Notes:
1. Capacities and Inputs are based on the following conditions
Cooling : Indoor temp. 27°C [80.6°F]DB/19°C[66.2°F]WB
Water inlet temp. 30°C[86°F]
Heating : Indoor temp. 20°C[68°F]DB
Water Inlet temp. 20°C[68°F]
* Interconnecting Piping Length 7.5m (25 ft.)
* Level Difference of Zero
2. Capacities are net capacities.
3. Sound pressure level is measured on the rated condition in the anechoic
rooms by ISO 3745 standard.
4. Sound power level is measured on the rated condition in the reverbera-
tion rooms by ISO 3741 standard.
5. Wiring cable size must comply with the applicable local and national code.
6. Due to our policy of innovation some specifications may be changed
without prior notification.
7. Add an anti freeze to circulation water when outside units is operating
