{_'WARNINGI Hazardous voltage. Can shock, born, 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 pnmp to a separate branch circtdt with no other appll- ances on it.

[,_WARNING] Explosion 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 name*

plate 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 single voltage motors.

Install, ground, wire, and maintain your pump in compli-

ance 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 grotmd 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 pro-

tection. 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 thc 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, 9,$"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.
