Operation
5.1
Opening/closing the inner cover
For the ventilation unit to function correctly, the inner cover of your ventilation device must be open.
Close the inner cover if you take the ventilation device out of operation. Sealing prevents unwanted
air exchange, e.g. cold air flowing into the living area.
In certain situations, e.g. accidents involving smoke or escaping gases, it is necessary to lock
windows and doors. In this case, your ventilation devices must also be disconnected from the
power supply and the inner covers closed.
Open the inner covers again before you switch on the ventilation device.
5.2
Tilting the inner cover
To reduce noise and direct the air flow, the Flair inner cover panel can be tilted up or down. The inner
cover is closed on the tilted side and the air flow is directed in the open direction. This causes the
sound pressure level to decrease. The air flow is reduced if the inner cover is only partially opened.
Requirements: The inner cover is open.
►
Slide the inner cover panel onto the lower (upper)
spacers in the direction of the base plate.
The inner cover panel is tilted downwards
(upwards).
The flow rate will be directed upwards
(downwards).
The sound pressure level is reduced.
Requirements: The cover is fitted.
Closing the inner cover:
►
Push the inner cover panel towards the interior
wall up to the bas plate.
Opening the inner cover:
►
Pull the inner cover panel forwards until
you feel all four spacers snap into place.
You have opened/closed the inner cover.
