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
4. To be added for more available Models
5. EEV : Electronic Expansion Valve
6. Noise Level is Standard Mode
(for actual High Mode(factory set) condition, Noise Level may exceed the standard level by 1.5dBA)
Conversion Formula
kcal/h= kW x 860
Btu/h = kW x 3412
