1. Specification
Note:
1. All data are based on the following conditions:
- Cooling Temperature : Indoor 26.7°C(80°F) DB / 19.4°C(66.9°F) WB
Outdoor 35°C(95°F) DB / 23.9°C(75°F) WB
- Heating Temperature : Indoor 21.1°C(70°F) DB / 15.6°C(60.1°F) WB
Outdoor 8.3°C(46.9°F) DB / 6.1°C(43°F) WB
- Piping Length : Interconnected Pipe Length = 5 m (16.4 ft)
- 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 ambi-
ent conditions during opration.
** : The unit could be operated on the followig temperature range only when Low
Ambient Kit installed.
- Cooling : Outdoor Temperature -20°C(-4°F) ~ -10°C(14°F) DB
