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).
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.
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 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. If broken, replace the tank.
NOTE:
Once a bladder is leaking or broken, the bladder cannot
be repaired. The tank must be replaced.
LUBRICATION
The bearings used in the pumps are lifetime 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. Disconnect power to the pump, so water does not refill the
precharged tank.
2. Open a faucet nearest the tank and allow all water to drain
from the tank.
3. Measure the tank precharge at the valve stem using a tire
gauge.
4. If necessary, adjust the precharge with an air pump 28 - 30
psi on 1/2, 3/4 and 1 HP pumps.
5. Reconnect power to the pump.
