Notes:
(1)  Performance  refers  to:  R410A 
refrigerant;  condensing  temperature 
45°C;  incoming  air  24°C-45%Rh; 
water 7/12°C; external static pressure 
30 Pa. The declared performance does 
not take into account the heat 
generated  by  fans,  which  must  be 
added to the system thermal load.
(2) EER (Energy Efficiency Ratio) = total 
cooling capacity / compressors power 
consumption  +  fans  power 
consumption  (air  cooled  condensers 
excluded).
(3) Sound levels at a 2 m distance, in a free 
field, as per UNI EN ISO 3744:2010.
