Decommissioning - Vortice DEUMIDO 10 EVO Instruction Booklet

ENGLISH

Decommissioning

• Become familiar with the equipment and its operation.
• Isolate system electrically.
• Before attempting the procedure, ensure that:
1.mechanical handling equipment is available, if required, for handling refrigerant cylinders;
2.all personal protective equipment is available and being used correctly;
3.the recovery process is supervised at all times by a competent person;
4.recovery equipment and cylinders conform to the appropriate standards.
• Pump down refrigerant system, if possible.
• If a vacuum is not possible, make 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 manufacturer's instructions.
• 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.
• Equipment shall be labelled stating that it has been de-commissioned 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.
Ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of
cylinders for holding the total system charge are available. 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.
