is available before the task is
commenced.
• Become familiar with the
equipment and its operation.
• Isolate system electrically.
• Before attempting the procedure
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.
• Pump down refrigerant system,
if possible.
• If a vacuum is not possible,
make a manifold so that
refrigerant can be removed
from various parts of the
system.
• Make sure that cylinder is
situated on the scales before
recovery takes place.
• Start the recovery machine and
operate in accordance with
manufacturer's instructions.
• Do not overfill cylinders.
(No more than 80% volume
liquid charge).

• Do not exceed the maximum
working pressure of the
cylinder, even temporarily.
• 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.
• Recovered refrigerant shall
not be charged into another
refrigeration system unless
it has been cleaned and
checked.
• Equipment shall be labelled
stating that it has been
decommissioned 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. 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.
