Thelawregulatingtheuseofstratosphericozonedepletingsubstancesprohibitsthereleaseof

refrigerant gases into the environment and obliges owners to recover and return them to the dealer or

take them to special collection centres at the end of their operational life.

The refrigerant contained in the refrigerant circuit is included among the substances subject to special

control regulations provided for by law and must therefore be disposed of as indicated above.

Particular care should be taken during maintenance operations in order to reduce refrigerant leaks as

much as possible.
