I N S P E C T I O N ALL PUMPS: Regular inspection, cleaning filters, and “flushing” may prevent extensive repairs. Dirty or clogged filter elements can cause overheating (in excess of 200°F) and possible pump failure. It is normal for the pump surface and immediate output air temperatures to reach 200°F when the unit is run continuously under a heavy load or high pressure settings. o If there is evidence of overheating or excessive noise, stop immediately. o High-pressure operation will shorten pump’s life. o Keep external surfaces clean for proper heat dissipation. o Do not allow pump to operate in ambient air temperatures excess of 40°C (104°F). Failures due to pressure buildup are due to the following: o Improper setting of pressure relief valve o Leaks in airline connections o Damaged filter canister threads o Collapsed or kinked air lines, dirty filter elements o Vanes sticking in the rotor slots ELECTRICAL MOTORS: Some electrical motors are equipped with a thermal protector that shuts motor down automatically when subjected to mechanical or electrical overloads. Ensure electrical power source corresponds to what is on the motor name plate. AIR DRIVEN MOTORS: The air coming out of the discharge port will cool as it expands. It is important that the PVC extension (included with the blower) is used to extend the muffler from the motor discharge port. This will help prevent ice from forming on the muffler due to moisture in the air. M A I N T E N A N C E FILTERS: • Change inlet filter every 200 running hours or if the pressure gauge shows a drop in pressure. • Change discharge filter every 200 running hours or if the pressure gauge shows an increase in pressure. FLUSHING INSTRUCTIONS: 1. Perform this procedure in a well ventilated area. 2. Wear solvent resistant gloves and eye protection while performing the flushing procedure. 3. Disconnect airline hose and respirator to prevent contamination. 4. Remove inlet filter assembly and pressure relief valve, to prevent damage to pump from back pressure. 5. Add 10-15 squirts of flushing solvent, Allegro P/N: 9700-11, through the inlet port opening. 6. Turn pump on and let run for 1 minute to flush out contaminants. 7. Repeat flushing procedure if pump is in extremely dirty or is under performing. 8. Replace inlet filter assembly and pressure relief valve. 9. Replace exhaust filter and inlet filter. 10. Reconnect airline hose and respirator, do not use respirator until all steps are complete. 11. Turn pump on for 10 minutes, this allows the flushing solution to dry out completely. AIR DRIVEN MOTOR: (P/N 9850) 1. Disconnect inlet plumbing from pump and muffler assembly. 2. Add 10-15 squirts of solvent into the inlet port. 3. Rotate the shaft by hand in both directions for a few minutes. 4. Reassemble plumbing and reconnect the inlet air supply line and slowly apply pressure. 5. Flushing liquid should slowly exit the exhaust port, let run for 10 minutes 6. Reassemble exhaust assembly. WARNING! Keep face away from exhaust port. DO NOT flush unit with KEROSENE OR OTHER COMBUSTIBLE LIQUIDS. Personal injury and/or property damage will result. LUBRICATION: (For Air Driven Pump Only P/N: 9850) To lubricate the air motor (which drives air driven Model: A-400AD), use a detergent SAE #10 automotive engine oil. DO NOT lubricate air pump. For proper operation and maximum service-life, an automatic air line lubricator has been installed inline just before of the air motor. • The lubricator should be adjusted to feed one drop of oil per minute. • Lubrication is necessary for all internal moving parts and rust prevention. • Excessive moisture in the air line can cause rust formation in motor and might also cause ice to form in the muffler due to expansion of air through the motor. • The moisture problem can be corrected by installing an additional moisture separator inline. VANE REPLACEMENT: (Consult factory prior to replacing vanes.) To replace vanes or inspect the pump interior: 1. Remove only the endplate by removing the six bolts holding the end plate to the body. ...
