turer 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 refrig-
erants 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.
Equipment shall be labelled stating that it has been de-commissioned and emptied
of refrigerant. The label shall be dated and signed. For appliances containing flam-

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 are available. All cylinders to be used are designat-
ed for the recovered refrigerant and labelled for that refrigerant (i.e. special cylin-
ders for the recovery of refrigerant). Cylinders shall be complete with pressure-re-
lief 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. In ad-
dition, a set of calibrated weighing scales shall be available and in good working
