10.7 ENVIRONMENTAL PROTECTION

The law implementing the regulations [reg. EEC 2037/00] which govern the use of stratospheric ozone-

depleting substances and greenhouse gases bans the dispersal of refrigerant gases in the environment

and requires whoever is in their possession to recover them and, at the end of their useful life, either to

return them to the dealer or take them to a suitable waste disposal facility.

The refrigerant HFC R410A is not harmful to the ozone layer but is included among the substances

responsible for the greenhouse effect and thus falls within the scope of the aforesaid regulations.

Therefore, special care should be taken when carrying out maintenance work to

minimise refrigerant leaks.

11 DECOMMISSIONING THE UNIT

When the unit has reached the end of its working life and needs to removed and replaced, a series of

operations should be carried out:

- the refrigerant gas it contains should be recovered by specialised personnel and sent to a waste

collection facility;

- the lubricating oil in the compressors should also be recovered and sent to a waste collection facility;

- if they cannot be reused, the framework and components should be scrapped and separated according

to the type of material: this applies especially for the considerable quantities of copper and aluminium

present in the unit.

This will make the job of waste collection, disposal and recycling facilities easier and minimise the

environmental impact of such processes.
