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 will also help you avoid needless service costs

that result from causes we cannot control and cannot cover

in our warranty.

GENERAL SAFETY INFORMATION

NOTICE: This unit is not designed for applications involving

salt water or brine! Use with salt water or brine will void

wan'anty.

1. Know the pump application, limitations, and potential

hazards.

_WARNING]DO not use in explosive atmospheres.

Pump water only with this pump. Failure to follow

this warning can result in personal injury and/or

property damage.

2. Disconnect power before servicing.

3. Release all pressure within the system before servicing

any componeht.

4. Drain water from the system before servicing.

5. Secure the discharge line before startlng the pump. An un-

secured discharge line will whip, possibly causing per-

sonal injury and/or property damage.

6. Check hoses for weak or worn condition before each use,

making ce_ain that all connections are secure.

7. Periodically inspect pump and system components.

Perform routine maintenance as required (See

MAINTENANCE, Page 4).

8. Provide a means of pressure relief for pumps whose dis-

charge line can be shut-off or obstructed.

9. Personal Safety:

pumps.

b. Keep work area clean, uncluttered and properly

lighted - replace aLlunused tools and equipment.

c. Keep visitors at a safe distance from the work area.

d. Make workshop child-proof - with padlocks, master

switches, and by removing starter keys.

10.When wiring an electrically driven pump, follow elec-

trical and safety codes, as well as the most recent National

Electrical Code.

11.This equipment is onty for use on 115 volt (single

phase) and is equipped with an approved 3-con-

ductor 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 agrounding 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.

12.All wiring should be performed by a qualified electrician.

l?,.Make certain that the power source conforms to the

requirements of your equipment.

pair damaged or worn cords immediately.

15. Do not touch an operating motor. Modern motors can op-

erate at high temperatures.

16. Do not handle a pump or pump motor with wet hands or

when standing on a wet or damp surface, or in water.

IAWARNINGI 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.

INSTALLATION

[A WARNINGIDo 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 shock2

The third prong should never be removed. Your electrical

outlet should be the 3-prong, polarized type with 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 lights ff the power, neutral, and ground wires are cor-

rectly connected to your outlet. It can also be used to check

other outlets in your home. ACircuit 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 screen 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 with pump.

b. To install with rigid pipe, use plastic pipe. Wrap thread

with Teflon tape or use Plasto Joint Stik*. Screw pipe

into ptmlp hand fight +1 -1-1/2 turns.

NOTICE: Do not try to disassemble pump farther than re-

moving inlet screen. Any evidence of tampering will void

warranty.

3. Power Supply: Pump is designed for l15V, 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 (2ram _) size is

suggested, with larger sizes for rims 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.

[AWARNING ]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

pump.

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-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.

IAWARNING'_ DO NOT attempt to work on the pump or

motor if the overload seems to have tripped. The

motor may restart without wm'ulng 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 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

[_'WARNING-]Risk of electric shock. Do not handle

pump or pump motor with wet hands or when stand-

ing 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 least 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 temperature in motor should rise unduly, switch

will 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 lift, etc., could cause cycling.

3. Pump will pump water down to 3/16" (4.75mm); this

means that it will 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 remainhag water.

I_,WARNING ] Risk of electric shock. Before attempt-

ing to check why unit has stopped operating, dis-

connect power from 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 runs 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-airlock hole with a paper clip or

piece of wire, and restart pump.

IMPORTANT: This hole allows the pump to start priming

within 15 seconds in as little as 1/2" of water. NEVER restart

pump in less than 1/2" of water. Leakage from the anti-air-

lock hole is normal.

MAINTENANCE

Make certain that the pump is unplugged before

attempting to service or remove any component.

1. The motor in the unit is sealed in off. 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

warranty.

1. Disconnect power cord from electricaloutlet before work-

hag on pump. The volute screen and shield may be re-

moved to replace impeller or clean pump of mud or

debris.

SERVICE

General

['AWARNING_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. Pmnp 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 20 feet (6M) or less for Model

390.2645, and 22-1/2 feet (6.9M) or less for Model

390.2655.

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

e. Unplug pump. Clean out anti-airlock hole. Restart

pump.
