SAFETY WARNINGS AND
PRECAUTIONS
WARNING Read all safety warnings
and instructions. Failure to follow the
warnings and instructions may result
in electric shock, re and/or serious
injury.
Save all warnings and instructions
for future reference.
Read all instructions before use!
Keep work area clean1. . Cluttered areas
invite injuries.
Observe work area conditions2. . Do not
expose this pump to rain or submerge
in water. Keep work area well lighted.
Do not use electrically powered pumps
in the presence of ammable gases or
liquids.
Keep children away3. . Children must
never be allowed in the work area. Do
not let them handle Pump.
Use the right pump for the job4. . Do
not attempt to force a small Pump to
do the work of a larger industrial Pump.
There are certain applications for which
this Pump was designed. It will do the
job better and more safely at the rate for
which it was intended. Do not modify
this Pump and do not use this Pump for
a purpose for which it was not intended.

Use eye and ear protection6. . Wear
ANSI-approved impact safety goggles
and ear protection.
Do not overreach7. . Keep proper footing
and balance at all times. Do not reach
over or across running machines.
Maintain Pump with care8. . Keep Pump
clean for better and safer performance.
Inspect pump cords periodically; If dam-
aged, have them repaired by a qualied
technician.

not in use.
Stay alert10. . Watch what you are doing,
use common sense. Do not install Pump
when you are tired.
Check for damaged parts11. . Before us-
ing Pump, any part that appears dam-
aged should be carefully checked to
determine that it will operate properly
and perform its intended function. Check
for alignment and binding of moving
parts; any broken parts or mounting x-
tures; and any other condition that may
affect proper operation. Any part that is
damaged should be properly repaired or
replaced by a qualied technician.
Replacement parts and accessories12. .

TABLE A
USE PROPER EXTENSION CORD. 14.
Make sure your extension cord is in
good condition. When using an exten-
sion cord, be sure to use one heavy
enough to carry the current your prod-
uct will draw. An undersized cord will
cause a drop in line voltage resulting in
loss of power and overheating. Table A
shows the correct size to use depending
on cord length and nameplate ampere
rating. If in doubt, use the next heavier
gauge. The smaller the gauge number,
the heavier the cord.
Maintenance15. . For your safety, mainte-
nance should be performed regularly by
a qualied technician.
Pump clean water only.16. Do not use the
pump for any other application.
People with pacemakers should consult 17.
their physician(s) before use. Electro-
magnetic elds in close proximity to
heart pacemaker could cause pacemak-
er interference or pacemaker failure.
The brass components of this product 18.
contain lead, a chemical known to the
State of California to cause birth defects
(or other reproductive harm). (California
Health & Safety code § 25249.5, et seq.)
Do not operate this pump if the power 19.
cord or electrical components are
damaged or the seals are compro-
mised. Do not plug in the power cord

when wet or standing on damp or wet
ground. Exercise caution when work-
ing with electrical equipment in the
presence of water to maintain your
personal insulation to avoid shock.
Use GFCI (Ground Fault Circuit Inter-
rupter) outlets when using this pump.
WARNING: The brass components 20.
of this product contain lead, a chemi-
cal known to the State of California to

WARNING: Handling the cord on this 21.
product will expose you to lead, a chemi-
cal known to the State of California to
cause cancer, and birth defects or other
reproductive harm. Wash hands after
handling.

WARNING! TO PREVENT SERIOUS INJURY
FROM ELECTRIC SHOCK:
Install indoors or in weather-proof well
house only. This Pump is non-submers-
ible.
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: ONLY pump clean water.
Note: Additional components (such as valves
and pipes) may be required for installa-
tion, but not included.
Note: Installation requires skilled workman-
ship and compliance with local building
codes. If you are not condent in your
ability to properly and safely install
this pump, have a qualied technician
perform the installation.
The water to be pumped must be clean 1.
and must be free of sand and grit, which
would damage the pump and void the
warranty.

example of a proper shallow well pump
installation. The total suction lift (vertical
well lift + length of off-set line) must not
exceed the Maximum Suction Lift listed
on the Specications chart.
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 pos-
sible.
Install a Foot Valve at the bottom of the 3.
suction pipe. The Foot Valve must be
under the Pumping Water Level, the
level that the water falls to when the
pump operates.
Install a sterile Well Seal at the top of 4.
the suction pipe to keep the well clean.
Protect from rust inside a frost-proof
enclosure.
REV 05l, 07g, 09d, 09e
Page 6For technical questions, please call 1-800-444-3353.SKU 47906
Intake and discharge pipes must be at 5.
least 1” in diameter.
Lay an off-set line from the well to the 6.
structure the pump will be installed in.
The off-set line should slope slightly
towards the well (see Fig. 2). Systems
with longer off-set lines should use larger
diameter pipe to improve efciency.
Install the pump on a rigid, level, dry 7.
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”; this can
DAMAGE the Pump, diminish Pump
functions, and/or STOP water ow.
Keep the Head, the height that the 8.
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 Max.
Total Head to have ow at output.
Effective ow decreases to 0 GPH as
Total Head reaches its maximum.
For your protection, the power outlet 9.
used should have a Ground Fault Circuit
Interrupter (GFCI). Have it installed by
a qualied electrician. Keep power line
away from water.
The inlet and discharge lines should not 10.
be wedged or stressed in a way that puts
strain on the pump. Do not support the
pump with the inlet and discharge lines.

OPERATION
Compression Tank has a rubber bladder 1.
inside. This bladder must be pumped
up to 26-29 PSI of air at all times. Use a
bicycle pump (not included) to inate 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.
Make sure the intake pipe is fully 2.
submerged before continuing.
Before starting the pump for the rst 3.
time, prime it by pouring clean water
into the Priming Inlet.
This is a self-starting pump that uses a 4.
pressure switch. Once the power cord
is connected and the unit is switched on,
the pump can start at any time. Do not
handle or perform maintenance on the
pump if the power cord is plugged in.
To begin pumping, plug in the power 5.
cord and turn the switch on. When the
line is pressurized, the pump will go to
standby mode until the pressure falls
below its starting pressure.

REV 06c; 07g; 07l; 08l; 09d
MAINTENANCE
WARNING! Disconnect pump from power
source before maintenance.
Clean the inlet screen on the intake port 1.
regularly to remove accumulated debris.
Wipe the pump clean with a soft, damp 2.
cloth with soapy water. Do not use sol-
vents. Do not get the electrical compo-
nents wet.
Drain water from pump before storage 3.
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 tem-
peratures.
After storage, check the Impeller to make 4.
sure it turns easily and is not oxidized.
Note: Turn off the Switch and unplug the
pump when performing maintenance.
