Notes:
1. Capacities are based on the following conditions:
Cooling * Indoor temp. 27°C[80.6°F]DB/ 19°C[66.2°F]WB
* Outdoor temp. 35°C[95°F]DB/ 24°C[75.2°F]WB
* Interconnecting Piping Length 7.5m(24.6ft)
* Level Difference of Zero
Heating * Indoor temp. 20°C[68°F]DB/ 15°C[59°F]WB
* Outdoor temp. 7°C[44.6°F]DB/ 6°C[42.8°F]WB
* Interconnecting Piping Length 7.5m(24.6ft)
* Level Difference of Zero
2. Capacities are net capacities
3. Due to our policy of innovation some specifications may be changed without prior notification
