ENGLISH
Decommissioning
Before carrying out this procedure, it is essential that the technician is completely familiar
with the equipment and all its detail. It is recommended good practice that all refrigerants
are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be
taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that
electrical power is available before the task is commenced.
Become familiar with the equipment and its operation.
Isolate system electrically.
Before attempting the procedure, ensure that: mechanical handling equipment is available, if
required, for handling refrigerant cylinders; all personal protective equipment is available and
being used correctly; the recovery process is supervised at all times by a competent person;
recovery equipment and cylinders conform to the appropriate standards.
Pump down refrigerant system, if possible.
If a vacuum is not possible, place a manifold so that refrigerant can be removed from various
parts of the system.
Make sure that cylinder is situated on the scales before recovery takes place.
Start the recovery machine and operate in accordance with the instructions in this manual.
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.
Labelling
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 equipment stating the
equipment contains flammable refrigerant.
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 completed 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 completed 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 the
Technical Support Service of Cecotec if in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recover
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.
