DECOMMISSIONING
Once the unit has reached the end of its life cycle and needs to be replaced, the following operations are
recommended:
•
the refrigerant has to be recovered by trained personnel and sent to proper collection centres;
•
the compressors’ lubricating oil has to be collected and sent to proper collection centres;
•
the electronic components, such as regulators, driver boards and inverters, must be disassembled and
sent to proper collection centres;
•
the structure and the different components, if unusable, must be scrapped and divided according to their
nature; there is especially a good amount of copper and aluminium in the machine.
These operations allow easy material recovery and the recycling process, thus reducing the environmental
impact.
