Convertible Jet Pumps Models DCJ500 (#6330) & DCJ750 (#6331) Operating & Installation Instructions

Please read these instructions carefully. Failure to comply with instructions and the designed operation of this system may void the warranty.
Your pump has been carefully packaged at the factory to prevent damage during shipping. However, occasional damage may occur due to rough handling. Carefully inspect your pump for damage that could cause failure. Report any damage to your carrier or your point of purchase.
This pump is designed for shallow well installation for water levels up to 25 feet, with an injector installed on the pump body; or for deep well installation for water level up to 80 feet, with 1-1/4” pipes and injector down in the well. A pressure switch and pressure gauge are standard features. The pump starts when the pressure drops to a cut-in setting (30 psi) and cut- out setting (50 psi). The DuroJet Convertible Jet Pump can be mounted to either a pre-charged horizontal pressure tank or used with a pre-charged free- standing pressure tank. The pumps can also be used with conventional air-to- water tanks. For deep well applications, replace the short tube in the ejector assembly to long tube #302922 (sold separately).
NOTE: Pre-assembled pump and pre-charged pressure tank packages are also available.

General Safety Information

1. Know the pump application, limitations and potential hazards.

   • Always install a pressure relief valve to match the system pressure rating and the maximum flow rate.
   • Disconnect power and relieve 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. Install a screen around the inlet pipe to prevent entrapment of swimmers (if applicable).

2. Drain all liquids from the system before servicing.

3. Secure the discharge line before starting the pump. An unsecured discharge line will whip and possibly cause personalinjury and/or property damage.

4. Check hoses for weak or worn conditions before each use. Make certain all connections are secure.

5. Periodically inspect pump and system components. Perform maintenance as required.

6. Personal Safety:

   • Wear safety glasses at all times when working with pumps.
   • Keep work area clean, uncluttered, and properly lighted – replace all unused tools and equipment.
   • Keep visitors at a safe distance from the work area.

7. When installing the pump, cover the well to prevent foreign matter from falling into the well and contaminating the water and damaging internal mechanical pumping components.

8. Always test the water from the well for purity before use. Check with the local health department for test procedures.

9. The complete pump and piping system MUST be protected against freezing temperatures. Freezing temperatures could cause severe damage and void the warranty.

10. Do not run the pump dry or damage will occur.

11. The unit should be connected to a grounded circuit equipped with a ground fault interrupter device.

12. Before installing the pump, have the electrical outlet checked by a licensed or certified electrician to make sure the outlet is properly grounded.

13. Make sure the line voltage and frequency of the electrical current supply agree with the motor wiring.

14. Do not attempt repairs to the electric motor. All repairs to the motor must be completed at a licensed or certified electrical motor repair shop.
    Do not touch an operating motor. Modern motors are designed to operate at high temperatures.

15. Avoid kinking the electrical cord and protect it from sharp objects, hot surfaces, oil, and chemicals. Replace or repair damaged or worn cords immediately.

16. Keep fingers and foreign objects away from ventilation and other openings. Do not insert any objects into the motor.
    Risk of electrical shock! Never connect the green (or green and yellow) wire to a line terminal!

17. Use wire of adequate size to minimize voltage drop at the motor.

    • Do not handle a pump or pump motor with wet hands, when standing on a damp surface or when standing in water. Fatal electrical shock could occur.
    • The pump motor is equipped with an automatic resetting thermal overload protector and may restart unexpectedly. The overload protector tripping is an indication of motor overloading because of operating pumps at low heads (low discharge restriction), excessively high or low voltage, inadequate wiring, and incorrect motor connections.

18. This pump has been evaluated for use with water only. Do not use to pump flammable or explosive fluids such as gasoline, fuel, oil, kerosene, etc. Do not use in an explosive atmosphere.

Pre-installation

Tanks – Conventional Storage (Air to Water Tank)
The function of the tank is to store a quantity of water under pressure. When full, the tank contains approximately 2/3 water and 1/3 compressed air. The compressed air forces the water out of the tank when a faucet is opened. An air volume control automatically replaces air lost or absorbed into the water. The usable water, or drawdown capacity, of the tank is approximately 1/6 of the tank’s total volume.
NOTE: If you have a conventional tank using an air volume control, the tube to the air volume control must be connected to the pump suction pipe.

