8. Slope horizontal lines up toward
pump a minimum of 1/4" per foot.
This will prevent trapping air in the
lines.
ELECTRICAL CONNECTIONS
The voltage of power supply must
match the voltage of the pump. Above
ground well pumps covered in this
manual have dual voltage motors pre-
set at the factory to 230 volts. The
motors can be converted to 115 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.

Connect the pump to a separate electri-

tain wiring for this
pump in accordance with the National
Electrical Code and all applicable local
codes.
The motor must be grounded by con-
necting a copper conductor to the
grounding screw provided within the
wiring compartment in the pressure
switch.
The field wiring compartment for the
jet pump is inside the pressure switch
housing. There is only one proper
ground screw on the unit. The screw is
located under the pressure switch
cover, painted green and is identified
as GRD. The ground connection must
be made to this terminal (Figure 7).

Refer to the wiring diagram located
under the cover of the pressure switch
(Figure 7).
To attach AC power to the switch,
loosen the screw holding the cover
onto the switch and remove the cover.
Loosen unused ground screw and
attach the exposed end of the ground
wire between the screw head and the
pressure switch body, then tighten.
Loosen the top two screws on the pres-
sure switch and retighten with the AC
power leads captured under the screw
heads. Reattach the pressure switch
cover and tighten the screw.
CONNECTION TO WATER SOURCE
230 V
DRIVEN WELL
1. Drive the point several feet below
the water table.
NOTE: A packer-type foot valve can be
installed in the well (Figure 8). This
type of foot valve allows the well pipe
to be filled with water when priming
and makes the inlet pipe much easier
to test for leaks. Follow the manufac-
turer's instructions when installing the
packer-type foot valve.

As an alternative, an in-line check valve

Do not use both a

significantly reduce the performance of
the pump.

1. Install a foot valve on the first sec-
tion of pipe (Figure 10).

2. Lower the pipe into the well.
3. Add pipe until the foot valve is 10
feet below the lowest anticipated
water level.
Leaking joints or couplings will allow
air to leak into the pipe and cause poor
pump operation. Make sure to use pipe
joint compound or Teflon ® tape on all
pipe connections.

CAUTION
!
at least 2 feet from
the bottom of the well so sand or sedi-
ment is not drawn into the system.
