1 Features
IndoorUnit SplitSky FTXG-EV1BW_FT R-410A • State of the art design: sleek, compact and stylish outlook
• Superb energy efficiency
• Available in 2 colour variations: mat crystal white and mat crystal
silver
• Newly designed air distribution flap prevents draft feeling by
activating the ’comfort mode’
• The new titanium apatite photocatalytic air purification filter increases
the active surface area for effective purification and deodorisation
• Horizontal and vertical auto-swing + 3D-air flow ensure efficient air
and temperature distribution.
• Powerful mode can be selected for rapid cooling or heating
• The movement sensor saves power consumption in unoccupied
rooms
• Indoor unit silent operation: "Silent" button on the remote control
lowers the operation sound of the indoor unit by 3dB(A).

Notes Sound values are measured in an anechoic room.
Sound pressure level is a relative value, depending on the distance and acoustic environment. For more details,
please refer to sound level drawings of this chapter.
The sound power level is an absolute value indicating the power which a sound source generates.
