Can this cooker hood be used in re-circulation mode?

Yes. The extraction system can be ducted out or used in re-circulation mode. Compatible charcoal filters, including universal and regenerable types, are available as accessories.

What are the minimum installation heights above the hob?

The minimum distance from a gas hob is 750 mm, and the minimum distance from an electric hob is 650 mm.

How many speeds does the hood have and is there an intensive setting?

The hood has three speeds plus an intensive speed. The intensive/turbo setting is intended for situations when extra fast extraction is required.

What is the energy efficiency class and annual energy consumption?

The energy efficiency class is A, with an annual efficiency consumption (AEChood) of 55 kWh/year.

How does the 24h air filter function work?

When selected, the 24h function refreshes the air for about 10 minutes every hour over a 24 hour period, operating at minimum speed and at an imperceptible noise level.

How will I know when to change the filters?

The hood has warning light(s) that advise when filters need changing. It is equipped with aluminium anti-grease filters, and compatible charcoal filters are available separately.
