Electrical (Continued)

Check selector to voltage supply. They must match change if needed.

The voltage of power supply must match the voltage of the pump. The unit has dual voltage motors preset at the factory to 115 volts. The motors can be converted to 230 volts by turning the voltage selector to the desired voltage (see Figure 11). Use needle nose pliers to pull the selector out approximately 1/4 in., rotate and then reinsert in correct position.

Disconnect power and release all

pressure 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.

NOTE: When the deep well pump is used with the bolt-on shallow well jet, be sure the control valve slot (Figure 12) is in the vertical (open) position at all times.

Figure 12 - Control Valve

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 12) 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.

The system is now in operation and will automatically cycle upon 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.

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.
