fi 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

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.
• 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
fl ammable refrigerants.
• Make sure the recovery equipment
is not a potential ignition source and
is suitable for the refrigerant you are
using.

weighing scales shall be available