Tanks – Pre-charged Storage
A pre-charged storage tank has a flexible bladder or diaphragm that acts as a barrier between the compressed air and the water. This barrier prevents the air from being absorbed into the water and allows the water to be acted on by compressed air at initially higher than atmospheric pressures (pre-charged). More usable water is provided than with a conventional type tank. Pre-charged tanks are specified in terms of a conventional tank. For example, a 20-gallon precharged tank will provide the same usable water or drawdown capacity as a 40-gallon conventional tank, but the tank is smaller in size.
Pressure Switch
The pressure switch provides for automatic operation. The pump starts when pressure drops to a cut-in setting. The pump stops when pressure reaches a cut-out setting. The factory set pressure switch setting is 30 psi (cut-in) and 50 psi (cut-out).
Wells
A new well should be pumped clear of sand before installing the pump. Sand will damage the pumping parts and seal. The drawdown level of the well should not exceed the maximum rated depth for the pump. The capacity of the pump will be reduced and a loss of prime may occur.
Location
Select a location as close to the water supply as possible. Be sure to comply with any provincial/state or local codes regarding the placement of the pump. The equipment must be protected from the elements. A basement, frost-proof pit or heated pump house are good locations. Make sure the pump has proper ventilation.
Piping
Piping may be copper, rigid PVC plastic or flexible polyethylene plastic.
The pipe must be clean and free of rust or scale. Use a pipe joint compound on the male threads of the metal pipe. Teflon tape should be used with plastic threads. All connections must be airtight to ensure normal operation.
Slope all inlet piping upwards towards the pump to prevent trapping air. Unions or hose couplings can be installed near the pump to facilitate removal for servicing or storage.
Pipe Sizes
Long horizontal pipe runs and an abundance of fittings and couplers decrease water pressure due to friction loss.
Friction losses in the suction pipe must be taken into consideration when the horizontal offset is greater than 50 feet. The suction pipes should be increased from 1” to 1-1/4” and from 1-1/4” to 1-1/2”. This will reduce friction losses and allow the pump to give maximum performance.
Never run the pump dry. Damage to the seal may occur. fill the pump body and suction pipe before turning on the power.

DuroJet Convertible Shallow Well Jet Pump Application
The DuroJet Convertible Shallow Well Jet Pumps have only one pipe between the pump and the water supply. This pump is designed for pumping potable water in applications where water is located less than 25 feet vertically from the pump.
Drilled Well

1. Install a foot valve on the first section of the pipe.

2. Lower the pipe into the well.

3. Add pipe until the foot valve is 5 feet below the lowest anticipated water level.
   CAUTION! The foot valve should be at least 18” from the bottom of the well or sand or sediment could be drawn into the system.

4. After the proper depth is reached, install a well seal or pitless adapter to support the pipe and prevent surface water and other contaminants from entering the well.

5. Slope the horizontal pipe upward toward the pump to eliminate trapping air. Sloping the pipe will also aid in priming the pump.

6. Fasten the pump down securely in its permanent location to minimize pump vibration when operating.

Driven Well (or Sandpoint Well)

1. Drive the point several feet below the water table.

NOTE: A packer-type foot valve can be installed in the well. This type of foot valve allows the well to be filled with water when priming and makes the inlet pipe much easier to test for leaks. Follow the manufacturer’s instructions when installing the packer-type foot valve. As an alternative, an in-line check valve can be used with a driven well. The pipe between the check valve and the water level will always be under vacuum. Leaking joints or couplings will allow air to leak into the pipe and cause abnormal pump operation. Make sure to use pipe joint compound on all male pipe threads.

Dug Out, Cistern, Lake and Spring Installation

1. Install a foot valve on the inlet pipe and lower it into the water.

CAUTION! The foot valve should be at least 18” from the bottom or sand or sediment could be drawn into the system.

NOTE: When a lake is used as a water supply, make sure the inlet pipe is deep enough to be submerged at all times. Slope the horizontal piping upward toward the pump to prevent trapping air. The pipe must be removed during winter months or protected against freezing.

• Protect the pipe from damage from swimmers and boats.
• Install a screen around the inlet pipe to prevent entrapment of swimmers.

DuroJet Convertible Shallow Well Jet Pump with Conventional Storage Tank

1. Install air volume control on the tank.
2. Connect the tube from the air volume control to the tee in the suction. Be sure the connections are tight. Leaking can cause the pump not to prime.
3. Install a valve and an isolator hose between the tank and the hose plumbing to aid in pump removal for servicing and forreducing the noise transmitted to the house through the piping.
4. Provide a hose bib (faucet) at the lowest point in the system to drain the system for service or storage.

DuroJet Convertible Shallow Well Jet Pump with Precharged Storage Tank

1. Shut off the power to the pump.
2. Open the 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 pressure gauge.
4. If necessary, precharge with an air pump to 2 PSI below the cut-in pressure of the pump.
5. Slope the horizontal pipes upward toward the pump to prevent trapping air. If the horizontal distance exceeds 25 ft.

Electrical

WARNING – Reduced risk of electric shock during operation of this pump requires the provision of acceptable grounding:

• When the means of connection to the supply-connection box is other than grounded metal conduit, ground the pump back to the service by connecting a copper conductor, at least the size of the circuit conductors supplying the pump, to the grounding screw provided within the wiring compartment.
• This pump is provided with a means for grounding. To reduce the risk of electric shock from contact with adjacent metal parts, bond the supply box to the pump-motor-grounding means and to all metal parts accessible at the wellhead.

