1. General notes
The cooker hood needs a sufficient and correct supply of air to achieve an optimum
effect and maximum ventilation efficiency. If not enough fresh air is supplied, the
speed of the fan motor increases, the air throughput decreases and the noise level
rises.
When the filter mats are saturated, the air throughput of the cooker hood decreases
and the vapours are only cleaned to an inadequate extent.
Caution! When the hood is being installed, the distance between the lower edge of
the hood and the cooker must be at least 650 mm for gas cookers and at least
430 mm for electric cookers.
The cooker hoods EDIP 678.0 and EDIP 679.0 are intended for installation in a top
cupboard.

by hand or to select fully automatic operation, i.e. the cooker hood regulates the fan
setting automatically, depending on the cooking process involved.

3.2 Manual mode
When the button is pressed, the fans are activated at setting 3; this is indicated
on the LED display. By pressing the button again, setting 4 and the high-speed
setting can be selected; by activating the button, the fans can be turned down to
lower settings. The setting selected is shown in each case. The automatic display
does not come on.
3.3 Automatic mode
If the button is pressed once, the cooker hood is switched to automatic mode,
the A-lightcomes on. Fan setting 1 is the lowest setting and is always switched on. The
sensor probe checks the volume of steam and, when necessary, switches the fans
in increments up to the necessary setting. Thefan setting is regulated accordingly if
the steam volume changes.
FThe automatic function is only operable with the filter drawer pulled out.
3.4 Switching over between manual/automatic mode
When the button is activated, you can switch over from manual to automatic
modeandviceversa.
3.5 High-speed setting
At the high-speed setting the fans run with a greater air throughput.
It is switched on by pressing the button. The high-speed setting can be
switched off again by pressing the button or it switches itself off again
automatically after 10 minutes, i.e. ,
Fin manual mode to setting 3
Fin automatic mode to the setting determined by the sensor.
3.6 Intermittent ventilation
When intermittent ventilation is switched on, the fans run automatically after 55 minutes
at the lowest setting for about 5 minutes. This results in continuous ventilation of the
kitchen, e.g. also during the night. This is indicated by the light coming on.
FIntermittent ventilation only operates with the filter drawer pushed in.
FIntermittent ventilation can always remain activated.

3.7 Switching off
The appliance can be switched off in various ways:
1. Switching off without automatic delayed stop
Press button,
intermittent ventilation is also switched off.
2. Switching off with automatic delayed stop
Push filter drawer right in full. The fans continue to run for about another
10 minutes at the setting last selected.
To switch on again, the filter drawer must be pulled out again.
The intermittent ventilation remains switched on.
If the high-speed setting is to be switched on when the filter drawer is pushed in,
automatic reset takes place during the delayed-stop time.
Manual mode at setting 3.
Automatic mode to the required setting but at least to setting 1.
3.8 Lighting
The lighting can be used at any time even when the fans are switched off or the filter
drawer is pushed in.

Fat filter
FAn operating hour counter counts the operating time and after about
40 hours the LED comes on.
Charcoal filter
FAfter an operating period of 240 hours the LED comes on.

3.9 Ultrasonic control
This control has 3 elements consisting of:
–Operation section (in the filter pull-out drawer)
–Control section (above the air guide housing)
–Sensor (in the filter pull-out drawer)
In the case of repairs the control section and sensor are to be replaced together
as these two components are matched to each other.
An ultrasonic sensor measures the change in the air density. This change can be
caused by:
–rising sources of heat
–vapours formed by the cooking process
The cooker hood control adapts the fan speed to the cooking process in line with the
sensor pulses.
The ultrasonic frequency is 200 kHz; it is thus 10 times above the hearing range
of domestic animals.

3.10 Sensor sensitivity
The filter pull-out drawer accommodates a potentiometer to adjust the sensitivity of
the sensor.
It is supplied in the maximum setting (turned fully to right) as the optimum for electric
hobs. For operation above gas hobs, it is recommended to turn the potentiometer
back half a revolution (anticlockwise).
For complaints about automatic mode
–Control operates too slowly
–Activation in too high fan settings
the pulse number for the control can be adjusted. As a starting position, turn the
potentiometer clockwise right to the stop.
After dismantling the front filter, the adjustment feature is accessible.
If the cooking hood is switched on in this condition, the red LED flashes.
