Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders. 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.
