e) If a vacuum is not possible, make a manifold so that refrigerant can be removed
from various parts ofthe system.
PT
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
IT
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.
EL
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
PL
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.
17 .Labelling
RO
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
EN
equipment stating the equipment contains flammable refrigerant.
18.Recovery
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 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
