  Cooling capacities are based on outdoor air temperature of 35°C Dry Bulb with controlled indoor water inlet 

temperature of 12°C and water outlet temperature of 7°C. 

  Heating capacities are based on outdoor air temperature of 7°C Dry Bulb (44.6°F Dry Bulb), 6°C Wet Bulb 

(42.8°F Wet Bulb) with controlled indoor water inlet temperature of 30°C and water outlet temperature of 35°C. 

  Specification are subjected to change without prior notice for further improvement. 
  Flow rate indicated are based on nominal capacity adjustment of leaving water temperature (LWT) 35°C and 

∆
