units
4.4.1.1
Setting up the AHU or AHU casing units
Placement of AHU casing units
The arrangement of the individual AHU casing units
is shown in the drawings on the individual delivery
units.
Installation accessories
Installation accessories are packed separately in an
accessory pack which is normally located in the fan
chamber.
1.
Assemble the AHU casing units as closely as pos-
sible to the installation site in accordance with the
installation sequence, Fig. 11 . Also pay attention
to the local interfaces, e.g. to drainage and water
connections.
2.
Remove all foil packaging.

3.
Perimeter seals ( Fig. 11 /1) are fitted at the con-
nection points of the AHU casing units. The seal is
only located on one AHU casing unit in each case,
the casing unit to be connected to it has no seal
Check that the seals are complete and intact and
that they seal properly.
Deformed seals
Compressed seals will recover fully to their
original state about 60 minutes after the trans-
port protection devices have been removed.

Units with anti-vibration frames
(optional)
If the air handling unit is equipped with an anti-
vibration frame (Vibration Baseframe - AVBF
optional), no special measures are required for
insulation of structure-borne noise. This instal-
lation step can be omitted in this case.
If the air handling unit is installed on a surface with
a high coefficient of friction (e.g. rubber or elas-
tomer sheets), positioning can be made consider-
ably easier by using slide plates.
To do this, insert the slide plates ( Fig. 12 /1) pro-
vided by the customer between the base frame
and the surface ( Fig. 12 /2).
