Use

The hood is designed to be used either for exhausting or filter 
version. 

 Ducting version

In this case the fumes are conveyed outside of the building by 
means of a special pipe connected with the connection ring 
located on top of the hood. 

Attention

! The exhausting pipe is not supplied and must be 

purchased apart. 
Diameter of the exhausting pipe must be equal to that of the 
connection ring. 
In the horizontal runs the exhausting pipe must be slightly 
slanted (about 10°) and directed upwards to vent the air easily 
from the room to the outside. 
Attention! If the hood is supplied with active charcoal filter, 
then it must be removed. 

Connect the hood and discharge holes on the walls with a 
diameter equivalent to the air outlet (connection flange). 
Using the tubes and discharge holes on walls with smaller 
dimensions will cause a diminution of the suction performance 
and a drastic increase in noise. 

Any responsibility in the matter is therefore declined.  

!

Use a duct of the minimum indispensible length. 

!

Use a duct with as few elbows as possible (maximum 
elbow angle: 90°). 

!

Avoid drastic changes in the duct cross-section. 

!

Use a duct as smooth as possible inside. 

!

The duct must be made of certified material. 

 Filter version

One active charcoal filter is needed for this and can be 
obtained from your usual retailer.  
The filter removes the grease and smells from the extracted 
air before sending it back into the room through the upper 
outlet grid. 

The models with no suction motor only operate in ducting 
mode, and must be connected to an external suction device 
(not supplied). 
The connecting instructions are supplied with the peripheral 
suction unit.  

Installation 

The minimum distance between the supporting surface for the 
cooking equipment on the hob and the lowest part of the 
range hood must be not less than 50cm from electric cookers 
and 65cm from gas or mixed cookers. 
If the instructions for installation for the gas hob specify a 
greater distance, this must be adhered to. 

  Electrical connection 

The mains power supply must correspond to the rating 
indicated on the plate situated inside the hood. If provided with 
a plug connect the hood to a socket in compliance with current 
regulations and positioned in an accessible area, after 
installation. If it not fitted with a plug (direct mains connection) 
or if the plug is not located in an accessible area, after 
installation,  apply a double pole switch in accordance with 
standards which assures the complete disconnection of the 
mains under conditions relating to over-current category III, in 
accordance with installation instructions. 

Warning!

 Before re-connecting the hood circuit to the mains 

supply and checking the efficient function, always check that 
the mains cable is correctly assembled. 
The hood is provided with a special power cable ; if the cable 
is damaged, request a new one from Technical Service. 

Mounting

This type of cooker hood must be fixed to the ceiling. 

Very heavy product; hood handling and installation must 
be carried out by at least two persons. 

Before beginning installation: 

• 

Check that the product purchased is of a suitable size for 
the chosen installation area. 

• 

Remove the charcoal (*) filter/s if supplied (see also 
relative paragraph). This/these is/are to be mounted only 
if you want lo use the hood in the filtering version. 

• 

Check (for transport reasons) that there is no other 
supplied material inside the hood (e.g. packets with 
screws (*), guarantees (*), etc.), eventually removing 
them and keeping them. 

• 

If possible, disconnect and move freestanding or slide-in 
range from cabinet opening to provide easier access to 
rear wall/ceiling. Otherwise put a thick, protective 
covering over countertop, cooktop or range to protect 
from damage and debris. Select a flat surface for 
assembling the unit. Cover that surface with a protective 
covering and place all canopy hood parts and hardware 
in it. 

• 

In addition check whether near the installation area of the 
hood (in the area accessible also with the hood mounted) 
an electric socket is available and it is possible to 
connect a fumes discharge device to the outside (only 
suction version).  

•  Carry out all the masonry work necessary (e.g. 

installation of an electric socket and/or a hole for the 
passage of the discharge tube). 

Expansion wall plugs are provided to secure the hood to most 
types of walls/ceilings. However, a qualified technician must 
verify suitability of the materials in accordance with the type of 
wall/ceiling. The wall/ceiling must be strong enough to take 
the weight of the hood. 

Do not tile, grout or silicone this 

appliance to the wall. Surface mounting only.
