Notes:
1. Sound measured at 1.5m away from the center of the unit
2. 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)
3. Reference accoustic pressure 0dB = 20μPa
4. Sound level will vary depending on a range of factors such
as the construction(acoustic absorption coefficient) of par-
ticular room in which the equipment in installed.
