1. Specification

Note:

1. All data are based on the following conditions:

- Cooling Temperature : Indoor 26.7℃(80℉) DB / 19.4℃(67℉) WB

Outdoor 35℃(95℉) DB / 23.9℃(75℉) WB

- Heating Temperature : Indoor 21.1℃(70℉) DB / 15.6℃(60℉) WB

Outdoor 8.33℃(47℉) DB / 6.11℃(43℉) WB

- Piping Length : Interconnected Pipe Length = 7.5m

- Difference Limit of Elevation (Outdoor ~ Indoor Unit) is Zero.

2. Wiring cable size must comply with the applicable local and national code.

3. Due to our policy of innovation some specifications may be changed without notification.

4. Sound Level Values are measured at Anechoic chamber.

Therefore, these values can be increased(maximum 3dB(A)) owing to ambient conditions during operation.
