the equipment are removed from site promptly and all isolation valves on the equipment are 

closed off. 

k) Recovered refrigerant shall not be charged into another refrigeration system unless it has 

been cleaned and checked.

15.Labelling

Equipment shall be labelled stating that it has been de-commissioned and emptied of 

refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment 

stating the equipment contains flammable refrigerant.

16.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 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 flammable refrigerants. 

In addition, 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 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 

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.
