1) EER and COP calculation is based in accordance to EN14511.
2) Energy Label Scale from A+++ to D.
3) The annual energy consumption is calculated in accordance to EU/626/2011.
4) The sound pressure of the indoor unit shows the value measured of a position 1m in front of the main body and 0,8m below the unit. For outdoor unit 1m in front and 1m in rear side of main body. The sound pressure is measured in accordance with JIS C 9612. Q-Lo: Quiet mode. Lo: The lowest set fan speed.
5) Add 70mm for piping port.
6) When installing the outdoor unit at a higher position than the indoor unit.
