Question about UNDERVERK extractor hood in recirculation mode

Hello,

I am currently installing an Underverk extractor hood for recirculation operation. Do I understand correctly that the flap in the picture has to be removed?

Hello, right, in the [Umluftbetrieb] no air from outside can be pushed in and the flap would only further reduce the airflow.

Great, then I did it correctly. Thank you very much for the quick response.
