Note:
1. All data are based on the following conditions:
- Cooling Temperature : Indoor 27°C(80.6°F) DB / 19°C(66.2°F) WB
Outdoor 35°C(95°F) DB / 24°C(75.2°F) WB
- Piping Length : Interconnected Pipe Length = 7.5m
2. Wiring cable size must comply with the applicable local and national code.
4. Sound Level Values are measured at Anechoic chamber.
Therefore, these values can be increased(maximum 3dB(A)) owing to ambient conditions during operation.
