For all work the
safety instruc-
tions cited in point 3.2
of these
instructions have to be heeded!
10.2 DEVICE INSTALLATION
The following devices must be available in
the installation room:
• Air line connections for the supply,
extract, outdoor air and exhaust air
• An electrical mains connection of
230 V/50 Hz, fuse 16 A
• Condensate drainage line with an
effective odour trap (siphon)
All on-site work (drainage, floor struc-
ture etc.) must be completed prior to
installation of the ventilation unit.
After connection of the air lines to the
ventilation unit, the unit is fixed and can
no longer be moved.
The outdoor air and exhaust air lines,
for example, between the ventilation
unit and roof leadthrough, have to be
sufficiently insulated for energy reasons
and for the purpose of avoiding conden-
sate formation. No condensate must be
allowed to form on the air lines or in the
roofing.
In the case of line routes outside of the-
thermally insulated building shell these
routes have to be sufficiently insulated in
the cold area.
To ensure proper and functional system
operation, suitable insulation,sound in-
sulation and installation materials, con-
forming to the planningdocuments and
technical data, such as adequate sized
sound absorbers,supply air and extract
air valves, overflow openings etc. should
beprovided for. In principle, all device
connection pieces should be fittedwith
sound absorbers to ensure an appropri-
ate sound level in the living area.
Air line leadthroughs through walls or
ceilings have to be made so that they
do not resonate due to structure-borne
noise.
To protect against coarse contamination,
for example, leaves, insects etc., a fine
mesh wire grating has to be provided as
a prefilter directly at the central outdoor
air intake point. The protective grating
has to be checked and, if necessary,
cleaned at regular intervals, in particular
in the spring and autumn. Inspection
openings should be provided in the air
line system to facilitate cleaning and
maintenance of the system.
