Disposal of old air conditioning units
Before disposing of an old air conditioning unit
that is no longer useable, please make sure it's
inoperative, power supply disconnected and safe.
It must be noted that all air conditioning systems
contain refrigerants, which require specialized
waste disposal in accordance with current
legislation. The valuable materials contained in
an air conditioning unit can be recycled. Contact
your local waste disposal centre for proper
disposal of an old unit and contact your local
authority or contractor if you have any questions.
Ensure good environmental awareness by
insisting on an appropriate, anti-pollution
method of disposal.
Disposal of the packaging of your new air
conditioning unit
All the packaging materials employed in the
package of your new air conditioning unit may
be disposed of without any danger to the
environment.
The cardboard box may be broken or cut into
smaller pieces and given to a waste paper
disposal service. The wrapping bag made of
polyethylene and the polyethylene foam pads
contain no fluorochloric hydrocarbon.
All these valuable materials may be taken to a
waste collecting centre and used again after
adequate recycling.
Consult your local authority for the name and
