Installation
The well motor pump must be installed in a stationary
position with a xed pipeline and a steady water supply.
Please note!
1. Do not install the pump by suspending
it unsupported from its delivery pipe.
The pump must be placed on the bottom of the shaft.
2. The pump must be installed with an automatic
oat switch (not included) to prevent running dry.
Power Supply
1. The pump is equipped with a shock-proof plug
according to regulations. The pump is designed
to be connected to 120V~, 60Hz safety socket.
2. Make sure that the socket is sufciently
secured and is in excellent condition.
3. When the plug is inserted into the socket
the pump will be on standby.
WARNING! If the power cord or plug is damaged,
do not use the pump. The power cord or plug
may only be repaired by a certied electrician.

WARNING! TO PREVENT SERIOUS INJURY
FROM ELECTRIC SHOCK:
Install indoors or in weather-proof well house only.
This Pump is non-submersible.
Do not plug in the power cord when wet
or standing on damp or wet ground.
Do not plug in the power cord until instructed to do so.
NOTE:
a. ONLY pump clean water.
b. Additional components (such as valves and pipes)
may be required for installation, but not included.
c. Installation requires skilled workmanship
and compliance with local building codes.
Ifyouarenotcondentinyourabilityto
properly and safely install this pump, have a
qualiedtechnicianperformtheinstallation.
d. The water to be pumped must be clean and
must be free of sand and grit, which would
damage the pump and void the warranty.

1. The illustration below shows an example of a proper
shallow well pump installation. The total suction lift
(vertical well lift + length of off-set line) must
not exceed Maximum Well Depth.

Figure C: Pump Setup Example
Note: This pump is intended for shallow well application
only and is not intended to be used as a booster pump.
Note: For optimal performance, install the pump
as close to the well head as possible.
2. Install a Foot Valve at the bottom of
the suction pipe. The Foot Valve must be
under the Pumping Water Level, the level that
the water falls to when the pump operates.
3. Install a sterile Well Seal at the top of the suction
pipe to keep the well clean. Protect from
rust inside a frost-proof enclosure.
4. Intake and discharge pipes must
be at least 1 IN. in diameter.
5. Lay an off-set line from the well to the structure
the pump will be installed in. The off-set line should
slope slightly towards the well (see Figure C).
Systems with longer off-set lines should use
larger diameter pipe to improve efciency.
6. Install the pump on a rigid, level, dry platform.
This platform must provide a solid, level surface
that is capable of supporting the weight of
the pump and attached piping lled with water.
Do not allow water to contact the pump’s housing.
CAUTION: DO NOT INSERT ttings into the Intake
Hole farther than 1/2 IN.; this can DAMAGE the Pump,
diminish Pump functions, and/or STOP water ow.
7. Keep the Head, the height that the pump discharge
must push water before discharge, to a minimum.
The Vertical Well Lift, Off-set Line Length, and Head
added together must be less than Maximum Lift to
have ow at output. Effective ow decreases to
0 GPH as Maximum Lift reaches its maximum.
8. For your protection, the power outlet used should
have a Ground Fault Circuit Interrupter (GFCI).
Have it installed by a qualied electrician.
Keep power line away from water.
9. The inlet and discharge lines should not be
wedged or stressed in a way that puts strain
on the pump. Do not support the pump
with the inlet or discharge lines.

Operation
1. Compression Tank has a rubber bladder inside.
This bladder must be pumped up to 28 PSI of air at
all times. Use a bicycle pump (not included) to inate
the bladder. On the end of the Compression Tank
opposite the side with the Pressure Meter, is an air
valve located under a cover. Remove the cover over
the air valve and periodically monitor this air valve
with an air pressure gauge to insure that the rubber
bladder maintains the required air pressure.
2. Make sure the intake pipe is fully
submerged before continuing.
3. Beforestartingthepumpforthersttime,
primeitbyllingitwithcleanwater
through the Priming Inlet.
4. This is a self-starting pump that uses
a pressure switch. Once the power cord is
connected, the pump can start at any time.
Do not handle or perform maintenance on
the pump if the power cord is plugged in.
5. After reading these instructions,
consider the following points
before starting the pump:
a. Verify that the delivery pipe is properly connected.
b. Verify that the electrical connection
is 120V~, 60Hz.
c. Verify that the electrical socket
is in good condition.
d. Verify that water and moisture cannot
get near the power supply socket.
e. Verify that the pump is installed so
as to prevent running dry.
6. To begin pumping, plug in the power cord.
When the line is pressurized, the pump
will go to standby mode until the pressure
falls below its starting pressure.

Maintenance
TO PREVENT SERIOUS INJURY FROM
ACCIDENTAL OPERATION:
Unplug the Pump from its electrical outlet
before performing any inspection,
maintenance, or cleaning procedures.
1. Clean the inlet screen on the intake port
regularly to remove accumulated debris.
2. Wipe the pump clean with a soft, damp cloth
with soapy water. Do not use solvents.
Do not get the electrical components wet.
3. Drain water from pump before storage by
disconnecting the water lines and turning the Pump
upside down. If storing the pump for a long time,
store it in a dry location, and apply a light layer of
oil to the metal parts prior to storage, to inhibit rust.
Do not expose to freezing temperatures.
4. After storage, check the Impeller to make
sure it turns easily and is not oxidized.
Troubleshooting
Problem Cause Solution
The pump won’t start 1. No power.
2. Pressure switch disconnected.
3. Thermal Protection cut out.
4. Blocked impeller.
1. Check connections, and breaker/fuse.
2. Check gauge.
3. Allow pump to cool.
4. Free the impeller.
The pump operates
but it won’t
discharge water
1. Pump not primed.
2. Lift height exceeded.
3. Inlet tube not submerged.
4. Air in suction pipe.
5. Inlet screen clogged.
1. Prime pump.
2. Reduce lift height.
3. Submerge the inlet.
4. Check pipe and seals.
5. Clean screen.
Only a low volume
of water ows
1. Inlet pipe is too small.
2. Liquid is too dirty.
3. Lifting height exceeded.
4. Tank’s rubber bladder under-inated.
5. Piping corroded, causing friction.
1. Increase pipe diameter.
2. Clean screen frequently.
3. Reduce lifting height.
4. Inate to 28 PSI.
5. Replace piping, with plastic where possible.
Motor overheats often 1. Extension cord too long or
wire size too small.
2. Pump cycling too often.
1. Eliminate use of extension cord or
use shorter/heavier gauge cord.
2. Cut-in and cut-out pressure may be set
too close together. Have the pressure
switch adjusted by a qualied technician.
Pump/motor
cycles rapidly
Cut-in and cut-out pressure
may be set too closely.
Have the pressure switch adjusted
by a qualied technician.
Tank bladder will
not hold pressure
1. Air inlet valve is leaking.
2. Bladder is broken.
1. Check air tank for leaks using soapy
water and replace bladder if needed.
2. Replace bladder.
Water pumps
intermittently
Water level is being drawn below foot valve. Lower foot valve.
Pump will not
hold prime
1. Foot/check valve not installed
in suction line.
2. Foot/check valve leaks water back to well.
1. Install foot and check valve in suction line.
2. Replace foot/check valve.
Follow all safety precautions whenever diagnosing or servicing the pump.
Disconnect power supply before service.
Do not disassemble the pump or motor as this will damage the water seals.

air is purged after initial setup.
2. Leak in suction side of pump system.
3. Well is gaseous.
4. Water level below suction
inlet of foot valve.
1. Temporary self-remedying issue.
2. Check for and x leaks.
