Hello

I am trying to remove the kitchen ventilator filter for cleaning -- but can't figure out how to do so.

I see only two screws on the sides of the top frame that seem to hold the thing fast. Removing the screws seems release the whole ventilator unit from the frame.

Is there a quick way to remove the ventilators for cleaning, or one has to remove the ventilator from the frame as well?

Many thanks.
