NOTE:
1. Maximum wire lengths shown maintain motor voltage at 95% of
service entrance voltage, running at maximum nameplate
amperes. If service entrance voltage will be at least motor name-
plate voltage under normal load conditions, 50% additional length
is permissable for all sizes.
2. Sizes given are for copper wire. For aluminum wire go two sizes
larger (i.e., if table lists #12 (3mm
aluminum wire.)
INSTALLATION WIRING INSTRUCTIONS
Single Phase, 3 Wire
Hazardous voltage. Can shock, burn, or kill.
Ground control box, all metal plumbing, and motor frame with copper
wire in compliance with Canadian Electrical Code or National Electrical
Code and local codes. Use ground wire at least as large as the wires
supplying power to motor.
At well head, connect ground wire to grounding terminal that meets
Canadian Electrical Code or National Electrical Code requirements that
apply. For more information, contact local code officials.
Permanently close all unused openings in this and other equipment.
Disconnect power before working on or around control box, pipes, cable,
pump, or motor.
NOTICE: Install control box vertically on wall with top side up.
3-Wire pumps have three power supply wires (Red/Black/Yellow) and
one ground wire (Green).
Attempting to operate 3 wire pump without a control box will burn out the
motor.
Installations must include circuit and component protection in compli-
ance with U.S. National Electrical Code or Canadian Electrical Code,
Part 1.
If main overload trips, look for:
1. Shorted Capacitor
2. Voltage Problems
3. Overload or locked pump.
NOTICE: Use only control box specified for your pump. Make sure
motor and control box match (Table 4). FAILURE TO DO SO WILL
VOID WARRANTY.

For motors of 1-1/2 HP and above, use magnetic
starter to avoid damage to pressure switch. Consult factory for
wiring information.
