SAVE THESE INSTRUCTIONS!
Labeling
Equipment shall be labeled stating that it has been decommissioned and emptied of refrigerant. The label
shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains
fl ammable refrigerant.
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 recovers cylinders are
employed. Ensure that the correct number of cylinders for holding the total system charge are available.
All cylinders to be used are designed for the recovered refrigerant and labeled 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 fl ammable 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 is it
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 leak. 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 shall be 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 fl ammable 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 form a system, it shall be carried out safely.
