INTRODUCTION
We suggest you take a few minutes to read the instructions
contained in this manual before installing and using your
pump. This viifi help you obtain the full benefits of the qual-
ity 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 cov-
eredinourwarranty.
RULES FOR SAFE INSTALLATION AND OPERATION
1. Read the Owners Manual and Rules for Safe Operation
and Installation Instructions careflifiy. Failure to follow
these Rules and Instructions could cause serious bodily
injury, and/or property damage.
2. Check your local electrical wiring codes before installa-
tion. ffyour local codes are not followed, your pump will
not work to its full rated capacity. If in doubt, contact
your local Power Company.
3. Be certain your pump installation meets all local plumb-
hag, 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 possi-
ble serious damage to the mechanical operation of the
pump.
5. Always test the well water for purity before using. Check
with local health department for testing procedure.
6. Before installing or servicing your pump, BE CERTAIN
pump power source is disconnected.
7. Be sure your pump electrical circuit is properly gruunded.
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.
9. Make sure the line voltage and frequency of the electrical
circuit supply agree with the motor wiring. If motor is
dual voltage type, BE SURE it is wired correctly for your
power supply.
10. The correct fusing and wiring sizing is essential to proper
motor operation. Recommended flWmg and v/ire size data
is in the manual.

INSTALLATION
NOTICE: Use Teflon tape supplied with the pump or Plasto-
Joint Stikl for making all pipe-thread connections to the
pump itself. To avoid stress-cracking, do not use pipe joint
compounds on the pump.
1. Wrap male pipe threads being attached to pump with one
or two layers of Teflon tape. Cover entire threaded por-
tion of pipe.
2. Do not overtighten threaded fittings in the plastic pump.
Be sure you do not try to tighten joint past thread stop in
pump port!
3. If leaks occur, remove fittings, clean off old tape, rewrap
with one to two layers of tape and remake the connec-
tion. If joint still leaks, replace the fittings (fittings may be
undersized).
4. Be sure to support all piping connected to the System.
MAJOR COMPONENTS AND WHAT
THEY DO
Tank and Air Volume Control
The tank serves two functions. It provides a reservoir of
water, some of which can be drawn through the house fix-
ture before the pump must start, and it maintains a cushion
of air under pressure.
When Captive Air + Tanks are used, no air volume control is
necessary. This tank contains a permanent pre-charge of air.
When a Standard Tank is used, an air volume control adds
air to the tank when it is needed. See instructions included
with Air Volume Control for details on installation and op-
eration.
Pressure Switch
The pressure switch provides for automatic operation.

Impeller, Jet and Pressure Regulator
The impeller of the pump rotates with the motor shaft, caus-
ing the water to fly out from its rim by centrifugal force. The
rotation of the impeller creates a vacuum which "puns" in
more water. Part of the water is diverted back to the jet
where it again passes through the nozzle and venturi - cre-
ating additional vacuum to draw in more water and deliver-
ing it at high pressure to the impeller.
In a deep well installation, the jet assembly is submerged
in the well because the vertical distance to the water level
exceeds the suction lift of the pump.
Adjustment of the pressure regulator causes the fight
amount of water to be diverted back to the jet for the most
efficient operation.
In a shallow well installation, the jet assembly is attached
directly to the pump because the vacuum created will pull
water to the pump.
The pressure regulator may be used to restrict the flow of
water in a shallow well system if the SEARS convertible
pump produces more water than the well can produce.
DEEP WELL PUMP INSTALLATION
(Figures I & 2, Page 4)
In a deep well installation, the jet assembly is submerged in
the well because the vertical distance to the water level ex-
ceeds the suction lift of the pump. A single pipe system must
be used in 2" and 3" wells. A double pipe system must be
used in 4" or larger wells.
Follow instructions packed with jet package for proper noz-
zle and venturi combination for your ptmaping depth.
DOUBLE PIPE JET
When a double pipe jet is selected, 2 pipes are used in the
well. One is the suction pipe, and the other, the pressure
pipe. Plastic pipe is ideal for double pipe installations, due
to its light weight mid easy installation.
Use 100 ponnd flexible plastic pipe on horizontal jet pumps.
TO INSTALL 4" DOUBLE PIPE JET
First, inspect jet to make sure no foreign matter has entered
the openings.
Be certain no foreign matter enters pipe openings while in-
stalling the unit.
Plastic Pipe Installations
1. Attach a foot valve (not furnished) to the jet with a short
nipple.
2. Before installing, be certain foot valve operates freely.
3. A special plastic pipe adapter is included with the jet
which screws into the 1-1/4" suction tapping over the
venturi.
4. Assemble a plastic pipe adapter (not furnished) into 1"
tapping in the jet body.
5. Use sufficient length of plastic pipe to place the jet 10-15
feet below the lowest drawdown water level. This is the
level to which the water in the well will drop while being
pumped continuously.
6. Tighten all hose clamps securely. A sanitary well seal is re-
quired on top of the well casing. Use steel nipples and el-
bows or specialized galvanized steel elbows to go through
the well seat. Use plastic pipe adapters where special el-
bows are not used.
