18. 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 recov-
ery cylinders are employed. Ensure that the correct number of cylinders for holding the to-
tal system charge are available. AII 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 con-
cerning 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 recov-
ery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in
recovery units and especially not in cylinders.
lf compressors or compressor oils are to be removed, ensure that they have been evacu-
ated 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 com-
pressor 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.'
19. Transport of equipment containing flammable refrigerants (Annex CC.1)
Compliance with the transport regulations
20. Discarded appliances supplies flammable refrigerants
See National Regulations.
21. Storage of equipment/appliances
The storage of equipment should be in accordance with the manufacturer's instructions.
22. Storage of packed (unsold) equipment
Storage package protection should be constructed such that mechanical damage to the
equipment inside the package will not cause a leak of the refrigerant charge.
The maximum number of pieces of equipment permitted to be stored together will be de-
termined by local regulations.
23. Marking of equipment using signs
See local regulations
