1 Safety
1.7 Risk of being burned or scalded by
hot components
▶ Only carry out work on these components
once they have cooled down.
1.8 Material damage due to unsuitable
installation surface
The installation surface must be even and
have sufficient load-bearing capacity to sup-
port the operating weight of the product. An
uneven installation surface may cause leaks
in the product.
If the installation surface does not have suffi-
cient load-bearing capacity, the product may
become detached and fall off.
There is a risk of death if the connections are
subject to leaks.
▶ Make sure that the product is positioned
flush against the installation surface.
▶ Ensure that the installation surface has
sufficient load-bearing capacity to bear the
operating weight of the product.
1.9 Risk of injury due to the heavy weight
of the product
▶ Make sure that the product is transported
by at least two people.
1.10 Risk of material damage caused by
frost
▶ Do not install the product in rooms prone
to frost.
1.11 Risk of material damage caused by
using an unsuitable tool
▶ Use the correct tool.
1.12 Risk of material damage caused by
water that is too hard
Water that is too hard may impair the sys-
tem's functionality and cause damage in a
short period of time.
▶ Ask your local water company about the
water hardness.
▶ When deciding whether the water used
must be softened, follow the national regu-
lations, standards, directives and laws.
▶ In the installation and maintenance instruc-
tions for the product that your system com-
4

stored at the installation site.
▶ Ensure that the air is not routed through an
old hearth.
▶ If you are installing the product in
hairdressing salons, painter's or joiner's
workshops, cleaning businesses or similar
locations, choose a separate installation
room in which an air supply is ensured that
is technically free of chemical substances.
▶ If the air in the room in which the product
is installed contains aggressive vapours or
dust, ensure that the product is sealed and
protected.
1.14 Risk of poisoning caused by
insufficient air supply
Condition: Open-flued operation
