manufacturer if in doubt. The recovered refrigerant shall be returned to the
refrigerant supplier in the correct recovery cylinder, and the relevant Waste
Transfer 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 flammable refrigerant does not remain within the lubri-
cant. 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.
