2.3 Operating principle
Fig. 4
Fig. 5
This extractor hood swiftly and silently extracts all odours produced while cooking. You can set
different intensity levels depending on the intensity of odours.
The fan in the extractor hood sucks in the kitchen vapours and passes them through the grease filter to outdoors. The grease filter absorbs the greasy components in the kitchen vapours (see Fig. 4).
The ???Coanda effect???
Kitchen vapours are extracted even better with the ???Coanda effect???. By means of an additional motor, kitchen vapours are passed swiftly and effectively into the hood???s extraction zone. An additional fan on the front edge of the kitchen extractor hood generates an air stream that is diverted around a cylinder towards the rear. This ensures that kitchen vapours are routed completely into the extractor hood???s filter area (see Fig. 5).

4. Cleaning and care
Caution!
Cleaning the grease filters:
The 
(Grease filter saturation) symbol flashes on the display after an operating time of 30 hours. Flashing of this symbol signals to you that the
grease filters have to be cleaned. The grease filters can be cleaned at any time, even if the 
(Grease filter saturation) symbol does not flash. The metal filters can be removed easily for cleaning.
Proceed as follows:
???Grip the grease filter handles and press the slide towards the rear.
???Pull the grease filter out of its mount in the downward direction (Fig. 12).
???Repeat the operation with the other grease filters.
You can clean the metal grease filters in a dishwasher at a maximum temperature of 65 ??C. Place the grease filters vertically in the dishwasher to ensure that no food remainders will stay on them.
Note:
The handles of the grease filters must be visible after installation. They can no longer be removed if the handles are in the inner part of the housing.
Slight discoloration can occur when cleaning the grease filters in a dishwasher.
When replacing the grease filters, wipe out the inner part of the housing with hot detergent solution.
Reinsert the grease filters in the hood after cleaning. Install them in the reverse order to removal.
Press the 
(Grease filter) key to set the elapsed hours counter to zero; the 
(Grease filter) symbol stops flashing.
Do not clean the appliance with a steam cleaning apparatus or with water pressure because this poses a risk of

Cleaning the glass plates
Apply commercially available window cleaning agent with a soft, moist cloth. To facilitate cleaning, you can detach the glass plates as follows:
Detach the grease filters. In the extractor hood, you will find two openings on the upper side through which you can lift the glass plates singly with a blunt object (e.g. handle of a wooden spoon) to detach them with greater ease.
If they are extremely soiled, the glass plates can be cleaned in a dishwasher at a maximum temperature of 55 ??C.
Cleaning the aluminium panel
Clean the aluminium panel with a soft cloth only. Do not use any strong or caustic cleaning agents or brushes and abrasive cleaner to clean it. Do not use strongly alkaline cleaning agents (such as oven spray) because these are aggressive to the aluminium surface. Do not use any abrasive sponges either.
Clean the stainless steel parts of the extractor hood (side panel, ventilation duct) with mild rinsing detergent and apply stainless steel care agent to the metal surfaces using a soft cloth.

6. Assembly instructions
6.1 Technical data
Weight: 41 kg without ventilation duct
Dimensions: 1198 x 560 mm
Electrical connection
Pay attention to the rating plate data.
The mains connecting cable must at least correspond to the type H 05
The appliance must only be connected by an authorised specialist, paying attention to the relevant regulations of the power supply companies and the regional construction regulations. He must explain to the user how the
appliance can be isolated from the mains whenever required.
The connector of the connecting cable is connec- ted to the socket that is located behind the duct cover on the wall. If this is not possible, it must be possible to isolate all poles of the appliance from the mains by way of the domestic fuse, or by means of accessible isolating device with a contact gap of at least 3 mm.
If the appliance is to be operated only with the window open (to ensure adequate incoming air), you can use the window switch.
A switch (normally open) is fitted on the window. On the appliance, this switch is connected to the window switch terminal on the main electronics. The appliance can now only be operated when the window is open.
Important: The window switch must only be connected by an authorised specialist.
Note: The light function works without restriction.
6.2 Installation
The applicable regulations of the energy supply companies and the regional construction regulations must be observed when installing the hood.
The minimum distance from the worktop to the bottom edge of the wall hood is for electrical appliances 650 mm and for gas appliances 750 mm.
The wall hood was conceived for the exhaust air mode. The exhaust air can be routed into a separate exhaust air shaft or directly into the open through the outside wall.
It is not allowed to pass the exhaust air into a flue or exhaust air chimney that is in operation or into a shaft that is linked to the heating basement. Consult the chimney sweep responsible for your district whenever you wish to pass the exhaust air into a chimney that is not in operation.
During the course of planning, a chimney sweep must be consulted if a room
Adequate incoming air must be ensured if a wood, coal, gas or oil heater or an open hearth is operated in the same room as the one in which the hood is installed.
Safe operation is possible whenever the partial vacuum in the place where the firing equipment is installed does not exceed 4 Pa (0.04 mbar).
This can be achieved whenever the air needed for combustion is able to enter through openings that cannot be sealed, for example in doors, windows, incoming/exhaust air wall boxes or other technical means.
