INSTALLATION
[_&WARNING]Do not use power cord to lift motor. Al-
ways use handle,
NOTICE: Do not use this pump in ponds containing plants
or fish.
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 v4th an inter-
nal ground.
A separate 15 amp GFCI branch electrical circuit is recom-
mended. 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 pat-
tern of llghrs ffthe power, neutral, and ground wires are cor-
rectly connected to your oudet. It can also be used to check
other outlets in your home. A Circuit Analyzer is available in
the Sears Electrical Department.
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 sereen 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 pro- Figure A
vided vdth pump.
b. To install with rigid pipe, use plastic pipe. Wrap thread
with Teflon tape or use Plasto Joint Stik*. Screw pipe
into pump hand tight +1 - 1-1/2 turns.
NOTICE: Do not try to disassemble pump farther than re-
moving inlet screen. Any evidence of tampering v_ill void
warranty.
3. Power Supply: Pump is designed for 115V, 60 Hz opera-
tion and requires a circuit of 15 amperes or more capac-
ity. 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 (2mm z) size is
suggested, with larger sizes for runs over 25 ft (7M). For Figure B
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.
[_'WARNING_The pump motor is equipped with
automatic resetting thermal protector and may re-
start unexpectedly. Protector tripping is indication
of motor overloading as a result of operating pump
at low heads (low discharge restriction), exces-
sively high or low voltage, inadequate wiring, in-
correct motor connections, or a defective motor or
pumtp.

Grounding Outlet
If your outlet is not grounded, install a copper wire, at least
14 gauge (2mmZ), 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 insula-
tors; 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.
Automatic Thermal Overload Protection
This pump motor has a built-'m automatic thermal overload
protector. If the motor overheats, the protector wiU 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.
[AWARNING ]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 ff 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 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.

OPERATION
[a_'WARNINGJRJsk of electric shock. Do not handle
pump or pump motor with wet hands or when stand-
hag 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 oper-
ate pump unless it is in at ]east 3/16" (4.75mm) of water
as seal may be damaged if allowed to run dry.
2. Motor is equipped with automatic reset thermal pro-
tector. If temperautre in motor should rise unduly, switch
v_tll 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 re-
peatedly, pump should be checked as to cause of diffi-
culty. Low voltage, long extension cords, clogged
impeller, very low head or liR, etc., could cause cycling.
3. Pump w'dl pump water down to 3/16" (4.75mm); this
means that it v_ill 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.
[AWARNING 1Risk of electric shock. Before attempt-
ing to check why unit has stopped operating, dis-
connect power fi'om unit. Do not handle pump with
wet hands or when standing on wet or damp sur-
faces, or in water. Failure to follow precaution can
result in personal injury and/or property damage.
Airlocks
When a pump airlocks, it rims but does not move any water.
An airlock wiU 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-aiflock hole with a paper clip or
piece of wire, and restart pump.
IMPORTANT: This hole allows the pump to start priming
wir21in 15 seconds in as little as 1/2" of water. NEWER restart
pump in less than 1/2" of water. Leakage from the anti-air-
lock hole is normal.

HAINTENANCE
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 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
waiTanty.
1. Disconnect power cord from electrical outlet before work-
ing on pump. The volute screen and shield may be re-
moved 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 pttmp, 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 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.
