Note
1.Sound measured at 1.5m away from the center of the unit.
2.Operating condition
• Power source : 220-240V 50 Hz / 220V 60 Hz
• 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)
3.Reference acoustic intensity 0dB = 10E-6μW/m
4.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.
