(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 1 m in front of the main body and 0,8 m below the unit. For outdoor unit 1 m in front and 1 m 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 70 mm for piping port.
(6) When installing the outdoor unit at a higher position than the indoor unit.

* Only one of these can be used at a time.
