INFORMATION SERVICING
18. Labelling
Equipment shall be labelled stating that it has been de-commissioned 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.
19. Recovery
•
When removing refrigerant from a system, either for service or decommissioning, all refrigerant should be collected and
handled in accordance with applicable laws and regulations.
•
When tranferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed.
Ensure that the correct numbers of cylinders for holding the total system charge are 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 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 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 retruning 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.
20. Transportation, marking and storage for units
1. Transport of equipment containing flammable refrigerants Compliance with the transport regulations
2. Marking of equipment using signs Compliance with local regulations
3. Disposal of equipment using flammable refrigerants Compliance with national regulations
4. Storage of equipment/appliances The storage of equipment should be in accordance with the manufacturer’s instructions.
5. 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 determined by local regulations
