  • Keep the instruction manual and the product information safe for future reference or for the next owner.
  • Do not connect the appliance if it has been damaged in transit.

1.2 Intended use

This appliance is designed only to be built into kitchen units. Read the special installation instructions.
The appliance can only be used safely if it is correctly installed according to the safety instructions. The installer is responsible for ensuring that the appliance works perfectly at its installation location.
Only use this appliance:

  • For extracting cooking vapour.

  • in private households and in enclosed spaces in a domestic environment.

  • up to an altitude of max. 2000 m above sea level.
    Do not use the appliance:

  • With an external timer.

1.3 Restriction on user group
This appliance may be used by children aged 8 or over and by people who have reduced physical, sensory or mental abilities or inadequate experience and/or knowledge, provided that they are supervised or have been instructed on how to use the appliance safely and have understood the resulting dangers.
Do not let children play with the appliance. Children must not perform cleaning or user maintenance unless they are at least 15 years old and are being supervised.
Keep children under the age of 8 years away from the appliance and power cable.

1.4 Safe use

WARNING  ‒ Risk of suffocation!
Children may put packaging material over their heads or wrap themselves up in it and suffocate.

  • Keep packaging material away from children.

  • Do not let children play with packaging material.
    Children may breathe in or swallow small parts, causing them to suffocate.

  • Keep small parts away from children.

  • Do not let children play with small parts.

WARNING ‒ Risk of poisoning!

Risk of poisoning from flue gases being drawn back in. Room-air-dependent heat-producing appliances (e.g. gas, oil, wood or coal operated heaters, continuous flow heaters or water heaters) obtain combustion air from the room in which they are installed and discharge the exhaust gases into the open through an exhaust gas system (e.g. a chimney). With the extractor hood switched on, air is extracted from the kitchen and the adjacent rooms. Without an adequate supply of air, the air pressure falls below atmospheric pressure.
Toxic gases from the chimney or the extraction shaft are sucked back into the living space.

  • Always ensure adequate fresh air in the room if the appliance is being operated in exhaust air mode at the same time as a room-air-dependent heat-producing appliance is being operated.
  • It is only possible to safely operate the appliance if the pressure in the room in which the heating appliance is installed does not fall below 4 Pa (0.04 mbar). This can be achieved whenever the air needed for combustion is able to enter through openings that cannot be sealed, for example in doors, windows, incoming/exhaust air wall boxes or by other technical means. An incoming/exhaust air wall box alone is not sufficient to ensure compliance with the limit.
  • In any case, consult your responsible chimney sweep. They are able to assess the house’s entire ventilation setup and will suggest the suitable ventilation measures to you.
  • Unrestricted operation is possible if the appliance is operated exclusively in circulating-air mode.

WARNING ‒ Risk of fire!

Fatty deposits in the grease filters may catch fire.

  • Never operate the appliance without a grease filter.

  • Clean the grease filters regularly.

  • Never work with naked flames close to the appliance (e.g. flambéing).

  • Do not install the appliance near a solid fuel heating appliance (e.g. wood- or coalburning) unless the heating appliance has a sealed, non-removable cover. There must be no flying sparks.
    Hot oil or grease ignites very quickly.

  • Always supervise hot oil and fat.

  • Never extinguish burning oil or fat with water. Switch off the cooking zone.
    Extinguish flames carefully using a lid, fire blanket or something similar.
    When gas burners are in operation without any cookware placed on them, they can build up a lot of heat. A ventilation appliance installed above the cooker may become damaged or catch fire.

  • Only operate the gas burners with cookware on them.
    Operating multiple gas hobs at the same time generates a great deal of heat. A ventilation appliance installed above the cooker may become damaged or catch fire.

  • Only operate the gas hobs with cookware on them.

  • Select the highest fan setting.

  • Never operate two gas hobs simultaneously on the highest flame for longer than 15 minutes. Two gas hobs correspond to one large burner.

16.1 Included with the appliance
After unpacking all parts, check for any damage in transit and completeness of the delivery.

16.2 Dimensions
You will find the dimensions of the appliance here

16.3 Safety clearances
Comply with the safety clearances for the appliance.

16.4 Secure installation
Follow these safety instructions when installing the appliance.
WARNING ‒ Risk of poisoning!
Risk of poisoning from flue gases being drawn back in. Room-air-dependent heat-producing appliances (e.g. gas, oil, wood or coaloperated heaters, continuous flow heaters or water heaters) obtain combustion air from the room in which they are installed and discharge the exhaust gases into the open through an exhaust gas system (e.g. a chimney). With the extractor hood switched on, air is extracted from the kitchen and the adjacent rooms. Without an adequate supply of air, the air pressure falls below atmospheric pressure.
Toxic gases from the chimney or the extraction shaft are sucked back into the living space.

▶ Always ensure adequate fresh air in the room if the appliance is being operated in exhaust air mode at the same time as a room-air-dependent heat- producing appliance is being operated.
▶ It is only possible to safely operate the appliance if the pressure in the room in which the heating appliance is installed does not fall below 4 Pa (0.04 mbar). This can be achieved whenever the air needed for combustion is able to enter through openings that cannot be sealed, for example in doors, windows, incoming/exhaust air wall boxes or by other technical means. An incoming/exhaust air wall box alone is not sufficient to ensure compliance with the limit.
▶ In any case, consult your responsible chimney sweep. They are able to assess the house’s entire ventilation setup and will suggest the suitable ventilation measures to you.
▶ Unrestricted operation is possible if the appliance is operated exclusively in circulating-air mode.
Risk of poisoning from flue gases being drawn back in.
▶ If an extractor hood with an open-flued heat production source is installed, the power supply for the extractor hood must be provided with a suitable safety switch.
Risk of poisoning from flue gases being drawn back in.
▶ Do not emit the exhaust air into a smoke or exhaust gas flue that is in operation.
▶ Do not emit the exhaust air into a shaft that is used to ventilate installation rooms for heat-producing appliances.
▶ If the exhaust air is to be conveyed into a smoke or exhaust gas flue, you must obtain the consent of the heating engineer responsible.
WARNING ‒ Risk of suffocation!
Children may put packaging material over their heads or wrap themselves up in it and suffocate.
▶ Keep packaging material away from children.
▶ Do not let children play with packaging material.
WARNING ‒ Risk of fire!
The grease deposits in the grease filter may catch fire.
▶ Never work with naked flames close to the appliance (e.g. flambéing).
▶ Do not install the appliance near a heatproducing appliance for solid fuel (e.g. wood or coal) unless a closed, non-removable cover is present. There must be no flying sparks.
▶ The specified safety clearances must be complied with in order to prevent a build-up of heat.
▶ Observe the specifications for your cooking appliances. If the installation instructions for the cooking appliances specify a different clearance, the larger of the two must always be provided for. If gas hobs and electric hobs are operated together, the largest specified clearance applies.
WARNING ‒ Risk of injury!
Components inside the appliance may have sharp edges.
