Noise emissions from the ventilation unit
It is not recommended to install the ventila-
tion unit in the living area, kitchen or
bathroom as the noise emissions exceed
35 dB (A).
Recommendation: Install the ventilation unit
in a room that has a sufficient level of sound
insulation from the remaining living area.
Designing the air channels
Observe the prescribed sound
NOTICE
pressure level of < 25 dB (A)
in living areas and < 30 dB (A)
in functional areas. Silencers
must be installed in the
ventilation channels.
Recommendation: Install telephony sound
absorbers to reduce the sound transfer
between the individual rooms.
9.4 Condensation run-off
Condensation is formed during heat recovery
that has to be correctly extracted through the
condensation run-off (see Chapter 9.5,
Item F).
Release the 2 quick-release clips and open
the front shutter.
Remove the front cover (6 screws), see
Chapter 6.3.1.
After removing the yellow protective cap,
connect a ¾" drain hose to the conden-
sation run-off connections and to a siphon.

Water seal head
min. 50 mm
The siphon (see figure) needs a
NOTICE
water seal head of at least
50 mm. Install an open drip
funnel with another siphon at
the drainage system, to
receive the condensation. This
disconnects the ventilation unit
from the drainage system and it
prevents a build up of germs at
the unit.
It is not permitted to install
NOTICE
several siphons one after the
other without duct separation.
If there is high humidity in the room where
the unit is installed, insulate the drain hose
and the condensation run-off connection to
avoid condensation.
Now pour water into the condensation run-
off in the ventilation unit. Check that the
connection is not leaking.
Fix the front cover in place and close the
front shutter, see Chapter 6.3.1.
