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
                   • 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
                   •  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. Wiring cable size must comply with the applicable local and national codes. And “Electric characteristics”
chapter should be considered for electrical work and design. Especially the power cable and circuit breaker
should be selected in accordance with that.
5. EEV: Electronic Expansion Valve
6. Anechoic chamber conversion value is measured at 1.5 m downward from unit centre. 
The values depends on the ambient conditions and values are normally higher in actual operation.
