DISPOSAL PROCEDURE
Once the unit comes to the end of its life cycle and needs to be removed or replaced, the following operations are recommended:
• the refrigerant has to be recovered by trained people and sent to proper collecting centre;
• the compressors’ lubricating oil has to be collected and sent to proper collecting centre;
• the frame and the various components, if not serviceable any longer, have to be dismantled and divided according to their
nature, particularly copper and aluminium, which are present in conspicuous quantity in the unit. These operations allow easy
material recover and recycling process, thus reducing the environmental impact.
