and emptied of refrigerant. The label shall be dated and signed.
Ensure that there are labels on the equipment stating the equipment
contains 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 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 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-o 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 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 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.
