Operating Instructions and Parts Manual

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
out the power disconnect to prevent unexpected application of power.
Débrancher de la source d’alimentation puis
dissiper toute la pression du système avant d’essayer d’installer,
de réparer, de déplacer ou de procéder à l’entretien. Verrouiller
le sectionneur de courant en position ouverte (OFF). Étiqueter le
sectionneur de courant pour éviter toute mise sous tension imprévue.
Protect the pump from freezing during winter
conditions.
MISE EN GARDE
Protéger la pompe du gel pendant l'hiver.
DRAINING THE PUMP
Drain openings are provided on all models.
To drain the pump:
1. Remove drain fitting and prime plug to vent the system (see
Figure 7).
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 6).
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 to the tank and allow all water to drain
from the tank, then close.
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 HP and 3/4 HP pumps.
5. Reconnect power to the pump.

REMOVING OLD SHAFT SEAL
Disconnect power and release all
pressure from the system before attempting to install, service, relocate or
perform any maintenance.
1. Disconnect power to the pump.
2. Open a faucet nearest to the tank and allow all water to drain
form the tank, then close.
3. Remove the four cap screws holding the pump housing (volute)
to the motor (Figure 8).
4. Separate the pump housing (volute) from the motor to expose
the diffuser and the seal plate.
5. Remove the two cap screws and diffuser from the seal plate to
expose the impeller.
6. Remove the rear cover on the end of the motor opposite the
impeller.
7. Secure a 7/16" wrench across wrech flats of shaft to keep the
shaft from rotating and remove the impeller by hand (standard
right hand thread). Be sure to hold onto the seal plate when
removing the impeller from the shaft.
