"I'VVO YEAR LIMITED
We suggest you take a few minutes to read the instructions
contained in this manual before installing and using your
pump. This will help you obtain the full benefits of the quality and convenience built into this equipment. It will also
help you avoid any needless service expense resulting from
causes beyond our control which naturally cannot be covered in our warranty.

WARRANTY
Provided that it is installed and operated according to the owner's manual instructions if this numn fails due to a
defect in material ok workmanship Within one year from the date of purchase, it will be repaid
orVreplaced free

During the second year from the purchase date, a free pump part will be supplied for a defective one. You must
pay the labor cost if you wish to have it installed.
Warranty service is available by returning this product to place of purchase

RULES FOR SAFE INSTALLATION
1. Read the Owners Manual and Rules for Safe Operation
and Installation Instructions carefully. Failure to follow
these Rules and Instructions could cause serious bodily
injury, and/or property damage.
IL 60179
AND OPERATION
6. Before installing or servicing your pump, BE CERTAIN
pump power source is disconnected.
7. Be sure your pump electrical circuit is properly grounded.
8. Complete pump and piping system MUST be protected
against below freezing temperature. Failure to do so could
cause severe damage and voids the Warranty.
2. Check your local electrical wiring codes before installation. If your local codes are not followed, your pump will
not work to its fuU rated capacity. If in doubt, contact
your local Power Company.
9. Make sure the line voltage and frequency of the electtical
circuit supply agree with the motor wiring. If motor is
dual voltage type, BE SURE it is wired correctly for your
power supply.
3. Be certain your pump installation meets all local plumbhag, pump and well codes.
4. While installing the pump, always keep the well covered
to prevent leaves and foreign matter from falling into the
well and contaminating the water and/or causing possible serious damage to the mechanical operation of the
pump.
10. The correct fusIng and wiring sizing is essential to proper
motor operation. Recollmaended fusing and wire size data
is in the manual.
5. Always test the well water for purity before using. Check
with local health department for testing procedure.

pumps have a built-in check valve. In a dug or cased well, a

Be sure the total lift from the pumping
water level to the
pump does not exceed 20 feet if the pump is over the well,
or less if the pump is offset from the well. Both figures are
for sea level - the maximum
lift at which the pump can operate satisfactorily,

rate of 1 foot per 1,000 feet of elevation;

drain cock on bottom
of
pump body and remove pressure switch tubing from
fitting on top of pump body. This will allow air to replace the water in the pump.

wipe clean the large O-Ring and also the small O-Ring,

16. This vdll insure a good tight seal.
Start pump. Pressure should build up rapidly as the jet and
pump prime. Pressure will be in excess of 60 pounds. If
this fails to happen, repeat 2 and 3 above.
5. Once unit has primed on pressure lxas stabilized,
slowly
open (turn counter-clockwise)
the pressure regulator and
water will begin to be pumped
into tank.
B. Lubricate O-Rings with petroleum
jelly for ease of assembly. Place large O-Ring in groove.
6.
C. Pump halves can now be slid together until they are
parallel and are as close together
as possible.
7.
8.
Continue to open pressure regulator until pressure falters
(becomes
erratic). At this point, close (turn clockwise)
the pressure
regulator
slightly until pressure
stabilizes.
Close faucets and allow pump to pressurize
the tank and
shut off.
D. BE SURE inside of clamp is clean. Place clamp on
pump halves and snug up. Alternately
tighten clamp
screw and tap around outside of clamp with a plastic
mallet. This vdU insure proper seating of O-Ring and
clamp.
To insure pump is operating
properly,
alternately
open
and close faucets in system. With faucets open, pressure
will drop until pressure
switch starts pump; and with
faucets
closed, pressure
will build up until pressure
switch shuts off pump.
E. Assemble

A GASEOUS
A good way of delivering gas-free water is to suspend a pipe,
closed at the bottom and open at the top, surrounding
the
suction pipe (Figure 14). Since the gases rise in the well casing, the water sucked down through the pipe and into the
suction pipe is free of gas. It is imperative
that this type of
well be vented to the outside of any enclosure.

TO HANDLE
In some localities well water contains gases which must be

as shown in Figure 14.

HOW TO AVOID OVER-PUMPING
A SHALLOW
WELL
In the section on Priming The Shallow
Well Pump, Page
10, the instructions
were to open the pressure
regulator
all
the way after the pump starts to deliver water. If you are
over-pumping
your well, however,
you can partially close
the pressure
regulator on your SEARS jet pump to increase
the pressure
and reduce the delivery.
