RECOVERY
When removing refrigerant from a system, either for servicing or decommissioning, it is re-
commended 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 sys-
tem 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 all appropriate refri-
gerants including, when applicable, 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 as-
sociated 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.
