Disposal
Disposal of the appliance
A crossed-out wheelie bin icon means: Bat-
teries and rechargeable batteries, electrical
or electronic devices must not be disposed of
with household waste. They may contain
substances that are harmful to the environ-
ment and human health.
Consumers must dispose of waste electrical devices,
spent portable batteries and rechargeable batteries
separately from household waste at an official collec-
tion point to ensure that these items are processed
correctly. The product can be returned free of charge
in accordance with the legal requirements, for exam-
ple through a municipal waste disposal company or a
dealer.
Batteries, rechargeable batteries and lamps
that are not permanently installed in waste
electrical equipment and can be removed in
a non-destructive way must be removed and
disposed of separately before disposal of the equip-
ment. Lithium batteries and rechargeable battery
packs of all systems are only to be handed in to the
waste collection points in a discharged state. The bat-
teries must always be protected against short circuits
by taping off the poles.
