j) When the cylinders have been filled correctly and the process completed,
make sure that the cylinders and the equipment are removed from site promptly
and all isolation valves on the equipment are closed off.
k) Recovered refrigerant shall not be charged into another refrigeration system
unless it has been cleaned and checked.
17. Labelling:
Equipment shall be labelled stating that it has been de- commissioned and
emptied of refrigerant. The label shall be dated and signed. For appliances
containing FLAMMABLE REFRIGERANTS, 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 be 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
the flammable refrigerant. If in doubt, the manufacturer should be consulted. 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.
