7. Sound levels
7.2 Sound power level
Notes:
1. Operating condition
- Power source : 220-240V 50Hz / 220V 60Hz
- Cooling : Indoor temperature (27°C DB, 19°C WB), Outdoor temperature (35°C DB, 24°C WB)
- Heating : Indoor temperature (20°C DB, 15°C WB), Outdoor temperature (7°C DB, 6°C WB)
- External static pressure is according to "Standard mode" value. Refer the specifications.
2. Reference acoustic intensity 0dB = 10E-6μW/m
3. 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.
