ELECTRICAL / MAINTENANCE
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 inter-
nal ground.
A separate 15 amp branch 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 (2mm
2
), from the outlet box, as shown in Figure
3B, to a metal cold water pipe. Use ground clamp on pipe.
IMPORTANT:
The cold water pipe you use as a ground
must have metal continuity to electrical ground. If continu-
ity is interrupted by plastic, rubber, or other electrical insu-
lators; 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 dan-
ger point.
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 re-
quired to power this pump motor. Any additional loads,
such as lights, must be added to the listed load and the gen-
erator sized accordingly. Generators are available at all Sears
Stores.

MAINTENANCE
Make certain that the pump is unplugged
before attempting to service or remove any compo-
nent.
1. The motor in the unit is sealed in oil. No additional lubri-
cation is necessary.
2.
IMPORTANT:
Disassembly of the motor assembly will
void the warranty. It might also cause internal leakage and
damage to the unit. If repairs are required, return the
pump to the dealer from whom it was purchased.
3. Inlet screen should be kept clean and free of all foreign
objects.
Pump Cleaning
NOTICE:
Attempting to disassemble motor will void the
warranty.
1. Disconnect power cord from electrical outlet before
working on pump. The volute screen and shield may be
removed to replace impeller or clean pump of mud or de-
bris.
2. Remove 8 screws from volute plate and clean impeller.
Replace paper gasket if it is damaged.
To Reassemble:
Attach volute plate to volute with 8 screws.
