the well to be filled with water when
priming and makes the inlet pipe much
easier to test for leaks. Follow the
manufacturer's instructions when
installing the packer type foot valve.
As an alternative, an in-line check valve
can be used with a driven well (Figure
3, Illustration C). The pipe between the
check valve and the water level will
always be under a vacuum.
Leaking joints or couplings will allow
air to leak into the pipe and cause
abnormal pump operation. Make sure
to use pipe joint compound on all male
pipe threads.

INSTALLATION (FIGURE 12)
1. Install a foot valve on inlet pipe and
lower into water.
The foot valve
should be at least
18" from the bottom of the well or
sand or sediment could be drawn into
the system.
NOTE: When a lake is used as a water
supply, make sure the inlet pipe is deep
enough to be submerged at all times.
Slope the horizontal piping upward
toward the pump to prevent trapping
air. The pipe must be removed during
winter months or protected against
freezing.
Protect the pipe from damage from
swimmers and boats.
Install a screen
around the inlet
pipe to prevent the entrapment of swim-
mers.

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
thrugh the piping.
4. Provide a hose bib (faucet) at the
lowest point in the system to drain
the system for service or storage.

exceeds 25 feet, see Chart 2 for the
recommended pipe size.

Figure 7 - Electrical Connections
Select the proper size wire and fuse
(Chart 3). Time delay fuses are recom-
mended over standard fuses for motor
circuit protection. All pump motors
have built-in automatic overload pro-
tection that will prevent damage to the
motor due to overheating.
Do not connect to
electric power sup-
ply until unit is permanently grounded.
Connect ground wire to approved ground
then connect terminal provided.
A metal underground water pipe or
well casing at least 10 feet long makes
the best ground electrode. If plastic
pipe or insulated fittings are used, run
a wire directly to the metal well casing
or use a ground electrode furnished by
the power company.
There is only one proper ground termi-
nal on the unit. The terminal(s) is
located under the pressure switch
cover, is painted green and is identified
as GRD. The ground connection must
be made at this terminal (Figure 7a or
