Any frying must be done with care in order to make sure that the oil does not overheat and ignite. [. . . ] Suggestions for a correct use in order to reduce the environmental impact: Switch ON the hood at minimum speed when you start cooking and kept it running for few minutes after cooking is finished. Increase the speed only in case of large amount of smoke and vapour and use boost speed(s) only in extreme situations. Replace the charcoal filter(s) when necessary to maintain a good odour reduction efficiency. Clean the grease 14 filter(s) when necessary to maintain a good grease filter efficiency. Use the maximum diameter of the ducting system indicated in this manual to optimize efficiency and minimize noise. Additional Installation Specifications: Use only the fixing screws supplied with the product for installation or, if not supplied, purchase the correct screws type. Use the correct length for the screws which are identified in the Installation Guide. In case of doubt, consult an authorised service assistance centre or similar qualified person. Failure to install the screws or fixing device in accordance with these instructions may result in electrical hazards. Installation The minimum distance between the supporting surface for the cooking equipment on the hob and the lowest part of the range hood must be not less than 50cm from electric cookers and 65cm from gas or mixed cookers. If the instructions for installation for the gas hob specify a greater distance, this must be adhered to. Electrical connection The mains power supply must correspond to the rating indicated on the plate situated inside the hood. If provided with a plug connect the hood to a socket in compliance with current regulations and positioned in an accessible area, after installation. If it not fitted with a plug (direct mains connection) or if the plug is not located in an accessible area, after installation, apply a double pole switch in accordance with standards which assures the complete disconnection of the mains under conditions relating to over-current category III, in accordance with installation instructions. Before re-connecting the hood circuit to the mains supply and checking the efficient function, always check that the mains cable is correctly assembled. The hood is provided with a special power cable ; if the cable is damaged, request a new one from Technical Service. Use The hood is designed to be used either for exhausting or filter version. Ducting version In this case the fumes are conveyed outside of the building by means of a special pipe connected with the connection ring located on top of the hood. Diameter of the exhausting pipe must be equal to that of the connection ring. In the horizontal runs the exhausting pipe must be slightly slanted (about 10°) and directed upwards to vent the air easily from the room to the outside. If the hood is supplied with active charcoal filter, then it must be removed. Connect the hood and discharge holes on the walls with a diameter equivalent to the air outlet (connection flange). Using the tubes and discharge holes on walls with smaller dimensions will cause a diminution of the suction performance and a drastic increase in noise. Use a duct with as few elbows as possible (maximum elbow angle: 90°). [. . . ] To switch off the system, re-press the same two buttons: after 3 seconds LED 5 will stop flashing and the device will be switched off. Intensive speed LED Intensive speed ON switch This speed should be used when the concentration of cooking fumes or odours is particularly strong (for example when frying, cooking fish etc. ). When washed in a dishwasher, the grease filter may discolour slightly, but this does not affect its filtering capacity. To remove the grease filter, pull the spring release handle.
