and checked.
17.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
flammable refrigerant.
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 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 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 value
and associated shut-off values 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 work 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.
19.Transport of equipment containing flammable refrigerants
Determined by local regulations.
20.Discarded appliances supplies flammable refrigerants
See National Regulations.
21.Storage package
（
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 determined by local
regulations.
