ELECTRIC CONNECTION

HOW TO USE THE APPLIANCE

The mains voltage shall be the same as the 

voltage shown on the rating label found  inside 

the hood. If  the hood is equipped with a plug, 

connect the hood to a socket compliant with 

current regulations,  which can be  easily rea-

chable  even after installation. If the hood is not 

equipped with a plug (direct connection to the 

mains) or the plug is not located in an easily 

accessible area, even after installation, use a  

standard- compliant two-pole switch that en-

sures   complete disconnection from the mains 

under overvoltage category III  , in accordance 

with current  installation rules and norms.

CAUTION!

Before reconnecting the hood circuit to power 

supply  and verifying proper operation, always 

check that the mains lead/cable has been fitted 

correctly. The hood is equipped with a special 

power cord; if the cord is damaged, send a 

request to the technical service department.

Tips for the hood proper correct use aimed 

at reducing environmental impact:

Turn on the hood at minimum speed when 

you start cooking , and leave it on for a few 

minutes even after cooking has been com-

pleted . Increase the speed only in the case 

of large amounts of fumes  and vapors, using 

the booster function only when absolutely 

necessary. To keep the odor reduction system 

efficient, replace the charcoal filter(s) as nee

-

ded. To keep the grease filter efficient , clean it 

when  necessary. Use a ducting system of the 

maximum diameter indicated in this manual, 

in order to  optimize efficiency and minimize 

noise. The hood has been designed to be used 

either  in the extraction mode with air dischar-

ged outside the room,  or in the recycling mode 

with air internal recirculation

EXTRACTION MODE

Vapors are discharged  to the outside through 

an exhaust pipe fixed to the connecting flange.

CAUTION!

The exhaust  pipe is generally not supplied 

with the appliance and must be purchased 

separately. The exhaust  pipe diameter should 

ideally be the same as the diameter of the 

connecting ring (connecting flange) (Ø150/ 

Ø120 - page 3).

CAUTION!

If the hood is equipped with charcoal filter(s), 

they must be removed in the case the hood is 

operated in the extraction  mode .

Connect the hood to pipes and wall outlets 

having the same diameter as the air outlet 

(connecting flange). The use of pipes and wall 

outlets with a smaller diameter will result in a 

decrease in extraction performance and a high  

increase in noise level . We therefore decline 

all liability in this regard.

Use a pipe  of the necessary length.  In hori-

zontal sections, the pipe should have a slight 

slope (approx. 10%) to better convey the air to 

the outside of the room.

- Use a duct with as few bends as possible 

(maximum bend angle: ≤90°).

- Avoid abrupt changes in duct cross-section.

Only for Germany: When the cooker hood 

and appliances powered by energy other than 

electricity are operating simultaneously, the 

negative pressure in the room shall not exceed 

4 Pa (4 x 10-5 bar).

RECYCLING MODE

The air extracted is ‘degreased’ and ‘deodo-

rized’ before being conveyed back into the 

room. To use the hood in this mode, you need  

to fit  an additional filtering system based 

on charcoal filters, in case your hood is not 

already equipped with it, by simply following 

the instructions given  in the recirculating  kit 

(page 3).
