[AWARNIN_ Hazardous voltage. Can shock, burn, or kill.
Connect ground wire before connecting power supply
wires. Use the wire size (including the ground wire) speci-
fied in the wiring chart, if possible, connect the pump to a sep-
arate branchcircuit with no other appliances on it.
LAWARNING] Explosion hazard. Do not ground to agas sup-
ply line.
WIRING CONNECTIONS
[AWARNINGI Fire hazard. Incorrect voltage can cause a fire or
m
seriously damage the motor and voids the warranty. The supply
voltage must be within ± 101o 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.
Connection Procedure:
l. Connect the ground wire first as shown in Figure 4. 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 grotmd 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 4.
