For access to the storage tank, it is recommended that the following clearances are
observed:

The packaging prevents damage to the appliance during transport.
The packaging material chosen is environmentally friendly, recyclable
and relatively easy to dispose of in an environmentally aware way.
Old end-of-life appliances contain materials that need to be recycled. When disposing
of old devices that have reached the end of their service life, you
should take account of local legislation relating to waste disposal.
You must therefore never dispose of your old appliance together
with regular waste, but should and it into a municipal waste
collection depot for electrical and electronic equipment. Ask your
dealer/installation engineer for advice if necessary. The old
appliance must be stored out of reach of children.
