OPERATION
PRIMING THE SHALLOW WELL PUMP
To prevent damage to the pump, do not start
motor until pump has been filled with water.
NOTE:
When the deep well pump is used with the bolt-on shallow well
jet, be sure the control valve slot (Figure 11) is in the vertical (open) position
at all times.
1. Remove prime plug.
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. Do not allow
pump to get hot.
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.
PRIMING THE DEEP WELL PUMP
To prevent damage to the pump, do not start
motor until pump has been filled with water.
1. Remove prime plug.
2. Fill pump and piping completely full of water.
3. Replace the prime plug.
4. Close the control valve (Figure 11) and open a nearby faucet.
5. Start the motor. The pressure inside the pump body will build almost
immediately as the pump, jet and piping become completely filled
with water.
6. Slowly open the control valve. Water will begin to flow. Continue to
open the control valve until maximum flow is achieved. Opening the
valve too far will cause the water to stop flowing.
7. Adjust the valve until there is a steady flow of water. The valve should
be opened as much as possible without losing pressure.
8. Let the system operate for several minutes to flush all piping.
9. Close the faucets and allow the pump to build pressure in the tank.
When the pressure reaches the cut-out setting, the motor will stop.

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.
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.
Pre-charged 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
(See Priming the Shallow Well or Priming the Deep Well Sections).
WATERLOGGED TANKS:
CONVENTIONAL
When a tank system has an inadequate ratio of air and water, the pump
will start and stop often and erratically.
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 (See Priming the Shallow Well or Priming the Deep
Well Sections).
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: PRE-CHARGED
If a pre-charged 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.
