1 ON THE FOLLOWING STANDARD CONDITIONS:
standard supply [voltage  10%]; room conditions 24°C bs; 50% R.H. (17°C bu)
2 Measured in the front part at 1 m height, 2 m distance, referred to free field.
ATTENTION: the refrigerating outputs are meant after deduction of the heat taken from the fans, which must thus be added to the room load. The
unit air flow refers to high speed, in standard configuration with clean class filter G3.
