5.11.2. Mounting air duct with 90 °
Air intake side same as the corner installation.
The channel and the 90 ° bend are mounted the same
way as for the straight channel installation. See point
“Mounting straight air duct”
Also, the air duct wall connection is mounted as de-
scribed in the point “Installation straight air duct”.
In this case, the entire air duct wall connection (in-
cluding both
fl
anges) lies within the wall recess.
One side of the 90 ° arc lies directly in the wall.
After the channel has been set up, it must be insu-
lated with the provided insulation.

Then the wall connection duct has to be
fi
lled cleanly
and airtight (see also point “Installation straight air
duct”)
On the outside wall, the
weather-shield grille
(or
mesh grille) is mounted directly in the insulation of
the wall opening by the provided dowels. Finally, the
foamed area of the wall breakthrough must be cov-
ered with the panel.
The air outlet is usually about 4-5 K un-
der the intake air temperature in heating
mode. Thus, the blown air sinks and
moves down to the lowest point. This is
especially important when installing with
rising or falling terrain.
The air ducts are supplied including
mounting material (screws, washers,
nuts)!
