   • Keep work area clean, uncluttered and properly lighted replace all unused tools and equipment.
     Keep visitors at a safe distance from work area.

3. Do not pump chemicals or corrosive liquids. Pumping these liquids shortens the life of the pump’s seals and moving parts and will void the warranty. Pump ONLY clear water.

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

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

6. Complete pump and piping system MUST be protected against below-freezing temperatures. Freezing temperatures could cause severe damage and void the warranty.

7. Do not run the pump dry or damage will occur and will void warranty.

WARNING
This pump is designed for indoor installation only unless housed and protected from the elements. Failure to install indoors will significantly increase the risk of injury  or death from electrical shock and void warranty.

• Make sure the line voltage and frequency of the electrical current supply agree with the motor wiring.
• 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.
• Avoid kinking electrical cord and protect the electrical cords from sharp objects, hot surfaces, oil and chemicals.
• Keep fingers and foreign objects away from ventilation and other openings. Do not insert any objects into the motor.

WARNING
Risk of electric shock! Never connect the green (or green/yellow) wire to a live terminal!

• Use wire of adequate size to minimize voltage drop at the motor.
• Do not handle the pump or pump motor with wet hands, when standing on a wet or damp surface or when standing in water. Fatal electrical shock will occur.

WARNING

PRE-INSTALLATION

WATER STORAGE
Tanks are required for these pumps to operate as designed.

ANKS – CONVENTIONAL STORAGE
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 draw-down capacity, of the tank is approximately 1/6 of the tanks total volume when operated on a 30/50 pressure setting (Figure 1).

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 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 pre-charged tank will have the same usable water or draw-down capacity as a 40 gallon conventional tank, but the tank is smaller in size (Figure 1). Pre- charged to be set at 28 PSI with the tank empty of water.

LOCATION
Select a location as close to the water supply as possible. Be sure to comply with any state or local codes regarding the placement of the pump. The equipment must be protected from the elements or voids warranty. A basement or heated pump house is a good location. Make sure the pump has proper ventilation. The temperature surrounding the pump is not to exceed 100° F (38°C) or nuisance tripping of the motor overload may occur.
This pump is designed for indoor installation only, unless housed and protected from the elements. Failure to install indoors will significantly increase the risk of injury or death from electrical shock.

WELLS
A new well should be pumped clear of sand before installing the pump. Sand will damage the pumping parts and seal. The draw-down 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.

PIPING
Inlet piping may be copper, steel, or rigid PVC plastic.

• Flexible pipe is prohibited on suction pipe (inlet

• The pipe must be clean and free of rust or scale. Use a pipe joint compound on the male threads of the metal pipe. The plumber’s seal tape should be used with plastic threads. All connections must be airtight to insure normal operation.

• Slope all inlet piping upwards towards the pump to prevent trapping air. Unions or hose couplings can be installed near pump to facilitate removal for servicing or storage. A rubber hose installed between the water system and the house piping will reduce the noise transmitted to the house.

• The galvanized steel pipe and the couplings restrict the flow of return water back to the jet unless the couplings are machined.

• 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 pressure switch is preset and is NOT adjustable.

• PIPE SIZES
  Long horizontal pipe runs and an abundance of fittings and couplers decrease water pressure due to friction loss. See Chart 1, on page 7, to determine the proper pipe size.

• SHALLOW WELL INSTALLATION
  A shallow well jet assembly can be used with the deep well pump when the pump is located a maximum of 25 ft vertically above the water level  (see converting to shallow well pump on page 8). Shallow well installations have only one pipe between the pump and water supply (Figure 2).

DRILLED WELL (FIGURE 16, PAGE 16)

1. Install a foot valve on the first section of the pipe (Figure 2, Illustration A).

2. Lower the pipe into the well.

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

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

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

• Drive the point several feet below the water table.
• NOTE: A packer-type foot valve can be installed in the well (Figure 2, Illustration B). This type of foot valve allows the piping 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 (Figure 2, Illustration C). The pipe between the check valve and the water level will always be under a 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 WELL, CISTERN, LAKE AND SPRING INSTALLATION  (FIGURE 16, PAGE 16)

• Install a foot valve on inlet pipe and lower into water.
• The foot valve must be at least 18 in. from the bottom of the well 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 the entrapment of swimmers, wildlife and debris.

