ensure that: Mechanical handling equipment is available, if
required, for handling refrigerant cylinders; All personal
protective equipment is available and being used correctly; The
recovery process is supervised at all times by a competent
person; Recovery equipment and cylinders conform to the
appropriate standards. d) Pump down refrigerant system, if
possible. e) If a vacuum is not possible, make a manifold so that
refrigerant can be removed from various parts of the system. f)
Make sure that cylinder is situated on the scales before recovery
takes place. 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.
15.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.
16.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
