Labeling; Recovery - OPTIMEO OPC-A01-160HP Manuel D'utilisation

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 unit 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 cyli- nders 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.

10. Labeling

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.

11. 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 is 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
unit, 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.
