INTRODUCTION
Please read our instructions before you install and use your
new pump; this will help you obtain full value and good ser-
vice from it. It vdll also help you avoid needless service costs
that result from causes we cannot control and cannot cover
in our warranty.
GENERAL SAFETY INFORMATION
Carefully read and follow all safety instructions in this
manual or on pump.
_k 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!
_ warns about hazards that will cause serious
personal injury, death or major property damage if ignored.
A ]warns about hazards that will or can cause se-
]
WARNING
rious personal injury, death or major property damage if ig-
nored.
I& 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 ex-
ceeds 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
6, for information about common sump pump problems and
remedies.

To avoid risk of serious bodily injury and property dam-
age, read safety instructions carefully before installing
pump.
Follow local and/or national plumbing and electrical
codes when installing pump.
[&WARNING]To avoid fatal shocks, proceed as fol-
lows 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. Modern motors may operate at high temperatures.
B. Take extreme care when changing fuses. To re-
duce 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 an individual branch circuit with a
grounded outlet for cord plug.

this warning can result in personal injury and/or
property damage.
8. Release all pressure within the system before servicing
any component.
9. Drain water from the system before servicing.
10. Secure the discharge line before starting the pump. An un-
secured discharge line v(ill whip, possible causing per-
sonal injury and/or property damage.
11. Periodically inspect pump and system components. Perform
rouOne maintenance as required (See MAINTENANCE).
12. Provide a means of pressure relief for pumps whose dis-
charge line can be shut-off or obstructed.
13. Personal Safety:
a. Wear safety glasses at all times when working with
pumps.
b. Keep work area clean, uncluttered and properly
lighted - replace all unused tools and equipment.
c. Keep visitors at a safe distance from the work area.
d. Make workshop child-proof - with padlocks, master
svdtcbes, and by removing starter keys.
14. This equipment is only for use on 115 volt (single phase)
and is equipped with an approved 3-conductor cord and
3-prong, grounding-type plug.
[AWARNING]To reduce the risk of electric shock,
pull plug before servicing. This pump has not been
investigated for use in swimming pool areas. This
pump is supplied with a grounding conductor and
grounding-type attachment plug. Be certain that it
is connected only to a properly grounded ground-
ing-type receptacle,
Where a 2-prong wall receptacle is encountered, it
must be replaced with a properly grounded 3-prong
receptacle installed in accordance with the National
Electrical Code and local codes and ordinances.
15. Protect electrical cord from sharp objects, hot surfaces,
oil, and chemicals. Avoid kinking the cord. Replace or re-
pair damaged or worn cords immediately.
16. Do not handle a pump or pump motor with wet hands or
when standing on a wet or damp surface, or in water.
[AWARNING_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 depart-
ment for instructions. Remove pump and repair or
replace. Failure to follow this warning can result in
fatal electrical shock.
ADDITIONAL INSTALLATION
MATERIALS (Purchase Separately)
Sump Pump Hose Kit, SEARS Stock No. 27909, containing
24' (7.3M) of 1-1/4" flexible plastic pipe, 1-1/4" plastic
adapter and stainless steel clamp. We recommend a Check
Valve, SEARS Stock No. 2789 or 2792.
THE SUMP
Locate sump at lowest place in basement or drained area.
Floor drains or drain tiles can also be tiled into sump.
Minimum sump size is 10" (254mm) in diameter by 20" deep
(508ram). Periodically inspect pump, system components,
and sump for debris and foreign objects. Keep sump free
from all refuse. Perform routine maintenance as required.
Use a sump cover to exclude refuse from sump. Consult
local code for cover specifications.

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. Do not install the pump on clay,
earth, or sand surface.
INSTALLATION /ELECTRICAL
A_UTION ] 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.
Hose Kit No. 27909 can be used as the discharge pipe. 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 bacldlow into sump when pump shuts off,
install a Check Valve, SEARS Stock No. 2789, in threaded dis-
charge port of pump. A SEARS No. 2789 Check Valve is con-
structed with an anti-airlock hole. If you use a SEARS No. 2792
or any other check valve, drill a 1/8" hole in the discharge pipe
just above the pump discharge port and below the Check
Valve to prevent pump from airlocking.
Make sure the air-bleed hole is down inside the sump so that
it does not run water on the basement floor when the pump
is running.
DO NOT ALLOW PUMP TO RUN DRY].
Be sure to leave at least 5" (127mm) of water above
pump base plate when pump stops. Running pump
dry could ruin the pump and will void the warranty.
ELECTRICAL CONNECTIONS
The Sttmp Pump has a 3-prong electric plug. The third prong
is used to ground the purnp to prevent possible fatal shock.
The third prong should never be removed. Your electrical
outlet should be the 3-prong, polarized type with an inter-
nal ground.
An individual branch 15 amp electrical circuit is recom-
mended. DO NOT USE AN EXTENSION CORD.
Testing for Ground
For your safety, check your outlet for ground using an
Underwriters Laboratory Listed Circuit Analyzer (Figure 2).
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 acopper wire, at least
14 gauge (2mm_), from the outlet box, as shown in Figure
3, 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 continu-
ity is interrupted by plastic, rubber, or other electrical insu-
lators; 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 4), with a length of No. 4 wire clamped securely
at both ends.

Automatic Thermal Overload Protection
This pump motor has a buih-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 dan-
ger point.
I&WANNING ] 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 required
to power this pump motor. Any additional loads, such as lights,
must be added to the listed load and the generator sized ac-
cordingly. Generators are available at all Sears Stores.
