General information

• Read this instruction manual carefully.
• Only a licensed expert may connect the appliance.
• Switch off the power supply before carrying out any work.
• Never use this appliance in boats or in vehicles.
• Follow the worktop manufacturer’s recommendations.

Safe installation
Follow these safety instructions when installing the appliance.

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.
WARNING ‒ Danger: Magnetism!
The appliance contains permanent magnets. They may affect electronic implants, e.g. pacemakers or insulin pumps.

• Persons with electronic implants must stand at least 10 cm away from 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 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!
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 heat-producing appliance for solid fuel (e.g. wood or coal) unless a closed, non-removable cover is present. There must be no flying sparks.

WARNING ‒ Risk of injury!
Changes to the electrical or mechanical assembly are dangerous and may lead to malfunctions.

• Do not make any changes to the electrical or mechanical assembly.
  Parts that are accessible during installation may have sharp edges and may lead to cutting injuries.

• Wear protective gloves.

The appliance is heavy.

• To move the appliance, two people are required.
• Use only suitable tools and equipment.

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 poisoning!
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.

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.
