[. . . ] Fixing to the wall: Draw a line on the wall in vertical line with your hob. Mark the first 2 holes to be drilled in the wall, respecting the distances indicated in Fig. As already specified on the "Warnings" sheet, bear in mind that the distance between the lower edge of the hood and the hob must be min. [. . . ] Fix the metal bracket (A) to the wall using the 2 holes just drilled (Fig. Use the 2 cut-out triangles on the bracket to position it exactly along the vertical axis of the hood. Adjust the horizontal position moving the hood to the right or left so that it is aligned with the wall units. When adjustment has been completed, without removing the hood, mark the other 4 holes to be drilled (C) in the wall. Then use the 4 screw anchors and the 4 screws provided for final fixing. Fixing the telescopic flues: 4a - Adjust the width of the support bracket (D) of the telescopic flue by means of the screws (E) as shown in Fig. 8; then, by means of the screw anchors and screws (F) provided, fix the bracket to the ceiling in such a way that it is positioned along the axis with your hood. - Use a flexible pipe and lock it to the air vent of the hood with a metal hose clamp - Fig. - For exhaust hoods, turn the upper flue over so that the air exhaust grid is in the lower section (Fig. Starting the function Air Refresh, the hood recycles the air in the environment in perfect silence, starting every 5 minutes (for 10 minutes, at the first speed). NOTE: The Sensor and Air Refresh functions can be activated simultaneously by pressing the button P3 until both the icons (D4 and D7) come on. The icon switches on when the engine is at the first, second or third speed. To the fourth speed, the icon switches off and the icon starts working to the maximum speed (icon D3). It switches on when it is time to replace the charcoal filter/s (after about 120 working hours). One time the charcoal filter/ s is replaced, to make the hours calculation start again press the button P4. Sensor sensitivity: the sensor sensitivity can be modified by simultaneously pressing the buttons P3 and P4 (the value set appears on the display D5 and may be between 1 and 9). Warning: in order to avoid damaging the sensor, never use silicone products near the hood!Grease filters: the grease filter/s require particular care and must periodically be cleaned in relation to use.
