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.

DO NOT ALLOW PUMP TO RUN DRY
Pump should not be allowed to run dry prior to shutting off.
To do so voids the warranty and could ruin the pump.
ELECTRICAL
ELECTRICAL CONNECTIONS
I_ikWARNINGIRisk of electric shock. This pump is sup-
plied with a grounding conductor and grounding-type
attachment plug. To reduce the risk of electric shock,
be certain that it is connected only to a properly
grounded, grounding-type receptacle.
The Sump 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 with an inter-
hal ground.
A separate 15 amp individual branch electrical circuit is rec-
ommended. 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
4A). A Circuit Analyzer will tell you by a pattern of fights if
the power, neutral, and ground wires are correctly con-
nected to your outlet. It can also be used to check other out-
lets in your home. A Circuit Analyzer is available in the Sears
Electrical Department.
Grounding Outlet
If your outlet is not grounded, install a copper wire (at least
14 gauge) from the outlet box, as shown in Figure 4B, 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 4C), 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, ff 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.
[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 if it starts
when you are working on it. Remove all power from
pump before attempting to work on it.
DO NOT attempt to repair a non-operational sump pump.
Take it to Sears for service by a qualified technician.
