11. Disposal and recycling

Transport package disposal
The package protects the appliance against damage
during transport. Packing materials are usually cho-
sen depending on their environmental friendliness
and disposal method and can therefore be recycled.
Returning the package to material circulation saves
raw materials and reduces waste disposal costs.
Parts of packages (e.g. foils, styropor®) can be dan-
gerous to children. Risk of suffocation! Keep parts of
packages away from children and dispose them as
soon as possible.
The unit and its accessories are made of various ty-
pes of material, such as metal and plastic. Defective
components must be disposed of as special waste.
Ask your dealer or your local council.
