(2) The sound pressure level is measured according to Standard EN-ISO 9614-1, and declared at the following
conditions:
•
in free field
•
with unit positioned on a reflective base
•
with unit running under nominal conditions.
The sound pressure level declared considers the contribution of the standard circulation pump.
