1. Safety
Danger!
Repairs may only be carried out by a qualified electrician! Repairs carried out
improperly may put the user at risk.
To prevent electric shocks, please observe the following:
• In the event of faults, the housing and the frame may be live.
• Touching live components inside the appliance may cause dangerous currents to flow through your
body.
• Disconnect the appliance from the mains prior to carrying out any repairs.
• When inspecting live parts, a residual current operated device must be used at all times.
• The ground wire resistance must not exceed that specified in the standard. It is of vital importance
for ensuring the safety of people and the functioning of the appliance.
• On completion of repairs, an inspection must be carried out in accordance with VDE 0701
[Association of German Electrical Engineers] or the corresponding regulations for your country.
Caution!
Make sure you observe the following instructions:
• The appliances must be disconnected from the mains prior to carrying out any repairs. If inspections
must be carried out on live appliances, make sure you use a residual current operated device.
Sharp edges: Use protective gloves.
Components may be electrostatic!
Observe handling precautions!

2. General Information
Altering the specifications or attempting to modify the product is dangerous. For your own safety, have
spare parts installed by a professional electrician. The manufacturer is not liable for any damage
resulting from improper installation or the non-observance of current regulations for this type of
application. Please read through the installation instructions carefully prior to commencing with work.
In order to be able to achieve an optimal effect and the best possible ventilation, the cooker hood needs
sufficient inlet air which has been properly supplied. In the event of an insufficient supply of inlet air, the
number of revolutions of the ventialtion motor will rise, the ventilation power will be reduced and the
appliance will be noisier.
Should the filter mats become saturated, the ventilation power of the cooker hood will be reduced and
vapours will be insufficiently removed.
The cooker hood has been designed to draw off steam resulting from cooking and is supplied with an
exhaust air operating mode. Should it not be possible to draw off the air to the outside, respective
optional accessories may be used to adapt the hood for the recirculation air mode with charcoal filters.
On installing the hood, the following points are to be observed in addition to currently-valid safety
instructions and the respective instructions of your country:
1. The cooker hood must always be installed above the centre of the hob.
2. The clearance stipulated for instalment must be maintained.
The minimum distance between hobs and the lower edge of the hood must be 650 mm.
The minimum distance between gas hobs and the lower edge of the hood must be 700 mm.
3. Exhaust air may not be discharged into a smoke chimney, exhaust gas chimney or into a shaft for
ventilating rooms where hearths or fireplaces have been installed. Should exhaust air be
discharged into smoke chimneys or exhaust gas chimneys which are not in operation, prior
approval must have been granted by the master chimney sweep responsible.
4. In the case of exhaust air operation of the extractor hood and the simultaneous operation of
heating systems requiring a chimney (such as gas, oil or coal heaters, flow heaters or hot water
boilers), a sufficient supply of inlet air, required by the fireplace for combustion purposes, must be
ensured. The negative pressure in the location of the fireplace may not exceed 4 PA (0.04mbar).
This is achieved if it is possible for more air to flow in. In order to assess this, the entire ventilation
system of a house or appartment must always be taken into consideration.
In the case of the recirculating air mode, the cooker hood can be operated without any restric-
tions.
5. The cooker hood may only be installed above a fireplace for solid fuels where there may be a risk
of fire (e.g. flying sparks) if the fireplace has a fully enclosed, permanent cover.

3. Functional characteristics
Both cooker hoods have the following features:
• Programmable exhaust air or recirculating air operation
• Automatic switch-off for the duration of the high-power setting
• Automatic switch-off for the follow-on time of the fan
• Grease filter saturation indicator
• Charcoal filter saturation indicator
• Remote control (optional accessory)
3.1 Control panel
There is a choice of four power settings. The required power level is set with the LEDs 1, 2, 3 and Max.
1 = low motor speed
2 = medium motor speed
3 = high motor speed
Max. = high-power setting
When the fan is switched on by means of pressing the respective LED, namely 1, 2 or 3, the correspond-
ing LED will light up orange. Press the active LED (lights up orange) once again in order to switch off
the fan.
The high-power setting is generally only needed for a short time. For this reason the cooker hood will
switch down to level 3 after 10 minutes.
When the high-power setting has been activated the “Max“ LED will light up orange.
In order to switch the lamp on and off press the lamp led.
3.2 Automatic switch-off for the period in which the high-power
setting is in operation
In order to achieve maximum extraction, it is recommended that a specific period of operation be
programmed for the high-power setting prior to commencing with cooking. This period can be limited by
means of a time function element. Program the automatic switch-off device for the period of operation
of the high-power setting as follows:
1. Switch on the motor (LED 2), then select the required setting for cooking with the (+) and (-)
LEDs.

2. The high-power setting is activated by means of pressing LED 5 (Max.) once. The fan is automati-
cally switched back to the previously-set power level when the “5 minutes follow-up time“of the
high-power setting has elapsed.
3. The high-power setting is switched off by means of activating LED 5 (Max.) once again.
Attention: This function cannot be carried out if the “automatic switch-off for the follow-up
time of the fan“has been activated.
3.3 Automatic switch-off device for the fan follow-up time
This function enables any remaining cooking steam to be extracted by means of time-limited extraction
(follow-up time) subsequent to the actual cooking process, after which the fan and the lamps are
switched off automatically.
The lamp and the motor must be switched off at the controls in order to program this function. The cooker
hood, however, must be connected to the mains. Pressing switch no. 5 (INT) once or several times will
adjust the follow-up time as follows:
• 1 blink of the LEDs 1 and 5 indicates the "Off" function.
• 2 blinks of the LEDs 1 and 5 indicate "5 minutes follow-up time".
• 3 blinks of the LEDs 1 and 5 indicate "10 minutes follow-up time".
• 4 blinks of the LEDs 1 and 5 indicate "15 minutes follow-up time".
Please switch on the appliance once it has been progammed. Set the required fan power level. The
follow-up time programmed will be indicated by the blinking of LEDs 2, 3 and 4 as follows:
In the case of the MAX. setting
• LEDs 2, 3 and 4 do not blink if the "automatic switch-off " function has not been activated.
• LEDs 2, 3 and 4 blink once if a follow-up time of "5 minutes" has been programmed.
• LEDs 2, 3 and 4 blink twice if a follow-up time of "10 minutes" has been programmed.
• LEDs 2, 3 and 4 blink three times if a follow-up time of "15 minutes" has been programmed.
In the case of the MED. setting
• LEDs 2, 3 and 4 do not blink if the "automatic switch-off” function has not been activated.
• LEDs 2 and 3 blink once if a follow-up time of "5 minutes" has been programmed.
• LEDs 2 and 3 blink twice if a follow-up time of "10 minutes" has been programmed.
• LEDs 2 and 3 blink three times if a follow-up time of "15 minutes" has been programmed.
In the case of the MIN. setting
• LEDs 2, 3 and 4 do not blink if the "automatic switch-off” function has not been activated.
• LED 2 blinks once if a follow-up time of "5 minutes" has been programmed.
• LED 2 blinks twice if a follow-up time of "10 minutes" has been programmed.
• LED 2 blinks three times if a follow-up time of "15 minutes" has been programmed.
