g) Start the recovery machine and operate in accordance with
manufacturer's instructions.
h) Do not overfill cylinders. (No more than 80 % volume liquid
charge).
i) Do not exceed the maximum working pressure of the cylinder,
even temporarily.
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.
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.
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
