INSTALLATION WIRING DIAGRAMS -
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 local codes. Use a ground wire at least as
large as the wires supplying power to motor.
Permanently close all unused openings in this
and other equipment.
Disconnect power to control box before
working on or around control box, pipes, cable,
pump, or motor.
Install control box vertically with top side up
and out of direct sunlight.
Wire control box as shown on Pages 5 and 6.
Pump will not operate without control box, and
deluxe boxes require a switch or a jumper lead
between 'SW' and 'L2' terminals. Operation
without control box will burn out motor.
Installation must meet United States National
Electrical Code, Canadian Electrical Code, and
local codes for all wiring (as applicable).
If main overload trips, look for:
1. Shorted Capacitor
2. Voltage Problems
3. Overloaded or locked pump.
