ELECTRICAL CONNECTIONS
The Sump Pump has a 3-prong electric plug. The third
prong is used to ground the pump to prevent possible fatal
shock. The third prong should never be removed. Your
electrical outlet should be the 3-prong, polarized type with
an internal ground.
An individual branch 15 amp electrical circuit is
recommended. DO NOT USE AN EXTENSION CORD.
TESTING FOR GROUND
For your safety, check your outlet for ground using an
Underwriters Laboratory Listed Circuit Analyzer (Figure
3A). A Circuit Analyzer will tell you by a pattern of lights
if the power, neutral, and ground wires are correctly
connected to your outlet. It can also be used to check other
outlets in your home. A Circuit Analyzer is available in the
Sears Electrical Department.

GROUNDING OUTLET
If your outlet is not grounded, install a copper wire, at
least 14 gauge (2mm²), from the outlet box, as shown in
Figure 3B, to a metal cold water pipe. Use ground clamp
on pipe.

The cold water pipe you use as a ground must have metal
continuity to electrical ground. If continuity is interrupted
by plastic, rubber, or other electrical insulators; such as
hoses, fittings, washers or gaskets (including water meter
or pump), a metal bypass must be used. Any electrically
insulated connector should be jumped (as shown in Figure
3C), with a length of No. 4 wire clamped securely at both
ends.

AUTOMATIC THERMAL OVERLOAD PROTECTION
This pump motor has a built-in automatic thermal overload
protector. If the motor overheats, the protector will open
and cut off power to the motor before the heat damages
it internally. The overload will reset automatically and the
pump will restart after the pump cools down below the
danger point.
Risk of electric shock. Can shock, burn or
kill. DO NOT attempt to work on the pump or motor if the
overload seems to have tripped. The motor may restart
without warning at any time. You could be injured and the
pump damaged if it starts when you are working on it.
DO NOT attempt to repair a non-operational sump pump.
Take it to Sears for service by a qualified technician.
GENERATOR SIZING
Below is the minimum Engine-Generator Watt rating
required to power this pump motor. Any additional loads,
such as lights, must be added to the listed load and the
generator sized accordingly. Generators are available at all
Sears Stores.
