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, with working fans and compressor.
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 EER
refers only to the room unit. The unit air flow refers in standard configuration with clean class filter G3.
