Filter Saturation Indicator; Correct Ventilation; Important To Know - AEG 8490 D Operating And Installation Instructions

Delayed switch off
The delayed switch off can be activated with knob T6 while the motor is
running
The display shows remaining minutes until the motor and lamps (if on)
are switched off
The switch off delay is depending on motor speed:
Speed 1: 20 minutes
Speed 2: 15 minutes
Speed 3: 10 minutes
Intensive speed: 5 minutes

Filter saturation indicator:

If the display shows the letter "F", it means that the grease filters should
be cleaned (after running 40 hours)
If the display shows the letter "C", it means that also the carbon filter
should be cleaned or replaced (after running 160 hours). See
Maintenance.
To reactivate the filter saturation indication and erase the letters F or C
from the display, press when in OFF mode the knobs T4 and T5
simultaneously for minimum 2 seconds.
The saturation indicator is reset when "F" or "C" turn off on the display.
Caution: the appliance is not set to indicate saturation of the charcoal
filter. If you decide to use it in recirculation mode (with charcoal filter)
signalling of filter saturation must be set as follows: turn the hood OFF,
then press T5 and T6 simultaneously for 3 seconds.

Correct ventilation

If the cooker hood is to work correctly there must be an
underpressure in the kitchen. It is important to keep the kitchen windows
closed and have a window in an adjacent room open.

Important to know

Not applicable for recirculation. Great care must be taken if the hood is
used at the same time as a burner or fireplace (e.g. gas, diesel, coal or
wood heaters, water heaters, etc.), as the hood will expel air which is
required by these other appliances. Attend to it by opening a window. The
negative pressure in the room must not exceed 0,04 mbar to prevent fumes
being drawn back into the room by the cooker hood.
