4.1 General installation information
Before installation
Before you install the unit, take suitable precautions to
protect air distribution components from contamination
during installation
⇨
VDI 6022.
If this is not possible, at least cover the unit or take
other precautions to protect it from contamination. In
this case you have to ensure that the unit cannot be
started.
Ensure that all components are clean before you install
them. If necessary, clean them thoroughly. If you have
to interrupt the installation procedure, protect all open-
ings from the ingress of dust or moisture.
Installation information
Install the ventilation unit preferably in a thermally
insulated, low-leakage building.
Frost free and dry installation location.
Installation and connections to be performed by
others; fixing, connection and sealing material to be
provided by others
Install the unit only on structural elements that can
carry the load of the unit.
Use only certified fixing systems.
The room facing side of the unit must remain com-
pletely accessible for maintenance and cleaning.
Air connection
Two openings in the façade are required, one for out-
door air and one for exhaust air. The ventilation unit is to
be sealed to the external wall with a factory fitted closed
cell perimeter seal. The surfaces onto which the outdoor
air and exhaust air openings are sealed must be even.
Ensure that the unit is correctly sealed to the wall.
The outdoor air and exhaust air openings have to be
protected against the effects of weather (by others).
Secondary air units are not to be connected to the
façade.

The ventilation unit is to be installed and fixed on the
inside of an external wall, floor-standing. Façade open-
ings for outdoor air and exhaust air are required (see
approval drawing). Screws and wallplugs for fixing the
ventilation unit are not included in the supply package,
but have to be selected by others and fit for the wall.
Install the unit in such a way that it rests completely on
its feet. Use the fixing points only as an additional
means of securing the unit against tipping.
Make sure that the unit can be connected to the pipe-
work and to the mains supply.
1.
Place the unit in such a way that the wall side
(Fig. 9/A) faces the wall. The openings for the air
(Fig. 9/2 and Fig. 9/4) must be aligned with the
prepared openings in the external wall; adjust the
feet if necessary.
2.
Use suitable screws (
∅
6 mm) for the provided
fixing holes (Fig. 9/1) to fix the unit to the external
wall.
3.
Adjust the feet (Fig. 9/5), then tighten the nuts.
Height-adjustable air distribution connector (only
