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
