All the performances (Cooling capacity, unit power input in cooling and EER) are based on the following conditions: evaporator 12.0/7.0°C; ambient
35.0°C, unit at full load operation; operating fluid: Water; fouling factor = 0.
(*)PHE: Plate Heat Exchanger; S&T: Single Pass Shell & Tube; MCH: Microchannel; DPT: Direct Propeller Type; DOL: Direct On Line - VFD: Inverter - BRS:
Brushless
(**) Sound power level (referred to evaporator 12/7°C, ambient 35°C full load operation) are measured in accordance with ISO 9614 and Eurovent 8/1
for Eurovent certified units. The certification refers only to the overall sound power level, the sound pressure is calculated from the sound power level and
are for information only and not considered binding. The minimum capacity indicated is referred to unit operating at standard Eurovent conditions.
Dimensions and weights are for indication only and not considered binding. Before designing the installation, consult the official drawings available from
the factory at request. All the data are referred to standard unit without options. All data are subject to change without notice.
(***) The value refers to the pressure drops in the evaporator only.
(****) In accordance with standard EN14825:2013, comfort low temperature, average climate. SEER and ηs values applicable Ecodesign regulation: (EU)
No 2016/2281.
