11. Recovered refrigerant shall not be charged into
another refrigeration system unless it has been
cleaned and checked.
L L a a b b e e l l l l i i n n g g
Equipment shall be labelled stating that it has been
decommissioned and emptied of refrigerant. The label
shall be dated and signed. For appliances containing
flammable refrigerants, ensure that there are labels on
the equipment stating the equipment contains
flammable refrigerant.
R R e e c c o o v v e e r r y y
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.
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 all appropriate refrigerants including, when
applicable, 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
level to make certain that flammable refrigerant does

not remain within the lubricant. The evacuation
process shall be carried out prior to returning the
compressor to the suppliers. Only electric heating to
the compressor body shall be employed to accelerate
this process. When oil is drained from a system, it shall
be carried out safely.
