General Safety Information

14.Protect electrical cord from sharp objects, hot surfaces,
oil,and chemicals.Avoid kinking the cord. Replace or
repair damaged or worn cords immediately.
15.Do not touch an operating motor. Modern motors can
operate at high temperatures.
16.Do not handle a pump or pump motor with wet hands
or when standing on a wet or damp surface, or in water.
Risk of electric shock. If your basement
has water or moisture on the floor, do not walk on
wet area until all power has been turned off. If
shut-off box is in basement, call the electric
company to shut-off service to the house, or call
your local fire department for instructions. Remove
pump and repair or replace. Failure to follow this
warning can result in fatal electrical shock.
Installation
Do not use power cord to lift motor.
Always use handle.
NOTICE: Do not use this pump in ponds containing
plants or fish.
1. Pump should be located and should rest on level
solid foundation.Do not suspend pump by means of
discharge pipe or power cord. Keep pump inlet screen
clear.
2. Thread outlet pipe into pump body carefully to avoid
stripping or crossing threads.
a. To install with 3/4”garden hose,install adapter
provided with pump.
b. To install with rigid pipe, use plastic pipe.Wrap
thread with 1Teflon™ tape or use 2Plasto Joint Stik®.
Screw pipe into pump hand tight +1 - 1-1/2 turns.
NOTICE: Do not try to disassemble pump farther than
removing inlet screen.Any evidence of tampering will
void warranty.
3. Power Supply: Pump is designed for 115V, 60 Hz
operation and requires a circuit of 15 amperes or more
capacity.It is supplied with a 3-wire cord set with
grounding-type plug for use in a 3-wire, grounded outlet.
3 wire extension cord,of at least 14 AWG (2mm2) size
is suggested, with larger sizes for runs over 25 ft (7M).
For safety,pump should always be electrically grounded
to a suitable electrical ground such as a grounded
water pipe or a properly grounded metallic raceway, or
ground wire system. Do not cut off the round grounding
prong.
The pump motor is equipped with
automatic resetting thermal protector and may
restart unexpectedly. Protector tripping is
indication of motor overloading as a result of
operating pump at low heads (low discharge
restriction), excessively high or low voltage,
inadequate wiring, incorrect motor connections,
or a defective motor or pump.
Electrical Connections
The 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.
A separate 15 amp GFCI branch electrical circuit is
recommended. DO NOT USE AN EXTENSION CORD.
Testing for Ground
For your safety, check your outlet for ground using a
Circuit Analyzer. (Figure A).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 B,
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
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 C), with a length of No. 4
wire clamped securely at both ends.
AutomaticThermal 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.
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 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.

Operation
Risk of electric shock. Do not handle
pump or pump motor with wet hands or when
standing on wet or damp surface, or in water.
NOTICE: Do not use this pump in ponds containing
plants or fish.
1. Shaft seal depends on water for lubrication. Do not
operate pump unless it is in at least 3/16”(4.75mm) of
water as seal may be damaged if allowed to run dry.
2. Motor is equipped with automatic reset thermal
protector. If temperature in motor should rise unduly,
switch will cut off all power before damage can be
done to motor.When motor has cooled sufficiently,
switch will reset automatically and restart motor. If
protector trips repeatedly, pump should be checked as
to cause of difficulty. Low voltage,long extension cords,
clogged impeller, very low head or lift, etc., could cause
cycling.
3. Pump will pump water down to 3/16”(4.75mm); this
means that it will not remove all water. If unit has
been operating and suddenly no water comes out of
discharge hose,shut off unit immediately.Water level is
probably very low and unit has broken prime. Use mop
or squeegee to remove remaining water.
Risk of electric shock. Before
attempting to check why unit has stopped
operating, disconnect power from unit. Do not
handle pump with wet hands or when standing
on wet or damp surfaces, or in water. Failure to
follow precaution can result in personal injury
and/or property damage.
Airlocks
When a pump airlocks, it runs but does not move any
water.An airlock will cause the pump to overheat and fail.
This pump has an anti-airlock hole in the bottom of the
pump body (see Page 7). If you suspect an airlock, unplug
the pump, clean out the anti-airlock hole with a paper clip
or piece of wire, and restart pump.
NOTICE: This hole allows the pump to start priming
within 15 seconds in as little as 1/2”of water. NEVER
restart pump in less than 1/2”of water. Leakage from the
anti-airlock hole is normal.

Maintenance
Make certain that the pump is unplugged before
attempting to service or remove any component.
1. The motor in the unit is sealed in oil. No additional
lubrication 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
debris.
Service
General
Risk of electric shock. When servicing
pump always disconnect power to electrical outlet
and remove pump electric cord from outlet.
1. If pump does not operate:
a. Check for loose plug at electric outlet.
b. Check for blown fuses or tripped circuit breakers at
fuse box/circuit breaker box.
c. If a and b above check OK, plug in a light that you
know works.If it lights,take your pump to Sears
for service. If it doesn’t light,the electrical circuit is
faulty;consult a licensed electrician.
2. Pump starts,but blows fuses/trips circuit breakers:
After disconnecting power to pump, remove the
screen and shield from the bottom of the pump and
make sure that the impeller turns freely. Remove any
debris obstructing impeller. If pump still does not
operate correctly,return it to your nearest Sears Service
Department for repairs.
3. Pump runs, but does not empty sump:
a. Clean pump intake screen.
b. Water may be entering sump faster than the pump
can discharge it.
c. Be sure vertical distance from pump discharge outlet
to discharge pipe outlet is 22-1/2 feet (6.9M) or less.
d. Be sure discharge pipe is not plugged or frozen.
e. Unplug pump. Clean out anti-airlock hole.Restart
pump.
