Overall
Note
1.Data is valid at free field condition.
2.Reference accoustic pressure 0dB = 20
μ Pa.
3.Data is valid at nominal operation condition.
Refer to the Model Specifications for nominal
conditions(Power source and Ambient temperature, etc)
4.Sound levels can be increased in accordance with
installation and operating conditions. (Operating conditions
include some functional condition like Static pressure
mode, air guide use, Room target temperature setting, etc
and these functions are different in accordance with each
model.)
5.Sound level will vary depending on a range of factors such
as the construction(acoustic absorption coefficient) of
particular room in which the equipment in installed.
