Acoustic data: Class 2 according to DIN EN ISO 3744, as third octave spectrum and octave spectrum.
Sound power measurement (MP2) of the Solflex acoustic enclosure with reference sound source inside the acoustic housing over a spherical envelope with 12 microphones.
Acoustic data: Class 2 according to DIN EN ISO 3744, as third octave spectrum and octave spectrum.

The difference between the two measurements is the sound level reduction of the acoustic housing.
* The measurement tolerance of +/- 1.5 dB(A) or tolerance range of 3 dB(A) according to DIN EN ISO 3744 was not taken in consideration and we publish only the minimum sound level reduction values.
Lowest pressure drop over the special acoustic grid with the same airflow direction of theinstalled outdoor unit.
