[. . . ] Once the apparatus is hooked, fix it definitively to the wall using the two other screws and the holes made at its bottom (B). To avoid damage make exclusive use of the holes already prepared on the hood. Securing the telescopic flue: Basic installation requirements: ­ Set the electrical power supply within the space covered by the decorative flue. [. . . ] ­ If your unit is installed in an Exhaust hood, prepare the air exhaust hole. Place bracket (W) 50 mm from the ceiling and position this on the vertical of your hood, with the aid of the notches on the centre of the bracket (Fig. 6); using a pen, mark the 2 holes on the wall and then make the holes and fit the screw anchors provided and proceed to secure the bracket using the 2 screws (provided). Exhaust hoods: connect the disposal duct to the air evacuation pipe of the hood; use a flexible pipe and lock it to the air evacuation pipe of the hood with a metal hose clamp (pipe and clamp are not provided). Take 2 assembled flues and place these on the upper surface of the hood. Raise the upper flue as far as the ceiling and secure it to the bracket using the 2 screws (Fig. Filtering hood: make all power connections to the hood using the power cable. Fasten the air baffle to the lower flue as shown in Figure 8, using the 2 screws. 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). Button E: drives the motor in fourth 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). Pay special attention to the grease filters; to remove the filter: push inward on the clamp at the handle and pull the filter downward. If the model purchased has the controls shown in Figure 11/12: the grease filter must be cleaned periodically: exactly how often depends on use (at least once every other month). If the model purchased has the controls shown in Figure 14: the grease filters must be cleaned approximately once every 30 hours of operation (when the light button lamp comes on) - Fig. Once the cleaned filters are reinstalled, to reset the counter hold the light button pressed down for about 1" (Fig. Charcoal filter/s: if using the hood in the filtering hood, the charcoal filter must be replaced periodically. [. . . ] Charcoal filter/s: if using the hood in the filtering hood, the charcoal filter must be replaced periodically. To remove the charcoal filters, proceed as follows, depending on the model purchased: - if the hood features round charcoal filters (Fig. 10), remove the charcoal filter by first of all removing the two filter retainers M.
