CHAPTER 3. USE
The hood is designed to be used either for exhausting or filter version.
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.
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.
