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.  Network Impedance shall be applicable for Europe models only. 
4.  The annual consumption is calculated by multiplying the input power by an average of 500 hours per year in cooling mode. 
5.  EER and COP Class: Refer Att 11, RAD-A-04-06, eg. Europe: classification is at 230V only in accordance with EU directive 2003/31/EC,  
A – G, Australia: n star, Singapore: Tick n, etc. 
6.  Heating low temperature capacity, Input Power and COP measured at 230 V, indoor temperature 20°C, outdoor 2/1°C. 
7.  Heating extreme low temperature capacity, Input Power and COP measured at 230 V, indoor temperature 20°C, outdoor -7/-8°C. 
8.  Standby power consumption ≤2.0W (when switched OFF by remote control, except under self protection control). 
9.  Specifications are subjected to change without prior notice for further improvement. 
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.
