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 automatic

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 the screen
and shield from the bottom of the pump and make sure
that the impeller turns freely. Remove any debris ob-
structing impeller. If pump still does not operate cor-
rectly, 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 25 feet (7.6M) or less.

d. Be sure discharge pipe is not plugged or frozen.

SWITCH REPLACEMENT

NOTICE:

Float must be able to swing through its complete

arc without interference from sidewall of sump, plumbing
or any other object.

1. Remove pump power cord from switch plug.
2. Remove tether clamp screw and slide cord from clamp.
3. Insert new cord in tether clamp. Put the clamp at the

same distance from the float that it was on the old switch.

4. Tighten tether clamp screw.
5. Check sump pump operation by filling sump with water

and observing operation through one complete cycle.

Failure to check installation with water

in sump can lead to improper operation, premature
pump failure and flooding.
