Operating Modes

You can use this appliance in the air extraction or the
recirculation mode.
Exhaust air mode
The air that is drawn in is cleaned by the
grease filters and conveyed to the
exterior by a pipe system.
Note: Ventilation may not exit through an already
operational smoke or exhaust chimney, nor a duct used
for ventilating furnace installation areas.
• If the ventilation is intended to pass through a smoke
or exhaust chimney that is not in operation, the
responsible area heating inspector must give approval.
• If the ventilation passes through an external wall, use a
telescope wall sleeve.

Operating the Appliance

These instructions apply to several appliance models. It
is possible that individual features are described that do
not apply to your appliance.
Note: Turn the extractor hood on when you start cooking
and switch it off again a few minutes after you have
finished cooking. This is the most effective way to
eliminate cooking vapor.

(after 120 hours of ventilation operation) is indicated on
the display panel:
• Metal grease filter: "clean grease filter" appears on
the display panel.
• Activated carbon filter: "replace charcoal filter"
appears on the display panel.
If you have not yet done so, the metal mesh grease filters
