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 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.
CAUTION: DO NOT INSERT fittings into the Intake
Hole farther than 1/2 IN.; this can DAMAGE the Pump,
diminish Pump functions, and/or STOP water flow.
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 Delivery Height to have flow at
output. Effective flow decreases to 0 GPH as
Maximum 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.
Operation
1. The Compression Tank 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 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 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 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.
