Escaping water
NOTICE!
Risk of damage to property from escaping water!
If the water system is not tight, water may escape
and cause considerable damage to property.
–
Ensure that liquids are channelled away and to a
collection device.
4.3 Preventing vibration and structure-
borne noise
Anti-vibration elements or a noise insulating layer
underneath the air handling unit may help to reduce the
transmission of vibration from the air handling unit to the
supporting structure:
If the air handling unit is to be installed on level
ground with no special requirements regarding
structure-borne noise insulation, we recommend
placing rubber or elastomer sheets between the air
handling unit and the foundation.
For noise insulation, compare the requirement to the
sound power level of the air handling unit (see
order-specific data sheet for the air handling unit)
and have the necessary measures determined by
an acoustics engineer.
NOTICE!
Risk of damage to the AHU
Anti-vibration elements or a noise insulating layer
must not affect the structural safety of the AHU.
Ensure the following:
–
Use a sufficient number of anti-vibration ele-
ments and noise insulating layers and place
them correctly as otherwise the frame may sag.
–
Keep in mind that the various AHU casing units
differ in weight; this must not lead to any height
differences in the overall unit.
We recommend you to have noise insulating layers
(including material and layout plan) selected and
sized by an expert company.

4.4.1 Setting up the AHU or AHU casing
units
Checking the seals on AHU casing units
Fig. 10: Seals on AHU casing units
Where two AHU casing units are to be joined, a perim-
eter seal ( Fig. 10 /1) is provided. Note that only one of
the units to be joined is fitted with a seal. The other unit
does not have a seal ( Fig. 10 /2).
Compressed seals will recover fully to their
original state about 60 minutes after the trans-
port protection devices have been removed.
Check that the seals are complete and intact and
that they seal properly.
Setting up AHU casing units
Slide plates ( Fig. 11 /3) considerably simplify the
process of positioning the AHU casing units ( Fig. 11 /1)
on a surface with a high friction coefficient, such as
rubber or elastomer sheets ( Fig. 11 /4).
