Installing the thermal insulation

The thermal insulation is best installed at a room
temperature. Lightly tapping the thermal insulation
towards the two ends makes it easier to bring the ends
together.

If you are using a booster heater, remove the perforated recess from the
thermal insulation ( Fig. 12, page 52).
5.5.2

Installing the 120 mm thermal insulation

We recommend completing the installation and
tightness test before installing the thermal insulation.

Environmental protection/disposal

Environmental protection is a key commitment of the Bosch Group.
Quality of products, efficiency and environmental protection are equally
important objectives for us. All legislation pertaining to the
environmental protection is strictly observed. To protect the
environment we use the best possible technology and materials, subject
to economic considerations.
Packaging
Where packaging is concerned, we participate in country-specific
recycling systems that ensure optimal recycling. All of our packaging
materials are environmentally compatible and can be recycled.
Old appliance
Old appliances contain materials that should be recycled.
The relevant assemblies are easy to separate, and all plastics are
identified. In this manner the individual components are easily sorted
and added into the recycling and disposal systems.
