Installation 4
Installation Wiring Diagrams
Risk of electric shock . 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 in gauge as the wires supplying
power to the motor.
Single Phase, 3 Wire
Permanently close all unused electrical control
openings in this and other equipment enclosures.
Disconnect power to control box before working
on or around control box, pipes, cable, pump,
or motor.
To be sure that starting relay will function and
that overload will not “nuisance trip”, install
control box vertically with top side up.
Wire control box as shown in Figure 1. A 3-wire
pump will not operate without a control box
and will burn out a 3-wire 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.
NOTICE Use only control box specified for your
pump. Make sure motor and control box match
(Table 3). Failure to do so will void warranty.
