[. . . ] Once regulation has been completed, finish securing the hood with 4 more screws (M): mark the points for the 4 holes on the wall, remove the hood and drill (8mm diameter holes); then use the plugs and screws to complete installation. Rest the lower edge of the panel behind the stove and anchor the upper edge to the wall using the two holes found on the panel. [. . . ] Button B = turns the TIMER on/off: press once to turn the timer on, therefore, after 5 minutes, the motor cuts out (at the same time the selected speed blinks on the display); the timer remains on if the motor speed is changed. Display C = - indicates the selected motor speed (from 1 to 4); - indicates Timer On when the number blinks; - indicates Filter Alarm when the central segments is on or blinking. Button D = makes the motor work (at the last speed selected); pushing the button again, the speeds of the motor are sequentially selected from 1 to 4; keeping this button pressed for about 2 seconds shuts down the motor. When the central segment on the display goes on), the anti-grease filters must be cleaned (30 hours of operation); when the central segment starts Blinking, the anti-grease filters must be cleaned and the charcoal filters replaced (120 hours of operation). Obviously, if the hood is not a filtering model and does not have a charcoal filter , clean the anti-grease filters both when the central segment goes on and when it starts blinking. The filter alarm can be seen when the motor is off and for about 30 seconds. To reset the hour counter, keep the button pressed for 2 seconds while the alarm can be seen. 18: Button A: turns the lights on/off; every 30 hours of operation the corresponding pilot lamp (S) comes on to indicate that the anti-grease filters must be cleaned; every 120 hours of operation the corresponding pilot lamp (S) flashes to indicate that the anti-grease filters must be cleaned and the charcoal filter replaced. To restart the hour counter (RESET), hold the button A pressed down for about 1" (while the pilot lamp S is on). Button B: drives the motor in first speed (the corresponding pilot lamp comes on); when pressing the button a second time (while the pilot lamp is on), the TIMER is activated and thus the motor stops after 5' (the pilot lamp flashes); when holding it down for about 1", the motor cuts out. Button C: drives the motor in second speed (the corresponding pilot lamp comes on); when pressing the button a second time (while the pilot lamp is on) , the TIMER is activated and thus the motor stops after 5' (the pilot lamp flashes). Button D: drives the motor in third speed (the corresponding pilot lamp comes on); when pressing the button a second time (while the pilot lamp is on) , the TIMER is activated and thus the motor stops after 5' (the pilot lamp flashes). [. . . ] If the model purchased has the commands shown in Figure 17, the charcoal filters must be replaced according to use: on average once every 6 months. If the model purchased has the commands shown in Figure 18, the charcoal filters must be replaced each time the light button (Fig. [. . . ]
