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 with an 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.
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.
