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 identified
as GRD. The ground connection must
be made at this terminal (Figure 8).
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
pressure from the system before
attempting to install, service, relocate or
perform any maintenance. Lock the
power disconnect in the open 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.
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
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 (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
system 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
waterlogged, 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
broken, the bladder cannot be repaired.
The tank must be replaced.
