Installing duct components
The duct components are connected to each other
and to the unit with 4 screws each. The duct com-
ponents must be installed in such a way that they
do not exert any tension on the unit or on the rest
of the duct system. The following points must also
be observed:
n
All duct surfaces must be adequately insulated
against condensation water on site
n
If necessary, all joints must be sealed with suit-
able sealants provided by the customer
n
The effective duct cross-section must not be
reduced
n
The pressure losses on the air side and the
resulting power losses must be kept as low as
possible

Installation
6.1 Unit installation
Ceiling installation
NOTICE!
Installation and commissioning should only be
performed by trained specialists.
NOTICE!
If the unit is not mounted positively, vibration
can occur.
The unit is attached by means of mounting holes in
the housing while also taking account of the air
outlet side directed towards the centre of the room.
1.
Mark the mounting points according to the
mounting's dimensions on structurally
acceptable building components and secure
the unit
2.
Check again that the unit is level
3.
Connect the medium pipes, electrical cables
and condensate drainage line to the unit as
described below

2-conductor cooling system
Wall installation without valve assembly:
when the fan is switched off the flow of air from the
air inlet can be ignored without sacrificing comfort.
In this application case, use of a valve assembly is
not absolutely essential.
Ceiling installation without valve assembly:
a valve assembly must be used in this application
case to prevent the flow of cold air from the air
outlet when the fan is switched off.
Wall installation with valve assembly:
in order to prevent any flow of cold air and severe
condensate formation, for
reasons of comfort
a
valve assembly can be used in this application
case.
Ceiling installation with valve assembly:
in order to prevent any flow of cold air and perma-
nent flow-generated noise, for reasons of comfort a
valve assembly is recommended in this application
case.
