Compressor Failure or System Contaminated

If either situation exists, discharge system using approved refrigerant recovery/recycling equipment and remove compressor, receiver-drier and expansion valve. Clean expansion valve screen. Flush entire system. Install new compressor and receiver-drier. New compressors contain correct amount of oil. If installing overhauled compressor, add 1.5 ounces of new refrigerant oil through suction port.
