SERVICE

General

Risk of electric shock. When servicing

pump always disconnect power to electrical outlet
and remove pump electric cord from outlet. Inspect
sump pump and system components monthly. Keep
free of debris and foreign objects.

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 oper-
ate 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 feet  or less.

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