protected against freezing.
Protect the pipe from damage from
swimmers and boats.
Install a screen
around the inlet pipe to
prevent the entrapment of swimmers.
SHALLOW WELL PUMP WITH
CONVENTIONAL STORAGE TANK
1. Install air volume control on tank.
2. Connect the copper tube from the air
volume control to the uppermost 1/8”
NPT opening on the side of pump. Be
sure the connections are tight. Leaking
can cause the pump not to prime.
3. Install a valve and an isolator hose
between the tank and the house
plumbing to aid in pump removal for
servicing and for reducing the noise
transmitted to the house through the
piping.
4. Provide a hose bib (faucet) at the
lowest point in the system to drain the
system for service or storage.
SHALLOW WELL PUMP WITH
PRECHARGED STORAGE TANK
1. Shut off the power to the pump.
2. Open the faucet nearest the tank and
allow all water to drain from the tank.
3. Measure the tank precharge at the valve
stem using a tire pressure gauge.
4. If necessary, precharge with an air
pump to 28 - 30 psi on 1/2, 3/4 and 1
HP pumps.
5. Slope the horizontal pipes upward
toward the pump to prevent trapping
air. If the horizontal distance exceeds
25 feet, see Chart 2 on page 3 for the
recommended pipe size.
Electrical
Risk of electrical
shock. This pump is
designed for indoor installation only.
The voltage of power supply must match
the voltage of the pump. The motors can be
converted to 115/230 volts by turning the
voltage selector to the desired voltage (See
Figure 6). Use a needle nose pliers to pull
the selector out approximately 1/4”, rotate
and then reinsert in correct position.
Select the proper size wire and fuse (Chart
3). Time delay fuses are recommended
over standard fuses for motor circuit
protection. All pump motors have built-in
