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 eld. Measures according to UNI EN ISO 9614-2 regulations, with respect to
the EUROVENT 8/1 certication. Data referred to the following conditions.
- internal exchanger water = 12/7 °C
- ambient temperature = 35 °C
