13.5 If compressors or compressor oils are to be removed, ensure that they
have been evacuated to an acceptable level to make certain that flammable
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.
