   3. Keep visitors at a safe distance from work area.
   4. Make the workshop childproof use padlocks, master switches and remove starter keys.
5. Do NOT pump chemicals or corrosive liquids. Pumping these liquids shortens the life of the seals and moving parts and WILL void the warranty. Pump only clear water.
6. When installing pump, cover the well to prevent foreign matter from falling into well and contaminating the water and damaging internal mechanical pumping components.
7. Always test the water from the well for purity before use. Check with local health department for test procedure.
8. Complete pump and piping system MUST be protected against below freezing temperature. Freezing temperatures could cause severe damage and void the warranty.
9. Do not run the pump dry or damage will occur and will void warranty.
   1. Warning Risk of electrical shock! This pump is designed for indoor installation only. Risk of Electrical Shock! All wiring SHOULD be performed by a licensed or certified electrician.
10. Pressure switch is factory set at 30 ON/ 50 OFF and is NOT to be changed (will void warranty).
11. Before installing the pump, have the electrical circuit checked by a licensed or certified electrician to make sure the circuit is properly grounded.
12. Make sure the line voltage and frequency of electrical current supply agrees with the motor wiring.
13. Do NOT attempt repairs to the electric motor. All repairs to the motor must be completed by a licensed electrician.Warning Do NOT touch an operating motor. Modern motors are designed to operate at high temperatures.
14. Avoid kinking electrical wire and protect from sharp objects, hot surfaces, oil and chemicals.
15. 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!
16. To reduce the risk of electrical shock. The motor must be securely and adequately grounded for protection against shock.
17. Use wire of adequate size to minimize voltage drop at the motor.

WarningDo NOT handle pump or pump motor with wet hands, when standing on a wet or damp surface or when standing in water. Fatal electrical shock COULD occur.CautionPump motor is equipped with an automatic resetting thermal protector and MAY restart unexpectedly. Protector tripping is an indication of motor overheating because of operating pump at low heads (low discharge restriction), excessively high or low voltage, inadequate wiring, incorrect motor connections, excessive surrounding air temperature, inadequate ventilation, and/or defective motor or pump.

• WATER STORAGETanks are required for these pumps to operate as designed.
• TANKS - CONVENTIONAL STORAGEThe 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. Then 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 tanks total volume when operated on a 30/50 pressure setting (Figure 1).
• TANKS - PRECHARGED STORAGEA precharged 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 (precharged). More usable water is provided than with a conventional type tank. Precharged tanks are specified in terms of a conventional tank. For example, a 20 gallon precharged tank will have the same usable water or drawdown capacity as a 40 gallon conventional tank, but the tank is smaller in size (Figure 1).

PRIMING THE SHALLOW WELL PUMPWarningTo prevent damage to the pump, do NOT start motor until pump has been filled with water.

1. Remove prime plug (Figure 3).
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.
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.

Warning

• 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.
• Caution Protect the pump from freezing during winter conditions.

DRAINING THE PUMPDrain 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 TANKConventional 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 PUMPIf 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: CONVENTIONALWhen 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: PRECHARGEDIf 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.

LUBRICATIONThe bearings used in the pumps are lifetime lubricated at the factory and require no additional lubrication.PRECHARGED TANKSome 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.

KITS SECTIONREMOVING 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 wrench 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.
8. Remove the seal plate.
9. Pry the rotating shaft seal member (including stainless collar and rubber seal) from the impeller (Figure 9).
10. Push or pry the ceramic seat, and rubber seat ring free from the seal plate (Figure 9).
11. Remove loose particles from impeller hub and seal plate.

INSTALLING NEW SHAFT SEALWarningBefore handling shaft seal parts wipe hands clean. Dirt or grease MAY damage the seal.

1. Push seat enclosed in rubber into seal cavity on seal plate. Use a cardboard washer to protect polished surface when pushing against ceramic seat with any object. Be sure to remove cardboard washer.NOTE: Be careful not to scratch the ceramic surface of the seal seat.
2. Carefully slip seal plate over shaft. Do not disturb seal position in seal plate. The seal plate must be orientated during assembly so the two screw holes are on a horizontal line across the motor shaft (Figure 10). This placement should be done to ensure proper draining and priming.
3. Place rotating shaft seal member in position on impeller and press into place. Take care not to press against polished seal surface.
4. Position impeller on shaft and tighten securely (Figure 11).
5. Secure diffuser to seal plate using the two cap screws. Be sure the arrow on the front of the diffuser is pointing up and the screws are orientated on a horizontal line as described in Step 2.
6. Carefully position pump housing (volute) gasket over the diffuser onto the seal plate. In all shallow well applications care must be taken that the o-ring is clean and properly positioned on the venturi. Cleaning and positioning makes a good seal inside the diffuser when assembled.
7. Assemble the pump housing (volute) to the motor using the four cap screws. Be sure the pump housing (volute) gasket is positioned correctly and tighten the screws securely.

NOTE: Shaft must rotate freely and rear cover should be secured before operation.
