6.1 Unit installation

Wall installation KWK EC
NOTICE!
Installation and commissioning should only be
performed by trained specialists.
The unit is attached by means of mounting holes in
the housing while also taking account of the air
outlet side located in the upper part of the unit.
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
Wall installation KWK EC (DM)
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
Installing the feet / air inlet plinth (accessory)
only for KWK
If the feet or plinth available as accessories (KWK)
are to be used for units for wall or ceiling mounting,
these must be installed before the unit is installed.
Follow the separate installation instructions.
NOTICE!
The air ducting must then be selected such that
no short-circuit can occur on the air side.
NOTICE!
If the unit is not mounted positively, vibration
can occur.

Selecting the hydraulic connection
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.
2-conductor system for cooling and heating
As the 2-conductor system must cool and heat
equally, for reasons of convection during winter
operation, a valve assembly is stipulated for all
installation methods for this system operation to
avoid undesirable heat emission.
4-conductor system for cooling and heating
As the 4-conductor system must cool and heat
equally, two valve assemblies are stipulated for this
system operation for the cooling and heating reg-
ister.
Connection of the medium pipings
n The connection of the lines on-site takes place
on the rear or underside of the unit.
n For the purpose of servicing, connections must
be equipped with shut-off valves and the
medium flow rate adjusted using valves for
hydronic balancing.
n Additional automatic bleed valves are to be
provided in the supply and return flow at the
installation's highest point.
n The medium pipings may not exert any struc-
tural load on the unit.
n The line connections may not generate any
thermal or mechanical stresses on the unit. If
necessary, cool the piping or support with the
second tool.
