Sound levels refer to units at full load.
The sound pressure is measured at 1 m from the external surface of the ducted unit operating in an open field. (standard UNI EN ISO 9614-2)
Data referred to the following conditions:
- Internal exchanger water temperature = 12/7°C
- outdoor air temperature 35°C
- Static available pressure 120 Pa
Please note that when the unit is installed in conditions different from nominal test conditions (e.g. near walls or obstacles in general), the sound levels may undergo substantial variations.
