WIRING CONNECTIONS
[_.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: Dual-voltage motors are factory wired for 230 volts. If nec-
essary, 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 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.

-Power supply wires connect here.
230 Volt: Connect 2 hotwires (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). Connec_the white (neutral) wire
to the other screw. Cap any remaining
• black or red wires.
prevent strain
on the terminal screws.
- Connect the green (or bare copper) ground wire
to the green ground screw.

FIGURE 6 - Pressure switch wiring
Connection Procedure:
1. Connect the ground wire first as shown in Figure 9. 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 (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 6.
5. Reinstall the pressure switch cover.
