• 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 labeled
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 labeled 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
