18. Recovery

• When removing refrigerant from a system, either for servicing or decommissioning, it is

recommended good practice that all refrigerants are removed safely.

• When transferring refrigerant into cylinders, ensure that only appropriate refrigerant

recovery cylinders are employed.

• Ensure that the correct number of cylinders for holding the total system charge is

available. All cylinders to be used are designated for the recovered refrigerant and

labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant).

• Cylinders shall be complete with a pressure-relief valve and associated shut-off valves

in good working order.

• Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.

• The recovery equipment shall be in good working order with a set of instructions

concerning the equipment that is at hand and shall be suitable for the recovery of all

appropriate refrigerants including, when applicable, flammable refrigerants.

• A set of calibrated weighing scales shall be available and in good working order. Hoses

shall be complete with leak-free disconnect couplings and in good condition.

• Before using the recovery machine, check that it is in satisfactory working order, has

been properly maintained, and that any associated electrical components are sealed to

prevent ignition in the event of a refrigerant release. Consult the 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 lubricant. The evacuation process shall be carried out before

returning the compressor to the suppliers. Only electric heating to the compressor body

shall be employed to accelerate this process. When the oil is drained from a system, it

shall be carried out safely.
