Page 9: Compressor Lubrication And Cooling System
General Information 2.3 COMPRESSOR LUBRICATION AND COOLING SYSTEM The lubrication and cooling system consists of a reservoir, centrifugal fan, fan motor, aluminum finned fluid-cooler and after-cooler, thermal valve & fluid filter. High pressure forces the lubricant through a series of direction changes in the reservoir where it is separated from the air. -
Page 10: Compressor Discharge System
315-400 1425 2.4 COMPRESSOR DISCHARGE SYSTEM Air/fluid mixture has been forced into reservoir after compression. The reservoir has two basic functions: It acts as a primary fluid separator. It serves as the compressor fluid sump. The compressed air/fluid mixture enters the reservoir and is directed against the internal baffle. -

Page 18: Fluid Information
Fluid Information 3.1 FLUID GUIDE KHE compressors are filled & tested with Kerry lubricant. Refer Figure 3-1 for filler port, sightglass, quarter-turn valve location on the reservoir. The compressor is filled with the manufacturer’s recommended quantity of Kerry fluid. Inspection of the reservoir fluid level during installation or operation is recommended. -
Page 19: Ventilation And Cooling
clearance around the compressor is recommended for daily inspection and easy access to all compressor components. The area must have sufficient lighting for technicians to safely operate the compressor as well as perform maintenance work. The location should be free from standing water. The compressor’s base must be securely bolted to the floor with lag bolts. -
Page 20: Piping Connection
Maintain clean & fresh air, dust free, metal particle free and chemical vapor free in the compressor’s room. Housing the compressor within a poorly ventilated enclosure will cause higher operating temperature. Under no circumstances should a compressor be installed in an area exposed to toxic, volatile or corrosive atmosphere, nor should toxic, volatile or corrosive agents be stored near the compressor. -
Page 21: Fluid Level Inspection
Release system pressure by opening manual pressure relief valve prior to servicing. Failure to relieve system pressure could result in death or serious injury and property damage. The compressor after-cooler comes with an automatic condensate drain. The drain line should be installed to remove the condensate during compressor operation. -
Page 22: Motor Rotation Inspection
Installation Kaishan Compressor would like to emphasize the importance of providing adequate grounding for air compressors. The common practice of grounding units to a building’s structural steel may not provide adequate grounding protection, as paint and corrosion build-up may exist. -
Page 23: Fan Rotation Inspection
Installation 4.7 FAN ROTATION INSPECTION Fan motor rotation should be inspected. KHE compressors uses an axial fan for cooling. Fan rotation is inspected through an arrow shaped observation hole above the fan motor. The fan must rotate in the direction indicated by the arrow. Always inspect fan rotation through the observation hole. -
Page 24: Control Panel Layout
Provisions should be made to have the instruction manual readily available to the operator and maintenance personnel. If, for any reason, any parts of the manual become illegible or if the manual is lost, have it replaced immediately. The instruction manual should be read periodically to refresh one’s memory. This may prevent a serious accident. - Page 25 Households Register...
