Heating air duct (example)
Conducting the combustion air
The combustion air must be drawn in from the out-
side (not from the passenger compartment or boot).
The combustion air intake must be arranged in such
a manner that it cannot draw in any exhaust gas. Do
not position the suction opening of the combustion
air hose in the opposite direction of the air-stream.
Position the combustion air hose in such a manner
that it cannot become clogged with dirt or snow, and
any water that may have entered the hose can freely
drain out again.
At the inlet of the combustion air hose, the terminal
sleeve with web provided for must be mounted
(statutory regulation).
Please note!
Small arrows indicating the flow direction (see
drawing) have been cast into the connecting pieces
so that they can be correctly assigned to
combustion air and exhaust gas (see below).
Danger of burns or injury!
The hoses of the hot air duct and their hot air
exhaust must always be laid and mounted in such
a manner that no thermal danger arises from them
for man, beast or heat-sensitive material due to
radiation / contact or due to hot air being directly
blown onto them.
The exhaust hood must be pushed on at the hot air
exhaust side.
If no air hoses have been mounted, a protective grille
must be pushed on at the hot air suction side and
exhaust side to avoid injuries due to the hot air fan
and/or burns due to the heat exchanger.
High temperatures occur on the hot air duct during
and also immediately after heating operation. Avoid
thus any work in the area of the hot air duct during
heating operation. In such a case, switch off the
AIRTRONIC
beforehand and wait until all parts have
completely cooled down.
If necessary, wear protective gloves.
The heating air intakes have to be arranged in such a
manner that, under normal operating conditions, they
cannot draw in exhaust fumes from the vehicle’s engine
and from the
AIRTRONIC
, and that the heating air
cannot be polluted by dust, salt fog, etc.
In recirculation mode, the recirculated air inlet has to
be positioned in such a manner that the outflowing hot
air cannot be directly drawn in again.
When checking the functions, the mean exhaust
temperature after approx. 10 minutes of operation
measured approx. 30 cm from the air outlet should
not exceed 110 °C at an intake temperature of
approx. 20 °C.

Please note!
When connecting up parts conducting air, please
observe the device guide number in the technical
specifications (see page 6)!
In the case of a possible malfunction due
to overheating, heating air temperatures of up
to max. 180 °C and surface temperatures of up
to max. 150 °C may occur locally immediately prior
to malfunction cut-off.
For this reason, only heat-resistant hot air hoses
approved by us may be used for the hot air duct!
ATTENTION!
