Sound levels refer to the unit at full load installed on the ceiling,
ducted, with nominal fan air flow rate. Available static pressure 40
Pa.
In accordance with the UNI-EN ISO 3744 regulation, the average
sound pressure level refers to a distance of 1 m from the external
surface of the unit in open field conditions.
The power measurements are taken in accordance with the UNI
EN ISO 9614-2 standard, with a ducted unit installed near a
reflective surface
If the unit is installed in conditions other than the nominal ones
(for instance, near walls or obstacles in generally) the sound
levels may undergo substantial variations.
The limits are meant as an indication.
Please note that they have been
calculated by considering:
-
general and not specific sises,
-
clean batteries and filters,
-
non-critical positioning of the unit
and correct operating and
maintenance of the unit.
