Important safety information

Warning – Danger of suffocation!
Packaging material is dangerous to children. Never allow children to play with packaging material.
Warning – Danger of death!
Risk of poisoning from flue gases that are drawn back in.
Always ensure adequate fresh air in the room if the appliance is being operated in exhaust air mode at the same time as the room-independent heat-producing appliance is being operated.

Room air-dependent heat-producing appliances (e.g. gas, oil, wood or cooperated 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 air through an exhaust gas system (e.g. a chimney).
In combination with an activated vapor extractor hood, room air is extracted from the kitchen and neighboring rooms – a partial vacuum is produced if not enough fresh air is supplied. Toxic gases from the chimney or the extraction shaft are sucked back into the living space.

• Adequate incoming air must therefore always be ensured.
• An incoming/exhaust air wall box alone will not ensure compliance with the limit.

Safe operation is possible only when the partial vacuum in the place where the heat-producing appliance is installed does not exceed 4 Pa (0.04 bar). This can be achieved when 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. In any case, consult your responsible Master Chimney Sweep. He is able to assess the house’s entire ventilation setup and will suggest suitable ventilation measures to you. Unrestricted operation is possible if the vapor extractor hood is operated exclusively in the circulating-air mode.
Warning – Risk of fire!

• Fatty deposits in the grease filter may catch fire. Regularly clean the grease filter. Never operate the appliance without a grease filter. Risk of fire!
• 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 heat-producing appliance for solid fuel (e.g. wood or coal) unless a closed, nonremovable cover is available. There must be no flying sparks. Risk of fire!
• Hot oil and fat can ignite very quickly. Never leave hot fat or oil unattended. Never use water to put out burning oil or fat. Switch off the hotplate. Extinguish flames carefully using a lid, fire blanket, or something similar. Risk of fire!
• 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. Risk of fire!
• Operating several gas burners at the same time gives rise to a great deal of heat. A ventilation appliance installed above the cooker may become damaged or catch fire. Never operate two gas burners simultaneously on the highest flame for longer than 15 minutes. One large burner of more than 5 kW (wok) is equivalent to the power of two gas burners.

Warning – Risk of burns!

• The accessible parts become very hot when in operation. Never touch hot parts. Keep children at a safe distance. Risk of burns!
• The appliance becomes hot during operation. Allow the appliance to cool down before cleaning.

Warning – Risk of injury!

• Components inside the appliance may have sharp edges. Wear protective gloves. Risk of injury!

Environmental protection

Your new appliance is particularly energy-efficient. Here you can find tips on how to save even more energy when using the appliance, and how to dispose of your appliance properly.
Saving energy

• During cooking, ensure that there is a sufficient supply of air to enable the extractor hood to work efficiently and with a low level of operating noise.
• Adjust the fan speed to the amount of steam produced during cooking. Only use intensive mode when required. The lower the fan speed, the less energy is consumed.
• If cooking produces large amounts of steam, select a higher fan speed in good time. If the cooking steam has already spread around the kitchen, the extractor hood will need to be operated for longer.
• Switch off the extractor hood if you no longer require it.
• Switch off the lighting if you no longer require it.
• Clean and (if required) replace the filter at regular intervals in order to increase the effectiveness of the ventilation system and to prevent the risk of fire.
• Put the lid on to reduce cooking steam and condensation.

Environmentally-friendly disposal
Dispose of packaging in an environmentally-friendly manner.
This appliance is labeled in accordance with European Directive 2012/19/EU concerning used electrical and electronic appliances (waste electrical and electronic equipment – WEEE). The guideline determines the framework for the return and recycling of used appliances as applicable throughout the EU.
