SAFETY GUIDELINES - DEFINITIONS Safety is a combination of common sense, staying alert and knowing how your compressor works. Read this manual to understand this compressor.
When installing or moving the compressor WARNING 6. A minimum clearance of 18 inches between the compressor and a wall is required because objects could obstruct airflow. This compressor is extremely top heavy. The compressor must be bolted to the floor with vibration pads before operating to prevent equipment damage, injury or death. Do Not tighten bolts completely as this may cause stress to the tank welds. Chart 1a. 7.
Follow the safety precautions for electrical connections 1. Follow all local electrical and safety codes, as well as the National Electric Code (NEC) and the Occupational Safety and Health Act (OSHA). 3. Protect wires from contact with sharp objects. CAUTION 2. Wiring and fuses should follow electrical codes, current capacity and be properly grounded. All electrical connections should be made by a qualified electrician. Plan ahead to protect your eyes, hands, face and ears Dress for safety 1.
Spraying precautions WARNING 1. Do Not spray in the vicinity of open flames or other places where a spark can cause ignition. Do Not smoke when spraying paint, insecticides, or other flammable substances. Never point a spray gun at yourself or any other person or animal. Accidental discharge may result in serious injury. Reduce the risk of dangerous environment Be informed about the materials you use 1.
TYPICAL COMPRESSOR INSTALLATION WIRING GLOSSARY OF TERMS Air Filter Pressure Switch Porous element contained within a metal or plastic housing attached to the compressor cylinder head which removes impurity from the intake air of the compressor. Device which automatically controls the on/off cycling of the compressor. It stops the compressor when the cut-off pressure in the tank is reached and starts the compressor when the air pressure drops below the cut-in pressure.
WIRING WIRING WARNING ALL ELECTRICAL WIRING SHOULD BE DONE BY A QUALIFIED ELECTRICIAN General Information DO NOT MAKE CONNECTIONS AT THE PRESSURE SWITCH (Units with Magnetic Starters) Single Phase Adequate wiring and motor protection Incoming power should should be provided for all stationary be connected to L1 and compressors. Wiring used for other L2 at the Top of the machinery should not be used. A Magnetic Starter.
STARTING THE COMPRESSOR STARTING THE COMPRESSOR Prior to actually running the compressor, check the following items: Crankcase oil - Make sure the sight glass shows ½ full or slightly above. Make sure all rags, tools, oil, etc. are away from the unit. Open the air system to free it of any pressure. Switch the compressor on for a few revolutions to make sure the rotation is correct. Correct rotation is clockwise when facing the sight glass on the pump.
(Gas Drive Models) PLEASE REFER TO YOUR ENGINE OPERATION MANUAL FOR PROPER STARTING INSTRUCTIONS. GASOLINE DRIVEN COMPRESSORS ARE EQUIPPED WITH A COLD START VALVE FOR LOADLESS STARTS. NOTE: IN SOME INSTANCES, IT STILL MAY BE NECESSARY LIFT THE TOGGLE ON THE UNLOADER/PILOT VALVE TO RELIEVE THE HEAD PRESSURE. See Page 11 Battery Connection Instructions for Electric Start Engines Note:Make sure to follow instructions carefully to avoid a short and possible damage to the starter solenoid and/or battery. 1.
TROUBLESHOOTING GUIDE Low discharge pressure 1. Compressor too small for application 2. Air leaks 3. Restricted intake air 4. Blown gasket(s) 5. Broken or misaligned valves 1. Reduce air demand or use a compressor with more air capacity. 2. Listen for air leaks. Apply a soap solution to all fittings and connections. Bubbles will form at points of leakage. Tighten or replace fittings or connections. 3. Clean or replace air filter. 4. Replace necessary gaskets. 5.
TROUBLESHOOTING GUIDE (Continued) Pressure switch unloader constantly leaking air 1. Malfunctioning check valve Pressure switch not unloading 1. Malfunctioning pressure switch 1. Replace check valve if unloader bleeds constantly. ! 1. Replace pressure switch if it does not release air pressure briefly when unit shuts off. ! Excessive vibration 1. Improper installation 2. Loose belts 3.
