Connecting to the power network and operation check
After connecting the device to the power supply network (in accordance with the requirements defined above) it is
necessary to check operation of the motor and lighting of the hood.
Setting the operation mode of the kitchen extractor hood
Setting the air extractor mode of operation of the hood
In the extractor mode air is discharged to the outside by a special conduit. In that setting any carbon filters shall be
removed. The hood should be connected to the opening discharging air to the outside by means of a rigid or flexible
conduit of 120 mm diameter, which should be purchased in a shop selling installation materials.
A qualified installer should be commissioned to make the connection.
Setting the odour absorber mode of operation of the hood
In this option filtered air returns to the room through openings in the front of the hood.
In this setting it is necessary to install the carbon filter
Fan speeds
The lowest and medium speeds should be used under normal conditions and with low concentration of fumes. The
top speed should be used in case of high concentration of kitchen fumes, e.g. during frying or grilling.

Please refer to mounting template enclosed with the appliance (fig. 3a)
Wall plugs
Using a hammer drive the Ø10 mm wall plugs into the wholes (A,B,C,D) for the fixing screws. For the
duct, use 2x6 mm wall plugs in the Ø4 mm holes (fig. 3b).
Screw the hanging screws
Screw the 5,5x45 hanging screws in the Ø8 wall plugs (A,B) that are already driven in the wall. The
screws should protrude from the wall about 5 mm (fig. 3c).
Install the hood
This model is not available with hanging plate. Hang your product on the slot on the back and then fix
it with the screws (fig. 3d and 3e).
Install the aluminium duct
Connect aluminium flexible duct to outlets on the product and kitchen wall. Ensure connection will hold
when the product is operated at airflow level (fig. 3f and 3i).
Install enclosures.
To install the enclosure use 3,9x x 9,5 flat head RYSB screws (fig. 3g and 3h).
a) Lower duct enclosure
b) Upper duct enclosure
Bending the aluminium duct reduces the air flow, so makes sure there are as few bends as possible
(fig. 4).
