GROUNDING INSTRUCTIONS
GROUNDING INSTRUCTIONS
To prevent electric shock and death from incorrect grounding wire connection,
read and follow these instructions:
Check with a qualified electrician if you are in doubt as to whether the outlet is properly
grounded. Do not modify the power cord plug provided with the tool. Never remove the
grounding prong from the plug. Do not use the tool if the power cord or plug is damaged.
If damaged, have it repaired by a service facility before use. If the plug will not fit the
outlet, have a proper outlet installed by a qualified electrician.
125 V~ 3-Prong Plug and Outlet
(for up to 125 V~ and up to 15 A)
Grounding Pin
1. Tools marked with “Grounding Required” have a three-prong cord and three-wire
grounding plug. The plug must be connected to a properly grounded outlet. If the
tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of electric
shock.
2. The grounding prong in the plug is connected through the green wire inside the cord
to the grounding system in the tool. The green wire in the cord must be the only
wire connected to the tool’s grounding system and must never be attached to an
electrically “live” terminal.
3. The tool must be plugged into an appropriate outlet, properly installed and grounded
in accordance with all codes and ordinances. The plug and outlet should look like
those in the preceding illustration.
4. This pump is intended for use on a circuit that has an outlet that looks like the one
illustrated above. The pump has a grounding plug that looks like the plug illustrated
above.
5. The outlet must be properly installed and grounded in accordance with all codes and
ordinances.
6. Do not use extension cords with this pump.

INSTALLATION INSTRUCTIONS
The well motor pump must be installed in a stationary position with a fixed pipeline
and a steady water supply.
Please Note!
1. Remove the screw from the front of the unit to connect the power to the heater.
2. The pump must be installed with an automatic float 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 120 V~, 60 Hz safety socket.
2. Make sure that the socket is sufficiently secured and is in excellent condition.
3. When the plug is inserted into the socket the pump will be on standby.
Installation Considerations
This pump is designed for use as a well pump.
INSTALLATION INSTRUCTIONS
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
confident in your ability to properly and safely install this pump, have a qualified technician perform
the installation.
d. The water to be pumped must be clean and must be free of sand and grit which will damage the
pump and void the warranty.
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 certified 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.

INSTALLATION INSTRUCTIONS
1. The illustration below shows an example of a proper
shallow well pump installation. The total suction lift
(vertical well lift and length of off-set line) must not
exceed the maximum suction lift.
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.
NOTE:
• This pump is intended for
shallow well application only
and is not intended to be used
as a booster pump.
• For optimal performance, install
the pump as close to the well
head as possible
CAUTION:
DO NOT insert fittings into the intake hole farther than 1/2" (12.7 mm); this can DAMAGE the pump, diminish pump
functions, and/or STOP water flow.
Pump Setup Example
4. Intake and discharge pipes must be at least 1" (2.5 cm) 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 as shown in the above illustration.
Systems with longer off-set lines should use larger diameter pipe to improve efficiency.
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 filled
with water. Do not allow water to contact the pump's housing.
7. Keep the head, the height that the pump discharge must push water before discharge,
to a minimum. The vertical well lift and off-set line length added together must be
smaller than the maximum suction lift, and the head must be smaller than the
maximum delivery height, to have flow at output. Effective flow decreases to 0 GPH as
the delivery height reaches its maximum.
8. For your protection, the power outlet used should have a Ground Fault Circuit
Interrupter (GFCI). Have it installed by a qualified 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.

OPERATING INSTRUCTIONS
OPERATING INSTRUCTIONS
1. The compression has a rubber bladder inside. This bladder must be pumped up
to 23 PSI of air at all times. Use a bicycle pump (not included) to inflate the
bladder. On the end of the compression tank, opposite the inlet, 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 ensure 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 first time, prime it as follows:
a. Fill the suction pipe and pump body through the priming inlet.
b. Close the inlet after verifying that there are no leaks.
c. Open the spigots, faucets and/or taps on the delivery pipe so that air can be
release from the suction cycle.
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 120 V~, 60 Hz.
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 onto standby mode until the pressure falls below its starting
pressure.
