Note
1. Data is valid at diffuse field condition.
2. Reference acoustic intensity 0dB = 10E-6μW/m
3. Sound power level is measured on the rated condition in the reverberation rooms. 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.
5. Sound level will vary depending on a range of factors such as the construction (acoustic absorption coefficient) of particular installed place in
which the equipment in installed.
6. Sound power level is measured in accordance with EN 12102-1 and ISO 9614.
• Rated : This mode is measured on the rated condition in the semi-anechoic rooms. Therefore, these values may vary depending on operation
conditions.
• Daytime max : This mode is measured based on max. fan RPM and max. compressor Hz. that can be reached under outdoor air temperature 2°C.
• Low noise : This mode lowers noise by limiting the compressor Hz. and fan RPM, and thus the performance may be limited.
