3. Insure tank is secured to the floor or
base.
4. Bolt pump to the floor or the
mounting bracket on tank.
5. Set air pressure in tank to desired
level. an air valve is located on
the side and will accept a standard
fitting from a bicycle pump or air
line.
6. Install a valve and an isolator hose
between the tank and the house
plumbing. this will reduce the noise
level of the pump system and aid in
servicing.
7. Provide a hose bib (faucet) at the
lowest point in the system to drain
the system for service or storage.
8. Slope horizontal lines up toward
pump a minimum of 1/4" per foot.
this will prevent trapping air in the
lines.

the voltage of power supply must
match the voltage of the pump. above
ground well pumps covered in this
manual have dual voltage motors
preset at the factory to 115 volts. the
motors can be converted to 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.
Connect the pump to a separate
electrical circuit with a dedicated
circuit breaker. Refer to the electrical
specifications in the Wiring Chart

pump in accordance with the National
Electrical Code and all applicable local
codes.
the motor must be grounded by
connecting 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 pressure
switch, first ensure power has been
disconnected to the circuit. loosen
the screw holding the cover onto the
pressure 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
pressure switch and retighten with the
aC power leads captured under the
screw heads. Reattach the pressure
switch cover and tighten the screw.

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 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
