Use
thermally insulated ducts
for ODA
and EHA.
Use at least 1 m of fl exible or rigid
silencer
.
Rigid = low emission from housing
Flex = low noise from duct
Duct diameter
:
160 mm to 250 m³/h / 180 mm from 250 m³/h and
over or equivalent subject to calculation (e.g. with cast-
in ducting)
Make sure that the total counter pressure in the ducts
is as low as possible (preferably ≤ 150Pa) and that the
airspeed in every duct
does not exceed 3 m/s
.
Hang the unit
level
.
Allow suffi cient space for the
condensate drain.
Use
silencers between
rooms
to prevent voices from
carrying.
For wall mounting: wall
with minimum mass density
of 200 kg/m²
. Plaster blocks or
metal struts are not adequate!
Use a mounting plinth if the wall is
not sufficient.
Use
brackets
with a rubber
inlay
to reduce
transmission of
vibration.
Keep resistance down
to a minimum.
Avoid as much as
possible the use of
curves.
Avoid sharp
angles. Avoid
bumps
and dirt
in the ducts.
Select a
roof pass-through
with low resistance.
Assure an
airtight
connection by
using tape, clamping strips or tie-
wrap.
Do not use screws.
Place
a cap on any unused connection
opening.
Ensure there is
suffi cient distance
between ODA and EHA cf. EN 13779.

The correct operation of your Duco ventilation system is entirely dependent
on the choice and build quality of the supply and exhaust ducts!
Has the duct system been optimized? Ask
professional advice from your duct supplier. It
saves you time, ensures quality and provides
energetic advantage for the end user!
