Operation
The ventilation system can be opened or closed via the inner cover.
For the ventilation device to function correctly, the inner cover of your ventilation device must be
open.
To reduce noise and direct the air flow, the inner cover panel can be moved to a narrower posi
-
tion. 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 open.
