Duct system
It is recommended that the ventilation duct system is
made of spiral ducts with rubber ring seal fittings so as to
provide a tight and durable duct system.
There are also other duct systems: Flat metal ducts and
plastic duct systems.
To obtain a satisfactorily low noise level from the unit,
silencers must always be mounted on the supply air and
extract air ducts between the unit and the first supply air
and extract air valves. A silencer on the exhaust air duct
is also recommended.
To prevent the transmission of sound from one room
to another, we recommend always installing a silencer
between the two rooms.
It is recommended that the air speeds in the ducts be
dimensioned low enough so that there is no noise from
the supply air and extract air valves.
When positioning the fresh air and exhaust air roof cowls/
grills,
make sure that the two air flows do not intercept causing
exhaust air to be drawn in again. Minimum spacing: 3 m.
It is recommended that the fresh air grills are placed on
the north or east side of the house to ensure optimum
comfort.
Duct connection
At each duct connection there is a yellow sticker
indicating which ventilation duct is to be connected to
which bushing.
Supply air:
The duct system from the unit to the rooms.
Extract air:
The duct system from the wet rooms to the unit.
Fresh air:
The duct system from the fresh air roof cowls/external
grills to the unit.
Exhaust air:
The duct system from the unit to the exhaust air roof
cowls/external grills.
