correct use in order to reduce the environmental impact:
Switch ON the hood at minimum speed when you start
cooking and kept it running for few minutes after cooking is
finished. Increase the speed only in case of large amount of
smoke and vapour and use boost speed(s) only in extreme
situations. Replace the charcoal filter(s) when necessary to
maintain a good odour reduction efficiency. Clean the grease

6
filter(s) when necessary to maintain a good grease filter
efficiency. Use the maximum diameter of the ducting system
indicated in this manual to optimize efficiency and minimize
noise.
Use
The hood is designed to be used either for exhausting or filter
version.
Ducting version
The hood is equipped with a top air outlet Bfor discharge of
fumes to the outside (exhaust pipe and pipe fixing clamps not
provided). 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.
Attention! If the hood is supplied with carbon filter, then it
must be removed.
Filter version
Should it not be possible to discharge cooking fumes and
vapour to the outside, the hood can be used in the filter
version, fitting an activated carbon filter and the deflector F
on the support (bracket) G, fumes and vapours are recycled
through the top grille Hby means of an exhaust pipe
connected to the top air outlet Band the connection ring
mounted on the deflector F(exhaust pipe and pipe fixing
clamps not provided).
Attention! If the hood is not supplied with carbon filter,
then it must be ordered and mounted.
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.
Mounting
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.
The electric connection box must be assembled as shown in
Fig. A-B-C.
Fig. 5
1. Drawing a line on the wall with a pencil up to the ceiling,
corresponding to the centre line, will make the installation
operations easier.
2. Apply the perforation diagram to the wall: the vertical
centre line printed on the perforation diagram should
correspond to the centre line drawn on the wall. In
addition, the lower edge of the perforation diagram
corresponds to the lower edge of the hood.
3. Make holes as indicated on the template, insert the wall
dowels and screw 2 screws into the upper holes, leaving
a space of about 1 cm between the head of the screw
and the wall.
Note: Always make the holes indicated on the template.
The upper 2 are for hooking the hood up while the lower
holes (generally 1 central or more lateral) are for the
definitive and safety fixing.
4. Apply flues support bracket „G“ to the wall touching the
ceiling. Use the flues support bracket as a perforation
diagram (the small slot in the support must coincide with
the line previously drawn on the wall, if present), and
mark two holes with a pencil. Make the holes and insert 2
dowels.
5. Fix the flues support bracket to the wall with 2 screws.
6. Hang the hood to the two upper screws (see installation

7
phase 3).
7. Introduce and screw the screws (and washer(s)) up into
the hole(s) for the definitive fixing (COMPULSORY!!).
Then, having checked the setting of the hood, TIGHTEN
ALL THE upper and lower SCREWS.
Note: the lower fixing points are visible removing the fats
filters and they are at the sides and/or at the centre of the
hood (after having removed the frame of the carbon filter,
if present, in the latter case).
In any case, we recommend using the lateral holes, when
available, to increase the stability of the hood.
8. Connect a tube (tube and bands for fixing not supplied, to
be purchased) for discharging the fumes to the
connection ring placed over the aspiration motor unit.
The other end of the tube should be connected to a
device for expelling fumes on the outside of the hood in
the aspiration version. If you want to use the filtering
version, fix deflector Fto flues support bracket Gand
connect the other end of the tube to the connection ring
placed on deflector F.
9. Connect the electricity.
10. Apply the flues and fix them above with 2 screws (10a) to
flues support bracket „G“ (10b).
11. Slide the lower section of the flue down to cover the
aspiration set until inserting it completely into the
apposite housing over the hood. Remount the carbon
filter frame and the fat/s filter/s and check the perfect
functioning of the hood.

Maintenance
ATTENTION! Before performing any maintenance operation,
isolate the hood from the electrical supply by switching off at
the connector and removing the connector fuse.
Or if the appliance has been connected through a plug and
socket, then the plug must be removed from the socket.
Cleaning
The cooker hood should be cleaned regularly (at least with the
same frequency with which you carry out maintenance of the
fat filters) internally and externally. Clean using the cloth
dampened with neutral liquid detergent. Do not use abrasive
products. DO NOT USE ALCOHOL!
WARNING: Failure to carry out the basic cleaning
recommendations of the cooker hood and replacement of the
filters may cause fire risks.
Therefore, we recommend observing these instructions.
The manufacturer declines all responsibility for any damage to
the motor or any fire damage linked to inappropriate
maintenance or failure to observe the above safety
recommendations.
Grease filter
Fig. 2
Traps cooking grease particles.
The grease filter must be cleaned once a month using non
aggressive detergents, either by hand or in the dishwasher,
which must be set to a low temperature and a short cycle.
When washed in a dishwasher, the grease filter may discolour
slightly, but this does not affect its filtering capacity.
To remove the grease filter, pull the spring release handle.
Charcoal filter (filter version only)
Fig. 3
It absorbs unpleasant odours caused by cooking.
The saturation of the charcoal filter occurs after more or less
prolonged use, depending on the type of cooking and the
regularity of cleaning of the grease filter.
In any case it is necessary to replace the cartridge at least
every four mounths.
The charcoal filter may NOT be washed or regenerated.
Remove the filter holder frame by turning the knobs (g) 90°
that affix the chimney to the cooker hood.
Insert the pad (i) of activated carbon into the frame (h) and fit
the whole back into its housing (j).
It is possible to use a traditional carbon filter, neither
washable nor regenerable, to be replaced every 3 - 4 months.
The filter holder frame of the carbon filter is welded together;
the eventual frame supplied with the hood is not, therefore, to
be used.
Insert it into its housing and fix it turning the 2 plastic knobs.
Replacing lamps
The hood is equipped with a lighting system based on LED
technology.
The LEDs guarantee an optimum lighting, a duration up to 10
times as long as the traditional lamps and allow to save 90%
electrical energy.
For replacement, contact the technical service.
