automatic overload protection that will
prevent damage to the motor due to
overheating.
Do NOT connect to
electric power supply 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 fi ttings 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 terminal
on the unit. The terminal(s) is located
under the pressure switch cover, is painted
green and is identifi ed as GRD. The
ground connection must be made at this
terminal (Figure 7). The ground conductor
must not be smaller than the circuit
conductors supplying the motor.
Disconnect power
and release all pressure
from the system before attempting to install,
service, relocate or perform any maintenance.
Operation
PRIMING THE SHALLOW WELL
PUMP
To prevent damage
to the pump, do NOT start
motor until pump has been fi lled with water.
1. Remove prime plug (Figure 3 on page
3).
2. Fill pump and piping completely full of
water.
3. Replace the prime plug.
4. Open a faucet to vent the system.
5. Start the motor. Water will pump in a
few minutes. If pump fails to prime in
5 minutes, stop motor and refill pump
with water. Priming time is proportional
to the amount of air in inlet pipe.
6. Let the system operate for several

minutes to flush all pipes.
7. Close faucet and allow pump to build
pressure in tank. When the pressure
reaches the cut-out setting, the motor
will stop.
The system is now in operation and will
automatically cycle on demand.
Maintenance
Disconnect power
and release all pressure
from the 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.
Protect the pump
from freezing during
winter conditions.
DRAINING THE PUMP
Drain openings are provided on all models.
To drain the pump:
1. Remove drain plug and prime plug to
vent the system (see Figure 5 on page
3).
2. Drain all piping to a point below the
freeze line.

DRAINING THE TANK
Conventional tanks can be drained by
LINE
opening an outlet at the lowest point in the
system. Remove plug or the air volume
control to vent the tank.
Precharged tanks force virtually all the
water from the tank when system pressure
is released. No draining is necessary.
RESTARTING PUMP
If the pump has been serviced, drained or
has not been used for some time, be sure
there is water in the pump housing (volute)
and the piping to the well. There must be
water in the pump housing (volute) at all
times when the pump is running to avoid
internal damage of seal members.
WATERLOGGED TANKS:
CONVENTIONAL
When a tank system has an inadequate
ratio of air and water, the pump will start
and stop often and eradically.
1. Disconnect the power to the pump.
2. Open the lowest faucet in the system
to release all pressurized water in the
system.
3. Prime the pump (Priming the Shallow
Well Pump on page 4).
4. Reconnect the power to the pump.
NOTE: As the pump refi lls the tank with
water, the air volume control supplies the
tank with the correct air to water ratio for
the system to operate. If the air volume
control is good, the pump will shut off at
the desired cut-off and will be adjusted
correctly.
WATERLOGGED TANKS:
PRECHARGED
If a precharged tank becomes waterlogged,
the bladder is normally leaking or broken.
1. Test the tank by depressing the air
