Splice this ground wire to a copper conductor
that matches motor wire size specified in
Table III. See Page 5 for wire splicing
instructions.
Permanently ground pump, motor and control
box before connecting power cable to power
supply. Connect ground wire to approved
ground first and then connect to equipment
being installed.
Do not ground to a gas supply line.
Fire and electrical shock hazard. If
using a drop wire larger than No. 10 (5.5mm
2
)
(for example, No. 8 (8.4mm
2
) wire) between
pump and control box, run wire to a separate
junction box. Connect junction box to control
box with a No. 10 (5.5mm
2
) or smaller wire
(depending on amp rating of pump – see
Table III).
For more information, contact your local code
officials.
WIRING CONNECTIONS:
All wiring must meet National Electrical Code or
Canadian Electrical Code and local code
requirements.
Use only copper wire when making connections
to pump and control box.
To avoid over-heating wire and excessive voltage
drop at motor, be sure that wire size is at least as
large as size listed in Table III for your horse-
power pump and length of wire run.
NOTICE:
When built-in overheating protection
is not
provided, use with an approved overload
equipped motor control that matches motor
input in full load amps. Select or adjust overload
element(s) in accordance with control instruc-
tions. When built-in overheating protection
is
provided, use with an approved motor control
that matches motor input in full load amperes.

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.
