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
EN
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-o 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.
