Carefully read and follow all safety instructions in this manual
or on pump.
This is the safety alert symbol. When you see this symbol
on your pump or in this manual, look for one of the
following signal words and be alert to the potential for personal
injury!
DANGER warns about hazards that will cause
serious personal injury, death or major property damage if
ignored.
WARNING warns about hazards that can cause
serious personal injury, death or major property damage if
ignored.
CAUTION warns about hazards that will or can
cause minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which are
important but not related to hazards.
Electrically powered sump pumps normally give many years of
trouble-free service when correctly installed, maintained, and
used. However, unusual circumstances (interruption of power to
the pump, dirt/debris in the sump, flooding that exceeds the
pump’s capacity, electrical or mechanical failure in the pump,
etc.) may prevent your pump from functioning normally. To
prevent possible water damage due to flooding, consult your
local Sears store about installing a secondary sump pump or a DC
backup sump pump. See “Service”, Page 5, for information about
common sump pump problems and remedies.
1. Read these Instructions and Safety Rules carefully. Failure
to follow them could cause serious bodily injury and/or
property damage.
2. Check your local Electrical and Plumbing Codes before
installing pump. You must comply with their rules.
3. During operation, the pump and surrounding area is in
water. Risk of electric shock. Proceed as follows if
pump needs servicing:
A. Disconnect power to pump outlet box before pulling
pump cord plug! After plug is pulled, let pump cool for
20 minutes before attempting to work on it.
B. Take extreme care when changing fuses. To reduce the
chance of fatal electrical shocks, DO NOT stand in
water or put your finger in the fuse socket.
C. Ground the electrical outlet box.
D. Use only a grounded outlet for cord plug.
4. Never run pump dry. To do so can damage internal parts,
overheat the pump (which can cause burns to people
handling or servicing the pump), and will void the
warranty!
FIRE HAZARD – Do not store or rest
objects on or near motor or switch linkage. Keep all
flammable objects or liquids away from motor.
5. This pump is recommended for use in permanent
installations only.

GENERAL SAFETY INFORMATION

THE SUMP
The sump should be located at the lowest place in the
basement or area to be drained. Floor drains from other
areas in the basement may be tiled into the sump. Drain
tile around a house foundation can also be tiled into the
sump, effectively removing water and relieving pressure
from this area. A suitable sump can be a 20" or 24" (500-
600mm) sewer tile. The minimum size is 12" (305mm) for
automatic float switch.
A sump cover is desirable to exclude refuse from the
sump. Consult local code for sump cover specifications.
Inspect pump, system components, and sump monthly for
debris and foreign objects. Keep sump free from all refuse.
Perform routine maintenance as required.
PUMP INSTALLATION
Set the pump on the bottom of the sump, making sure that
it sits solidly and is level. Be sure there is enough space
around the pump to allow the switch free movement as
the sump water level changes.
Risk of flooding. If a flexible discharge hose
is used, pump may move around in sump when motor
starts. If it moves far enough so that the switch hits the
side of the sump, the switch may stick and prevent pump
from starting. Make sure that pump is secured so that it
cannot walk around in sump.
Run the discharge pipe to the nearest sewer outlet or other
point of disposal. Use the most direct route and the fewest
turns and elbows possible.
Use Teflon tape to seal threads in plastic pipe. Hand
tighten only.
NOTE: To avoid water in the discharge pipe running back
into the sump when the pump shuts off, we recommend
installing a Check Valve in the discharge tapping of the
pump. Be sure arrow on check valve body points away
from the pump.
MECHANICAL ROD AND FLOAT
SWITCH INSTALLATION
The rod and float assembly consists of a steel rod, a plastic
float, and four (4) rubber bushing stops.
The assembly must be attached to the switch arm of the
switch on the motor as follows:
See Figure 2 for ( ) numbers.
1. Push one rubber bushing stop (1) to middle of steel
rod.
2. With rod in vertical position, slide bottom end of rod
down thru hole in solid end of float marked TOP.
NOTE: When completely assembled, end of float
marked TOP must face up towards the motor.

3. Push one rubber bushing stop (3) up on rod under
float about 5" (125mm) from end of rod.
4. Push one rubber bushing stop (4) down from top end
of rod about 3" (76mm).
5. Insert bottom end of rod in hole in rod guide on base
of drainer.
6. Lift top end of rod up thru hole in switch arm and
push last rubber bushing stop (6) down on rod about
1" (25mm).
7. Slide rubber bushing stop (4) under switch arm up on
rod so there is about 1/2" (13mm) distance between
the two top bushings. This will allow for free
movement of the switch arm between the bushings.
8. Lift the rod up and down to check that the switch will
click and the arm does not bind on the rubber
bushings.
9. When switch arm is in the up position, the bottom end
of the steel rod should be about 1" (25mm) below the
rod guide.
The switch unit operates as follows:
1. When the sump is dry, the float rests on the bottom
rubber bushing stop. Its weight holds the drainer
switch off.
2. When the water raises in the sump, the float moves up
to the next bushing stop. The buoyancy will raise the
float rod allowing the switch arm to raise and turn the
drainer switch on.
3. When the water is pumped out of the sump, the float
drops down on the bottom bushing stop. Again, the
weight of the float will allow the rod and switch arm
to lower and turn the drainer switch off.
DO NOT ALLOW PUMP TO RUN DRY
Pump should not be allowed to run dry prior to shutting
off. To do so voids the warranty and could ruin the pump.
If necessary, adjust the switch so this will not happen.
ELECTRICAL CONNECTIONS
Risk of electric shock. 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.
A separate 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 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 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.
IMPORTANT: The cold water pipe you use as a ground
must have metal continuity to electrical ground. If con-
tinuity 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 over-
load 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 automa-
tically 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 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
generator sized accordingly. Generators are available at
all Sears Stores.

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. Be sure nothing interferes with action of float
switch.
d. If a, b, and c 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 it from
sump. Remove the plate 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 18' (5.5M) or less.
d. Be sure discharge pipe is not plugged or frozen.
LUBRICATION
Motor has been lubricated at the factory. It does not
require additional oil. Bronze bearing in volute housing is
oil impregnated. It does not require additional oil.
