9 Disposing of the appliance
The appliance contains some reusable materials
and should be disposed of properly - not simply
with unsorted household refuse. Appliances which
are no longer needed must be disposed of in a
professional and appropriate way, in accordance
with the current local regulations and laws.
When disposing of the appliance, ensure that the refrigeration
circuit is not damaged to prevent uncontrolled escape of the
refrigerant it contains (data on type plate) and oil.
