M) long, or to a ground electrode provided by the power
company or the hydro authority.
Connect the power supply wires to the pressure switch as shown in
Figure 1 1.
You have just completed the wiring for your pump.
