Operation
It works automatically via the central extraction system. The black sliding knob at the bottom of the hood allows you to open or close the exhaust.

Filter
Make sure you clean the filter on the underside of the extractor hood regularly, this will ensure the proper functioning of the extractor hood and prevent nasty smells and deposits in the rest of your home.

Little ventilation while showering?
Then close the outlet of your cooker hood in the kitchen. This provides more extraction in the bathroom.
