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

Carefully read and follow all safety instructions in this
manual or on pump.

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 ff ignored.

['_ WAFININGIwarns about hazards that will or can cause se-

rious personal injury, death or major property damage if ig-

nored.

It, CAUTIONIwarn s 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 surnp 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 opacity, 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
sttmp pnmp or a DC backup sump pinup. See "Service', Page

6, for information about common sump pump problems and
remedies.

1. To avoid risk of serious bodily injury and property dam-

age, read safety instructions carefully before installing
pump.

2. Follow local and/or national plumbing and electrical

codes when installing pump.

3. [&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 tempera-

HIFeS.

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

Ground Fault Circuit Interrupter (GFCD protected
grounded outlet for cord plug.

SAFETY / INSTALLATION

4. Never rim pump dry. To do so can damage internal

parts, overheat the pump (which can cause burns to peo-
ple handling or servicing the pump), and will void the

warranty_.

5. DO NOT attempt to oil the pump motor. A special oil has

been put into the motor housing at the factory; use of any
other oll will void the warranty and could damage the

pump.

6. This pump is recommended for use in permanent instal-
lations only. This pump has not been invenstigated for use

in swimming pool areas.

7. Know the pump application, limitations, and potential
hazards. Not for use with salt water or brine.

[_'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.

8. Release aU 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 will whip, possible causing per-

sonal injury and/or property damage.

11. Periodically inspect pump and system components. Perform
routine 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.

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.

oil, and chemicals. Avoid kinking the cord. Replace or re-
pair damaged or worn cords immediately.
