Operation
There are two buttons on the front of the extractor hood. One is for the lighting. The other is for the fan. This ensures that the (central) mechanical ventilation system has a chance to do its job properly.

After use
After using the extractor, press the button on the wall again. This prevents the cooker hood from exhausting air unnecessarily. And you also save energy!

Tip: Clean the filter regularly. This can be done easily in soapy water. You can also get a clean filter from your administrator.
