1. Safety
Danger!
Repairs may only be carried out by a qualified electrician!
Improper repairs can be extremely dangerous for the user.
It is essential that you observe the following instructions in order to prevent electric shocks:
• The casing and the frame may be live in the event of faults!
• 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 repair work!
• When inspecting live parts, a residual current circuit breaker must always be used!
• The earthed conductor resistance must not exceed the resistance specified in the standard! It is vital
for ensuring the safety of persons 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 in accordance with the corresponding regulations for
your country!
Make sure you observe the following instructions:
• The appliances must be disconnected from the mains prior to all repairs. If inspections must be
carried out on live appliances, make sure you use a residual current operated device.
Attention!
Sharp edges: Use protective gloves.
Components may be electrostatic!
Observe handling precautions

2. General Information
A clearance of at least 30 cm must be maintained between the pan support area on the hob and the
bottom of the cooker hood. If the instructions for installation of the hob specify a larger clearance, this is
to be maintained.
The exhaust air ducts may not be connected to combustion exhaust gas chimneys (for example central
heaters, heaters, bathroom heaters, etc.).
Official regulations for discharging the exhaust air must always be observed. Furthermore, the exhaust
air may only be lead through a hole in the wall if the hole is intended for this purpose.
Attention! Care must be taken when an extraction
cooker hood and a heating system operating on
ambient air (e.g. gas, oil or coal heaters, flow
heaters or hot water boilers) since extracting the air
through the cooker hood will remove the air from
the room in which these heaters are installed and
which they need for combustion purposes.
Operation will only be safe if, in the case of
simultaneous operation of a hood and a heater
requiring ambient air, negative pressure in the
room in which the heater and the hood are installed
does not exceed 0.04 mbar, thus ensuring that the
exhaust gases of the heaters will not be re-
absorbed. The room must be fitted with ventilation
connections which ensure a constant inflow of fresh
air.
ATTENTION: This appliance must be earthed.
Make sure that the socket of electrical connections is earthed. In the case of electrical connection a
check will need to be carried out to ensure that the voltage level of the mains power supply complies with
the voltage levels indicated on the nameplate located on the inside of the appliance. If your hood has not
been fitted with a permanently connected cable with a plug or another device to enable universal
disconnection with a contact opening of at least 3 mm, suitable cut-off devices will need to be provided
for permanent connection. When installing the hood make sure that the plug is accessible if your hood
is fitted with a mains supply cable with a plug.
The hood must be disconnected from the mains power supply before it is cleaned or before any
maintenance work is carried out.
ATTENTION: DO NOT USE ANY PRODUCTS CONTAINING SILICONE NEAR THE COOKER HOOD,
SINCE THIS MAY DAMAGE THE SENSOR!

5. Buttons and functions
The extractor hood is equipped with a fully automatic system for administrating all of the available
functions (Advanced Sensor Control). The air in the kitchen stays pleasant and fresh without requiring
any manual controls. The sensitive sensors detect any type of steam, vapours, odours and GAS and
automatically adjust the hood to the required fan power.

5.2 Functions
Filter alarm
Is shown for 30 sec. when the motor is switched off. After an operation period of 30 hours the middle
segment on the display will light up to indicate that the anti-grease filter needs to be cleaned. After
an operation period of 120 hours the middle segment on the display will blink to indicate that the
grease filter needs to be cleaned and that the charcoal filter needs to be replaced.
After the grease filter has been cleaned (and/or the charcoal filter has been replaced), button C
(RESET) needs to be pressed while the filter alarm is being indicated in order to reset the hour
metre.
Sensitivity of the gas sensor
The sensitivity of the gas sensor may be adjusted to suit the personal needs of a user.
To adjust the sensitivity, the appliance must be in the manual operation status (i.e. the letter A is
not shown on the display, instead the current speed is shown).
Button Emay need to be pressed.
The degree of sensitivity can be adjusted by pressing buttons Dand Esimultaneously. The display
shows the level of sensitivity which has been set (from level 1 = lowest sensitivity to level 9 = highest
sensitivity).
Use buttons C(-) and D(+) to set the required level of sensitivity.
Pressing button Ewill store the “new” sensitivity setting.
