Sound levels refer to full load units, in test nominal conditions. The sound pressure level refers to 1 m. from the standard unit outer surface operating in open field. Measures accor-
ding to UNI EN ISO 9614-2 regulations, with respect to the EUROVENT 8/1 certification, which provides for a tolerance of 3 dB(A).
Data referred to the following conditions:
- internal exchanger water temperature = 12/7 °C
- ambient temperature = 35 °C