DEEP WELL INSTALLATION
DRILLED WELL (4 IN. OR LARGER) WITH TWO PIPE JET (FIGURE 16, ON PAGE 16 AND FIGURE 3, BELOW)

1. Assemble a 1-1/4 in. foot valve (not included) to the jet body. A 1-1/4 in. coupling is required to connect the larger pipe to the jet assembly.
2. Connect the 1 in. pipe threads into the smaller opening in the jet body.
3. Lower the jet into the well. Add pipe as needed. Be sure to use pipe joint compound, or plumber’s seal tape on all male threads.
4. Position the jet 10 – 20 feet below the lowest anticipated water level, but never closer than 5 feet from the bottom of the well, if possible.
5. Install a well seal to support the pipe and prevent surface water and other contaminants from entering the well.
6. Install the horizontal pipe from the well to the pump. Piping from the vertical well pipe to the pump should never be smaller than the well pipes.
7. Slope both pipes upward toward the pump to prevent trapping air. If the horizontal distance exceeds 25 feet, see Chart 1, on page 7 for the recommended pipe sizes.

DUG WELL, CISTERN, LAKE, AND SPRING WITH TWO PIPE JETS (FIGURE 16, PAGE 16)

1. Install a 1-1/4 in. foot valve (not included) to the jet body. A 1-1/4 in. coupling is required to connect the larger pipe to the jet assembly.
2. Connect the 1 in. pipe threads into the smaller opening in the jet body.
3. Lower the jet into the water below the lowest anticipated water level, but never closer than 5 ft. from the bottom. Sand or debris may be drawn into the system if the jet is too close to the bottom.
4. Provide protection for the jet and pipes against damage from boats or swimmers if a lake is used for the water supply. Install a screen around the inlet pipe to prevent the entrapment of swimmers, wildlife and debris.
5.  Slope the horizontal pipes upward toward the pump to prevent

1. Check tank pre-charge using a tire pressure gauge. Set air pressure in tank to 28 psi which is 2 psi below the pressure switch cut-in level. An air valve is located on the side and will accept a standard fitting from a bicycle pump or air line.
2. Check the pressure with the power off, faucets open and no water flowing (zero water pressure).
3. Install a valve and isolator hose between the system and the house plumbing to aid in pump removal for servicing and for reducing the noise transmitted to the house through the piping.
4. Provide a faucet at the lowest point in the system to drain for service or storage.

ELECTRICAL

• Risk of electrical shock. This pump is designed for indoor installation only, unless housed and protected from the elements.
• This installation must be in accordance with the National Electric Code and all applicable local codes and ordinances.
• Do not connect to electric power supply until unit is permanently grounded. Connect ground wire to the approved ground then connect the terminal provided.
• A metal underground water pipe or well casing at least 10 feet long makes the best ground electrode. If plastic pipe or insulated fittings
• are used, run a wire directly to the metal well casing or use a ground electrode furnished by the power company.
• There is only one proper ground terminal on the unit. The terminal is located under the pressure switch cover, is painted green and is identified as GRD. The ground connection must be made at this terminal (Figure 9).
• The ground conductor must not be smaller than the circuit conductors supplying the motor.
• The voltage of power supply must match the voltage of the pump. The pump has a dual voltage motor preset at the factory to LOW V (115 Volts). The motor can be converted to HIGH V (230 Volts) by changing the voltage selector to the desired voltage (See Figure 10). Use needle nose pliers to pull selector out, rotate and
• then reinsert in correct position. Voltage selected will be visible.
• Disconnect power and release all pressure from the system before attempting to install, service, relocate or perform any maintenance.

The terminal cover must be in place for safe operation. Ground in accordance with local and national electrical codes. Keep fingers and objects away from openings and rotating parts. Disconnect power sources before touching internal parts. See Figure 5 for appropriate wiring locations.

OPERATION

To prevent damage to the pump, do not start motor until pump has been filled with water.
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.

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.

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

MAINTENANCE

• WARNING
  Discwmæt power and release all pressure from the system before attempting to install, service, relæate or perform any maintenance. Lock tip power dsconnæt in the Wen (CFF) psitjW1.

• CAUTION
  Protect the pump from freezing during Mnter cw1ditjW1s.

• DRAINING THE PUMP
  Drain openings are provided on all mcdels.

To drain the pump:

1. Remove the drain fitting and plane plug to vent the system.
2. Draln all plplng to a pont below the freeze line.

DRAINING THE TANK
Conventional tanks can be drilled by openlng at the lowest point In the system. Remove plug cr 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  sorne time, be sure there Is water In the pump house Wolute) and the piping to the well. There must be water In the pump houslng  Wolute) at all times when the pump Is tunnlng 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 10).
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 the pump.
5. Reconnect power to the pump.
