  • Installation Tips:

    Face to the mouth of the hose connector and then bind it clockwise with the sealing tape for 3-5 circles. Then tightly screw up it with the connector of compressor and horn.


    1. Remove compressor, receiver drier or accumulator, orifice tube or expansion valve.

    2. Flush the condenser and evaporator using NON-OIL BASED A/C flush. On expansion valve systems THE VALVE MUST BE REMOVED before the evaporator can be flushed. FLUSHED CONDENSERS FROM OUTLET TO INLET AND EVAPORATORS FROM INLET TO OUTLET.

    Warning: Newer Style condenser designs are very hard, and sometime it would be impossible to do flush, In those cases it is suggested that if the compressor has a major failure the condenser should be replaced.

    3. Drain all the oil from the new compressor and dispose of according to local, state and federal laws. NOTE: if you compressor has a drain plug you will need to open it up and drain what oil is in there too.

    4. Install half oil charge into the compressor and the remainder throughout the system. Turn compressor shaft 8-10 full revolutions to insure front seal and other internal parts are lubricated.

    5. Install new receiver drier or accumulator and new orifice tube or expansion valve.

    6. Evacuate the A/C system for a minimum of one hour.

    7. After evacuation install half the refrigerant charge and let the system set for 1 minute. This will allow the refrigerant to pick up oil and spread more evenly throughout the system.

    8. Start engine whit A/C controls on MAX AIR with door and windows open.

    9. Add the remaining charge of refrigerant as called for by the manufacture.
