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 the exhaust air mode at the same time as 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 the extractor hood is operated exclusively in the circulating-air mode.

Warning – Risk of fire!

• Grease deposits in the grease filter may catch fire. Clean the grease filter at least once a month.  Never operate the appliance without the grease filter.
• 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.
• 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.
• 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 hotplates at the same time generates a great deal of heat. The ventilation appliance may become damaged or catch fire. The ventilation the appliance  must only be combined with gas hotplates that do not exceed the following values:
  – Total maximum output: 9.75 kW
  – Maximum output for a single burner:
  4 kW
  – Total maximum output of rear hobs:
  5.25 kW

Warning – Risk of burns!
The accessible parts become very hot when in operation. Never touch hot parts. Keep children at a safe distance.
Warning – Risk of injury!
■ Components inside the appliance may have sharp edges. Wear protective gloves.
■ Items placed on the appliance may fall down. Do not place any objects on the appliance.
■ The light emitted by LED lights is very dazzling and can damage the eyes (risk group 1). Do not look directly into the switched-on LED lights for longer than 100 seconds.
Warning – Risk of electric shock!
■ A defective appliance may cause electric shock. Never switch on a defective appliance. Unplug the appliance from the mains or switch off the circuit breaker in the fuse box. Contact the after-sales service.
■ Incorrect repairs are dangerous. Repairs may only be carried out and damaged power cables replaced by one of our trained after-sales technicians. If the appliance is defective,  unplug the appliance from the mains or switch off the circuit breaker in the fuse box. Contact the aftersales service.
■ Do not use any high-pressure cleaners or steam cleaners, which can result in an electric shock.

Causes of damage
Caution!
Risk of damage due to corrosion. Always switch on the appliance while cooking to avoid condensation. Condensate can produce corrosion damage.
Always replace faulty bulbs to prevent the remaining bulbs from overloading. Risk of damage due to ingress of humidity into the electronic circuitry. Never clean operator
controls with a wet cloth.
Surface damage due to incorrect cleaning.
Clean stainless steel surfaces in the direction of the grain only. Do not use any stainless steel cleaners for operator controls.
Surface damage due to strong or abrasive cleaning agents. Never use strong and abrasive cleaning agents.
Risk of damage from returning condensate. Install the exhaust duct in such a way that it falls away from the appliance slightly (1° slope).

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 –  WEEK). The guideline determines the framework for the return and recycling of used appliances as applicable throughout the EU.

Operating modes

Exhaust air mode

The air which is drawn in is cleaned by the grease filters and conveyed to the exterior by a pipe system.
Note: The air must not be discharged into a flue that is used for exhausting fumes from appliances burning gas or other fuels (not applicable to appliances that only discharge the air back into the room).

• Before conveying the exhaust air into a non-functioning smoke or exhaust gas flue, obtain the consent of the heating engineer responsible.
• If the exhaust air is conveyed through the outer wall, a telescopic wall box should be used.

Air recirculation

The air which is drawn in is cleaned by the grease filters and an activated carbon filter and is conveyed back into the kitchen.
Note: To bind odors in air recirculation mode, you must install an activated carbon filter. The different options for operating the appliance in air recirculation mode can be found in the brochure. Alternatively, ask your dealer. The required accessories are available from specialist retailers, from customer service or from the Online Shop.
