31. 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.
32. 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
is 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 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.
