The boxy styling and stainless steel finish of the Siemens LC97BE532B chimney cooker hood brings industrial design to the domestic kitchen. This 90cm-wide hood offers a wall-mounted, relatively low-noise unit suitable for air extraction or recirculation. Extraction The hood has three-stage control plus boost setting. This highest extraction rate temporarily kicks in when kitchen vapour is especially intense. The system automatically reverts to normal settings after ten minutes of high-intensity operation. On this boost setting, the hood extracts air at a rate of 730m³/h, at 64dB. At the lowest of its three speeds, noise level is a mere 40dB. Lighting Energy-saving LED lighting illuminates the stove top. The hood has easily removable metal grease filters that can be cleaned in the dishwasher. Installation Installation of this hood must be carried out by a qualified engineer. It is designed for Wall mounting and the chimney section of the hood is supplied with a wall fixing system. Air circulation mode The hood can be converted to run in air-circulation mode, provided there is an adequate air intake through, for instance, an air-intake/exhaust-air wall box. There is a risk of poisoning from combustion gases if the air intake is inadequate. Air circulation operation also requires an activated carbon filter.