1. THIS PUMP MUST BE INSTALLED BY QUALIFIED PERSONNEL. Check local electrical and building codes before installation.

2. The Jet Pump Motors are pre-configured at the factory for 230VAC, 60 Hz operation. If 115VAC operation is required, the Jet Pump Motor can be easily switched from 230VAC to 115VAC, 60 Hz. Refer to the Motor Label at the motor. If the motor is converted from 230 VAC to 115 VAC, an electrician should ensure the electrical branch circuit can handle the higher currents. The Voltage Selector should be reviewed to ensure the voltage selected at the motor matches the voltage supplied.
   Check the pump label for the proper voltage required. Do not connect to a voltage other than that shown on the label. Cross-check the power supply voltage with a voltmeter and the motor selector knob.

3. A separate branch circuit is required. The pump should be connected to a separate electrical circuit directly for the main electrical service panel. Do not use an extension cord.

4. A permanent ground connection must be made from the pump motor to the grounding bar at the service panel. Do not connect the pump motor to a power supply until the pump is permanently grounded.
   The ground wire should be copper and at least as large as the power supply wire size. The power supply wire should be copper.

5. Recheck the voltage after the pump motor has started. There should be some voltage drop, but the voltage drop should be no more than 5% of the nominal voltage.
   CAUTION: Failure to ground this unit properly may result in severe electrical shock.

The motor has been factory-connected for 230V. Refer to the motor nameplate and instruction sheet for reconfiguration to 115V. Use copper conductors only for field wiring connections.
CAUTION: This pump has been evaluated for use with water only.
WARNING: To reduce the risk of electric shock, see the instruction manual for a proper installation procedure. Risk of

Operation

Priming the DuroJet Convertible Shallow Well Jet Pumps
To prevent damage to the pump, do not start the motor until the pump has been filled with water.

1. Remove the prime plug.
2. Fill the pump and piping full of cold water.
3. Replace the prime plug.
4. Open a faucet to vent the system.
5. Start the motor. Water will be pumped within a few minutes. If the pump fails to prime within 5 minutes, stop the motor and refill the pump with cold water. The priming time is proportional to the amount of air in the inlet pipe. Refill as often as necessary.
6. Let the system operate for several minutes to flush all pipes.
7. Close the faucet and allow the pump to build pressure in the tank. When the pressure reaches the cut-out setting, themotor will stop.

The system is now in operation and will automatically cycle on demand.

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.
CAUTION! Protect the pump from freezing during winter conditions.
Draining the DuroJet Convertible Shallow Well Jet Pump
Drain openings are provided on all models. To drain the pump:

1. Remove the drain fitting and the prime plug to vent the system.
2. Drain all piping to a point below the freeze line.

Priming and Setting the DuroJet Convertible Deep Well Jet Pumps
When using DuroJet pumps on deep well applications, a longer tube for ejector assembly is required. WaterGroup’s part number for the long tube is (#302922).

1. Remove the prime plug from the pump discharge.
2. Fill the pump and piping full of cold water.
3. Replace the prime plug
4. Make sure that the long tube is replaced with a short tube in the ejector assembly.
5. Start the pump. When the pump is properly primed, a high pressure will show immediately on the gauge.
6. If no pressure is shown, stop the pump and repeat Steps 1 – 3. Several attempts may be required before the pump isprimed.
7. The pressure obtained in Step 6 will be the minimum operating pressure of the pump.
8. When the correct pressure is set, close the faucets. Pressure will rise to close the pressure switch and the pump will stop automatically.
9. With the pump primed and set, check operation by opening and closing faucets as necessary, allowing the pump to cycle automatically.

NOTE: Systems with long offset lines or driven well points may take several attempts to prime. If your pump does not prime within one or two minutes, repeat Steps 1 to 3. When the pump is primed and running, check operation by opening and closing faucets as necessary, allowing the pump to cycle automatically.
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.
CAUTION! Protect pump from freezing during winter conditions.

Draining the DuroJet Convertible Deep Well Jet Pumps
Drain openings are provided on all models. To drain the pump:

1. Remove the drain fitting and the 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 a plug or the air volume control to vent the tank.
Precharged tanks force virtually all the water from the tank when the 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 page seven for priming information).
Precharged Tank
Some air is lost through the bladder in any tank. To prevent tank failure, check the tank precharge every year.

1. Open a faucet nearest the tank and allow all water to drain from the tank.
2. Measure the tank precharge at the valve stem using a tire gauge.
3. If necessary, adjust the precharge with an air pump to 2 PSI below the cut-in pressure of the pump.

Lubrication
The bearings used in the pumps are lifetime lubricated at the factory and require no additional lubrication.
Diagnosing 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.
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.

Diagnosing 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.

If a pump or part should prove defective within 24 months, return it to your dealer, and transportation charges prepaid. The repair will be made or a replacement pump or part will be supplied free of charge. The serial number of the pump must be supplied.
This warranty does not obligate the manufacturer to bear the cost of field labor or transportation in connection with the replacement or repair of defective parts or units, nor shall it apply to any product upon which repairs or alterations have been made unless authorized by the manufacturer.
The manufacturer shall in no event be liable for consequential damages or contingent liabilities arising out of the failure of any product, its power unit, or its accessories to operate properly. No express, implied or statutory warranty other than herein set forth is made authorized to be made by the manufacturer.
