1.  Cooling capacities are based on indoor temperature of 27°C Dry Bulb (80.6°F Dry Bulb), 19.0°C Wet Bulb (66.2°F Wet Bulb) and outdoor air 
temperature of 35°C Dry Bulb (95°F Dry Bulb), 24°C Wet Bulb (75.2°F Wet Bulb) 
2.  Heating capacities are based on indoor temperature of 20°C Dry Bulb (68°F Dry Bulb) and outdoor air temperature of 7°C Dry Bulb 
(44.6°F Dry Bulb), 6°C Wet Bulb (42.8°F Wet Bulb) 
3.  Heating low temperature capacity, Input Power and COP measured at 230 V, indoor temperature of 20°C, outdoor 2/1°C. 
4.  Heating extreme low temperature capacity, Input Power and COP measured at 230 V, indoor temperature of 20°C, outdoor -7/-8°C. 
5.  Standby power consumption ≤ 2.0W (when switched OFF by remote control, except under self-protection control). 
6.  Specifications are subjected to change without prior notice for further improvement. 
7.  Maximum heating capacity shown are the values based on powerful operation. 
8.  If the EUROVENT Certified models can be operated under the “extra-low” temperature condition, -7°C DB and -8°C WB temperature with 
rated voltage 230V shall be used. 
9.  The annual consumption is calculated by multiplying the input power by an average of 500 hours per year in cooling mode. 
10.  SEER and SCOP classification is at 230V only in accordance with EN-14825. For heating, SCOP indicates the value of only Average heating 
season. Other fiche data indicates in an attached sheet.
