Operating instructions: Description of appliance Operating modes If the air intake is inadequate, there is a risk of poisoning from combustion gases which are drawn back into the room. An air-intake/exhaust-air wall box by itself is no guarantee that the limiting value will not be exceeded. Note: When assessing the overall requirement, the combined ventilation system for the entire household must be taken into consideration. This rule does not apply to the use of cooking appliances, such as hobs and ovens. Unrestricted operation is possible if the extractor hood is used in recirculating mode – with activated carbon filter. Light Filter grille Operating modes Circulating-air mode:
❑ An activated carbon filter must be fitted for this operating mode (see Filters and maintenance). The activated carbon filter can be purchased as an optional accessory FROM YOUR DEALER. The corresponding accessory numbers can be found at the end of these operating instructions. ❑ The extractor-hood fan extracts the kitchen vapours which are purified in the grease filter and activated carbon filter and then conveyed back into the kitchen. ❑ The grease filter absorbs the grease particles in the kitchen vapours. ❑ The activated carbon filter binds the odorous substances. If no activated carbon filter is installed, it is not possible to bind the odorous substances in the cooking vapours.
If the extractor hood is switched from exhaust-air mode to circulating-air mode, the exhaust-air opening must be sealed to prevent a hazardous situation (see optional accessories in the Instructions for use). Exhaust-air mode: ❑ The extractor-hood fan extracts the kitchen vapours and conveys them through the grease filter into the atmosphere. ❑ The grease filter absorbs the solid particles in the kitchen vapours. ❑ The kitchen is kept almost free of grease and odours. D If the extractor hood is operated in exhaust-air mode at the same time as a flue-type heater ( e.g.
gas, oil or solid-fuel heater, instantaneous water heater, boiler), ensure that there is an adequate air supply which the heater requires for combustion. Safe operation is possible provided that the partial vacuum in the room in which the heater is installed does not exceed 4 Pa (0.04 mbar). This can be achieved if the combustion air is able to flow through non-lockable openings, e.g. in doors, windows and in conjunction with an air supply/air-intake wall box or by other technical procedures such as reciprocal interlocking. 16 Heat shield (hinged to increase the suction area) Switch/light/ fan
