• If compressors or compressor oils are to be removed, ensure that they have been
evacuated to an acceptable level to make certain that ammable refrigerant does
not remain within the lubricant. The evacuation process shall be carried out prior to
returning the compressor to the suppliers. Only electric heating to the compressor
body shall be employed to accelerate this process. When oil is drained from a
system, it shall be carried out safely.
