• This pump is provided with a means for grounding. To

reduce the risk of electrical shock from contact with

adjacent metal parts, bond supply box to the pump-

motor-grounding means and to all metal parts acces-

sible at the tank, including metal discharge pipes, and

the like, by means of:

1. An equipment grounding conductor at least the size

of the power cable conductors to the pump.

2. A clamp, a weld or both if necessary, secured to the

equipment grounding terminal, or the grounding

conductor on the pump housing. The equipment

grounding lead, if one is provided, is the conductor

that has an outer surface of insulation that is green

with or without one or more yellow stripes.-UL 778

MOTOR CABLE INSTALLATIONS

• Prepare the motor cable by stripping off ½" (13 mm) at

the end of each conductor’s insulation.

NOTICE: FOLLOW THE SPLICE KIT

MANUFACTURER’S INSTRUCTIONS.

• Where cables are spliced or connected to the motor

leads, splices MUST be water tight. Commercially

available potting or heat shrinking kits may be used, if

allowed by local or federal regulations.

• To ensure proper sealing, immerse splice in a metal

container filled with water for ten minutes, then take a

resistance reading between the metal container and the

cable conductor. Resistance should read 2 megohms or

higher. Redo splice as required.

• Two wire motors do not require a control box.

Standard units are not designed for use in

swimming pools, open bodies of water,

hazardous liquids, or where flammable

gases exist. These fluids and gases may

be present in contaminant areas. Tank or

wetwell must be vented per local codes.
Only pumps specifically Listed for Class

1, Division 1 are allowable in hazardous

liquids and where flammable gases may

exist. See specific pump catalog bulletins

or pump nameplate for all agency list-

ings.
Disconnect and lockout electrical power

before installing or servicing any electrical

equipment. Many pumps are equipped

with automatic thermal overload pro-

tection which may allow an overheated

pump to restart unexpectedly.

PIPING

• System piping MUST conform to all local and national

plumbing codes and practices.

WIRING AND GROUNDING

Important notice: Read Safety Instructions before pro-

ceeding with any wiring.

Use only stranded copper wire

to pump/motor and ground.

The ground wire must be at

least as large as the power sup-

ply wires. Wires should be color

coded for ease of maintenance

and troubleshooting.

Install wire and ground according to the National

Electrical Code, as well as all local, state and pro-

vincial codes.
Install an all leg disconnect switch where required

by code.
Disconnect and lockout electrical power before

performing any service or installation.
The electrical supply voltage and phase must

match all equipment requirements.
Incorrect voltage or phase can cause fire, motor

and control damage, and voids the warranty.
All splices must be waterproof. If using splice kits

follow manufacturer’s instructions.

Seal all controls from gases present which

may damage electrical components.

FAILURE TO PERMANENTLY

GROUND THE PUMP, MOTOR AND

CONTROLS BEFORE CONNECTING

TO ELECTRICAL POWER CAN

CAUSE SHOCK, BURNS OR DEATH.

Reduced risk of electrical shock during

operation of this pump requires the provi-

sions of acceptable grounding.
