1 Features
IndoorUnit SplitSky FLKS-BAVMB R410A •Slim&smart
• Lightweight but sturdy design
• Can fit on either ceiling or lower wall. Its low height enables it to fit
beneath a window
• The home leave operation saves energy during absence
• Powerful mode can be selected for rapid cooling
• Auto-swing function ensures efficient air and temperature
distribution.
• Air purification filter: deodorises the air and helps to prevent bacterial
and viral propagation
• The photocatalytic deodorising air filter: powerfully decomposes
cigarette and pet odours, removes house dust and pollen and
deactivates bacteria and viruses
• Washable front panel
• Indoor unit silent operation: "Silent" button on the remote control
lowers the operation sound of the indoor unit by 3dB(A) (only if
connected to a DC inverter controlled outdoor unit)
• Easy to install
• Up to 4 indoor units can be connected to 1 Multi outdoor unit. All
indoor units are individually controllable with remote control and do
not need to be installed in the same room or at the same time. They
operate simultaneously within the same cooling m
• Daikin remote controls give you easy control at your fingertips.
• The remote control has a 24-hour timer
• The indoor unit also has a start/stop button mounted on the front
panel
• Up to 5 indoor units can be operated from a single centralised control
• Purpose-designed holder provided for your remote control

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.
