INNERSOLE-RAND. Owner’s Manual AIR COMPRESSORS Installation, Operation and Maintenance Instructions for Standard Two-Stage Lubricated Air Compressors {Electric Motor and Gasoline Engine Models Up to 30 Horsepower) IMPORTANT INFORMATION! READ AND FOLLOW THESE INSTRUCTIONS. RETAIN FOR REFERENCE. SAFETY operate or perform any maintenance, i you are uncertain about any of the instructions or procedures provided in this manual, contact DEFINITIONS Innersole-Rand.
receiver tank or system. If cooling of the discharge air is required, an air-cooled aftercare should be installed between the compressor discharge and the receiver tank or system. For maintaining the receiver tank or system air pressure within predetermined limits, the compressor may be operated with automatic start 8 stop control or constant speed control regulation.

Bot the unit to a firm, level foundation. Do not bolt uneven feat tightly to the foundation, as this will cause excessive stress on the receiver tank. Use metal shims. under the “short” feet if necessary.
excessive voltage drop during start-up. Refer to the National Electric Code (NEC) for information on selecting the proper wire size and securing electrical connections. If you connect additional electrical equipment to the same circuit, consider the {ital electrical goal wham selecting the proper wire size. DO NOT USE UNDERSIZED WIRE. MAGNETIC STARTER.

Typical Unicameral (A = Unload, B = Load) NOTE Turn the gasoline supply off when the compressor is not being used. NOTE Some gasoline engine driven compressors require 5.8 break-in hours of operation before reaching full capacity and speed, COMPRESSOR CONTROLS AUTOMATIC START & STOP CONTROL. This type of control applies to electric motor driven models under 10 horsepower. NOTE Automatic Start & Stop Control Is intended for use ‘when the motor will start no more than 6 times per hour.
The minimum possible differential is approximately 20% of cutout pressure. It is advisable to have as wide 2 differential as possible to avoid frequent starting and stopping of the unit. Note the pressure gauge reading af which the unit cuts-out and re-establish this point if necessary. Nita the interaction between the range and differential adjustments, i.e, if the cut-out is increased, the differential will lase increase, or if the differential is narrowed, the cut-out will be reduced, eic.
. Remove the pilot valve body and add enough shims to fill the gap measured in step five. 7. Screw the pilot valve body back into the frame end cover until the body is tight on the shims. 8.
BELT ADJUSTMENT CHECKING BELT TENSION. Check belt tension should be occasionally, especially if looseness is suspected. New belts must also be properly pensioned upon installation. PENSIONING BELTS. Bert pensioning can be achieved by Loosening the motor or engine anchor screws, pushing the motor or engine away from the pump, and re tightening the motor or engine anchor screws. Tomes units are equipped with a belt pensioning bolt that, when turned, pulls the motor or engine away from the pump.
TROUBLESHOOTING CHECK POSSIBLE CAUSE POINT BOEN® Clogged or dirty inlet and/or discharge line filter. Loose belt wheel or motor purlieu, excessive end play in motor shaft or loose drive belts. inadequate ventilation around belt wheel. Lubricant viscosity too low. Air leaks in air discharge piping Lubricant viscosity too high. Lubricant revel too high. Lubricant level foo iow. Detergent type lubricant being used. Extremely light duty cycles. Compressor located in damp or humid location.
