Note
1. 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)
• External static pressure is according to “Standard mode” value. Refer the specifications.
2. Reference acoustic intensity 0dB = 10E-6μW/m
