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.
a) Become familiar with the equipment
and its operation.
b) Isolate system electrically
c) 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.
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.
18. 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.
19. Recovery
• When removing refrigerant from
a system, either for service 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
numbers 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.
• The recovery equipment shall be
in good working order with a set of
instructions concerning the equipment
that is at hand and shall be suitable for
the recovery of flammable refrigerants.
In addition, a set of calibrated weighing
scales shall be available and in good
working order.
• Hoses shall be complete with leak-
free disconnect couplings and in
good condition. Before using the
recovery machine, check that it is in
satisfactory working order, has been
properly maintained and that any
associated electrical components
are sealed to prevent ignition in
the event of a refrigerant release.
Consult manufacturer if in doubt.
• The recovered refrigerant shall be
returned to the refrigerant supplier
in the correct recovery cylinder, and
the relevant Waste Transfer Note
arranged. Do not mix refrigerants
in recovery units and especially
not in cylinders.
• If compressors or compressor oils
are to be removed, ensure that they
have been evacuated to an acceptable
