to the task being carried out,
an oil and refrigerant sample
shall be taken in case analysis
is required prior to re-use of
reclaimed refrigerant. It is
essential that electrical power
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overll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lled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
ammablerefrigerant.When
removing refrigerant from a
system, either for servicing
or decommissioning, it is
recommended good practice
