7b). The ground conductor must not
be smaller than the circuit conductors
supplying the motor.
Disconnect power
and release all pres-
sure 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 filled
with water.
1. Remove prime plug (Figure 4 or 5).
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 pres-
sure from the system before attempting
to install, service, relocate or perform any
maintenance. Lock the power disconnect
in the open position. Tag the power dis-
connect to prevent unexpected applica-
tion of power.
Protect the pump
from freezing dur-
ing 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.
2. Drain all piping to a point below
the freeze line.
DRAINING THE TANK
Conventional tanks can be drained by
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 pres-
sure is released. No draining is neces-
sary.
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 hous-
ing (volute) and the piping to the well.
There must be water in the pump hous-
ing (volute) at all times when the pump
is running to avoid internal damage of
seal members (Priming the Shallow
Well).
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 sys-
tem to release all pressurized water
in the system.
3. Prime the pump (Priming the
Shallow Well).
4. Reconnect the power to the pump.
NOTE: As the pump refills 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 water-
logged, the bladder is normally leaking
or broken.
1. Test the tank by depressing the air
valve. The air valve will expel water if
the bladder is broken.
2. Replace the tank.
NOTE: Once a bladder is leaking or bro-
ken, the bladder cannot be repaired. The
tank must be replaced.
LUBRICATION
The bearings used in the pumps are life-
time lubricated at the factory and require
no additional lubrication.
PRECHARGED TANK
Some air is lost through the bladder in
any tank. To prevent tank failure, check
the tank precharge on a yearly basis.
1. Open a faucet nearest the tank and
allow all water to drain from the
tank.
2. Measure the tank precharge at the
valve stem using a tire gauge.
3. If necessary, adjust the precharge
with an air pump 28 - 30 psi on 1/2,
3/4 and 1 HP pumps.
