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.
