– 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. 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.
