Installation (Continued)
Make sure the pump has adequate
ventilation. The surrounding
temperature should not exceed 100˚F
(38˚C) or nuisance tripping of thermal
overload protector on the motor may
occur.
PUMP PIPING INSTALLATION
Use new pipe for best results. Iron,
copper or PVC pipe may be used.
To avoid strain on the pump when
using iron or copper pipe, provide
independent supports for both suction
and discharge piping near the pump.
Minimize use of elbows and fittings
to reduce friction loss. Refer to the
friction loss chart (page 5) for specific
information. Increase diameter of
suction or discharge piping if length is
over 50 feet.

SUCTION PIPING
Install foot valve
or strainer screen
over intake of suction piping.
Never use pipe smaller than 1-1/4”
diameter for suction piping. Keep
suction pipe free of air leaks. For
horizontal runs, lay pipe from the water
source so the upward slope is at least
1/2" per foot. This eliminates trapped
air. The threaded inlet of the pump is
1-1/4" NPT.
Do not install
suction piping near
swimming areas.

CONVENTIONAL TANK (SEE FIGURES 3
& 4)
A conventional water tank stores
water and pressurized air in the same
compartment. When full, the tank
contains approximately 2/3 water and
1/3 compressed air. This type of tank
requires an air volume control, which
automatically replaces air lost due to
leak or absorption into the water.
1. Shut off power to pump. Disconnect
and lock out power source.
2. Drain the tank. Opening faucet
nearest tank is recommended.
3. Insure tank is secured to the floor or
base.
4. Bolt pump to the floor or the
mounting bracket on tank.
5. Install air volume control on tank.
6. Connect the tube from the air
volume control to the front 1/8"
NPT opening on the side of the
pump. Connections must be tight.
Leaks will cause the pump not to
prime and/or the tank to become
waterlogged.
7. 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.
8. Provide a hose bib (faucet) at the
lowest point in the system to drain
the system for service or storage.

PRE-CHARGED TANK (SEE FIGURE 5)
A pre-charged water tank stores air
and water in separate compartments,
separated by a flexible bladder. The
barrier prevents the air from being
absorbed into the water. The bladder
design also allows the water to be
acted on by higher pressures for longer
periods than a conventional tank.
Pre-charged tanks have roughly twice
the usable capacity of a conventional
tank with equal volume. The air
pressure in a pre-charged tank must be
checked periodically to insure it is at an
acceptable level (See Maintenance).
1. Shut off power to pump. Disconnect
and lock out power source.
2. Drain the tank. Open faucet nearest
the tank.

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
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

Install and maintain
wiring for this
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

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 plumbers seal tape
on all pipe connections.
Locate foot valve at
least 2 feet from
the bottom of the well so sand or
sediment is NOT drawn into the system.
4. After proper depth is reached, install
a well seal or pitless adapter to
support the pipe.
5. Slope the horizontal pipe upward
toward the pump to eliminate
trapping air.

Operation
PRIMING PUMP
Do NOT run pump
dry. Fill with water
before starting motor. Damage to pump
seals WILL result and void warranty.
After pump installation is complete, the
pump must be primed.
1. Remove the priming plug.
2. Fill pump and piping completely full
of water.
3. Replace the priming plug.
4. Open faucet to vent system.
5. Start the motor. Water will be
pumped within a few minutes. If
pump does not deliver water within
5 minutes, shut off motor and return
to step 1.
6. Let the system operate for several
minutes to flush out the pipes.
7. Close the faucet and allow pump
to build pressure in the tank. When
pressure reaches cut-out setting, the
motor will stop.
The system is now operating and will
cycle on demand.
If the pump does not operate after
repeated attempts, check the following:
1. Vertical distance of pump to water
must not exceed 25 feet.
2. Suction piping must be air tight.
3. Be sure valves are open if used in
discharge or suction piping.
NEVER run the
or clogged discharge. The water inside
the pump COULD boil and damage the
pump.
The use of a foot valve is strongly
recommended. This allows the suction
line to be filled during the priming
process, greatly decreasing priming
times.
pump with a closed
Maintenance
Disconnect power supply
and release all pressure from
system before attempting
to install, service, relocate, or perform
any maintenance. Lock the power
disconnect in the open/off position.
Tag the power disconnect to prevent
unexpected application of power.
Serious injury or death COULD result.
Maintain adequate ventilation for the
pump motor. The motor bearings are
permanently lubricated at the factory.
Additional lubrication is not required.
DRAINING PUMP
Drain openings are provided on all
models. To drain the pump:
1. Disconnect power to the pump
2. Remove the drain fitting and
priming plug.
3. Drain all piping to a point below the
frost line.
DRAINING TANK
Conventional tanks can be drained by
opening an outlet at the lowest point
in the system. Remove a plug or the air
volume control to vent the tank.
Pre-charged tanks force virtually all
of the water from the tank when the
system pressure is released. No draining
is necessary.
WATER-LOGGED TANKS
CONVENTIONAL TANKS
When a tank system has an inadequate
ratio of air and water, the pump will
start and stop often and erratically.
1. Disconnect electrical power to
pump.
2. Open the lowest faucet in the
system to release all pressure.
3. Prime the pump.
4. Reconnect power.
As the pump refills the tank, the air
volume control supplies the tank with
the correct air to water ratio. The pump
will then shut off at desired pressure.
If tank water-logs again, examine air
volume control and replace if necessary.

Maintenance (Continued)
PRE-CHARGED TANKS
If a pre-charged tank becomes water-
logged, the bladder is probably leaking
or broken.
1. Test the tank by depressing the air
valve. The valve will discharge water
if the bladder is broken.
2. If bladder is broken, replace tank.
Once a tank bladder is ruptured, the
tank should be replaced. Repairing
the bladder is not recommended, and
may cause further problems such as:
repeated water-logging, debris in pipes
and clogged discharge in tank.
AIR PRESSURE CHECK FOR PRECHARGED TANKS
Small amounts of air loss is normal
in any tank. To prevent failure and
properly maintain a pre-charged water
tank, check the pressure on a yearly
basis.
1. Disconnect power to pump.
2. Open a faucet nearest the tank and
allow all water to drain from the
tank.
3. Measure the tank pre-charge at the
valve stem using a tire gauge.
4. If necessary, adjust the pre-charge
with an air pump: Precharged
pressure for the this pump is 28-30
psi.
5. Prime the pump.
6. Reconnect power.
7. Close faucet.
