At maximum conditions data
Sound levels refer to units with nominal test
conditions.
The sound pressure level refers to a distance
of 1 meter from the outer surface of the unit
operating in open field.
Noise levels are determined using the tensiome-
tric method (UNI EN ISO 9614-2)
Data referred to the following conditions in
cooling:
- internal exchanger water = 12/7°C
- ambient temperature = 35°C
