Description of functions The following functions are available on your ventilation hood, depending on the model: Vented mode Recirculation mode The recirculation mode requires a recir‐ culation kit and OdorFree Charcoal Fil‐ ter (available as optional accessories, see "Technical Data" for more informa‐ tion) The air is drawn in and cleaned by the grease filters and directed outside. Non-return flap A non-return flap in the ducting pre‐ vents the exchange of inside and out‐ side air from occurring when the venti‐ lation hood is not in use. The flap is closed when the ventilation hood is turned off. When the ventilation hood is turned on, the non-return flap opens so that the exhaust air can be transported outside without any obstruction. A non-return flap has been provided with the hood in case your ducting does not have one. It is inserted into the outlet duct collar of the fan. The air is drawn in and first cleaned by the grease filters and then by an Odor‐ Free Charcoal Filter. The cleaned air is then recirculated back into the kitchen. 14
