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. Sound pressure levels are measured at 50Pa External Static Pressure condition.
7. 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.
