LIMITATION OF LIABILITY

RULES FOR SAFE INSTALLATION AND OPERATION

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

_This is the safety, alert symbol. When you see this sym-

bol on your pump or in this manual, h)ok for one of the

following signal words and he alert to the potemial for personal
injury!

I warns about hazards that will cause serious per-

sonal injury, death or major property damage ff ignored.

[ _.WARNING ]warns about hazards that will or can cause seri-

ous personal injury, death or major property damage if ignored.

& cAuTioN-,: warnsL. _ - " about hazards that will or can cause

minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which are im-

portant but not related to hazards.

Electrically powered stamp 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 exceeds the
pump's capacity, electrical or mechanical failure in the pump,

etc.) may prevent your pump from functioning normally. To pre
vent 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 5, for information

about common sump pump problems and remedies.

1. To avoid risk nf serious bodily injury and property damage,
read safety instructions carefully before installing pump.

2. Follow local and/or national plumbing and electrical codes

when installing pump

3. _*v_nn._uj TO avoid fatal shocks, proceed as follows
if pump needs servicing:

&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.

Modem motors are designed to operate at high tempera-
tures.

B. Take extreme care when changing fuses. To reduce

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 (GFCI) protected grounded
outlet for cord plug.

4. Never run pump dry. To do so can damage internal parts,
overheat the pump (which can cause burns to people han-
dling 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 oil will void the warranty and could damage the pump.

6. This pump is recommended for use in permanent installa-

tions only. Pump water only with this pump.

ADDITIONAL INSTALLATION
HATERIALS

Sump/Utility Pump Hose Kit, SEARS Stock No. 27909, con-
taining 24' (7.3M) of 1-1/4" flexible plastic pipe, a 1-1/4" plas-

tic adapter and a stainless steel clamp.
Check Valve, SEARS Stock No. 2789.

INSTALLATION

THE SUMP

The sump should be located at the lowest place in the base-

ment or area to be drained. Floor drains from other areas in
the basement may be tiled into the sump. Drain tile around
a house foundation can also be tiled into the sump, effec-

tively removing water and relieving pressure frorn this area.

A suitable sump can be a 20" or 24" (500_10mm) sewer tile.

The minimum size is 12" (305mm) in diameter for Models

390.304552 and 390.304612; 10" (254mm) for Model

390.304692.

A sump cover is desirable to exclude refuse from the sump.

Consult local code for sump cover specifications.
NOTICE: Periodically inspect pump, system components,

and sump for debris and foreign objects. Keep sump free of
all refuse. Perform routine maintenance as required.

PUMP INSTALLATION

Set the pump on the bottom of the sump, making sure that
is 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. Pump should not be installed on

clay, earth, or sand surfaces.

[& CAUTION}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 includes 1-1/4" flexible plastic pipe for

the discharge pipe. Run discharge pipe to the nearest sewer
outlet or other point of disposal. Use the most direct route
and the fewest turns and elbows possible. Make sure that
pump cannot move around in sump pit.

Use teflon tape to seal threads in plastic pipe. Hand tighten
only.

NOTE: To avoid backflow into sump when pump shuts off,
install a Check Valve, SEARS Stock No. 2789, in threaded dis-
charge port of pump. Be sure arrow on check valve body
points away from the pump. This Sears check valve is
equipped with an air bleed hole to prevent airlocking pump.
If using any other check valve, drill 1/8" (3.2mm) hole in
dishcharge pipe just above pump body but below check
valve to prevent air locks.

FLOAT SWITCH
INSTALLATION AND OPERATION

(Models 390.304552 and 390.304612;

For Model 390.304692, see Page 7)

The automatic float switch is factory mounted on the pump
and preset for a pumping range of approximately 7". Tether

length is factory preset at 3-1/2" (89mm) (see Figure 3). Do
not change tether length.

Be sure automatic float can swing freely through its entire
arc without interference from pump, piping, sump wall or

any other object.

When sump is dry, the watertight automatic float switch is

hanging in a downward position and the pump is off.

As water comes into the sump, the automatic float switch

rises to an upward position and the pump starts.
Water will continue to be pumped until the float switch is

hanging in the downward position again, when pump will
stop.

IAWARNING]Risk of electric shock. Before installation,

check your local electrical codes. To avoid personal injury
when servicing your pump, be sure that the power is dis-
connected from both the pump and the float switch.

To check operation, fill sump with water and observe oper-
ation through one complete cycle.
