door Uni it - Sk -K r applic
Out Spl RXS Pai • Energy efficient units: up to class A energy labels
• Seasonal efficiency, optimized for all seasons.

• Seasonal efficiency gives an indication on how efficient an air conditioner operates over an entire heating or cooling season.

• Compact casing (575mm in width and depth) enables unit to fit flush into ceilings and match standard architectural modules, without cutting ceiling tiles

• Modern style decoration panel in white (RAL9010)

• Whisper quiet operation: down to 24.5dBA sound pressure level

• Comfortable vertical auto swing ensures draughtfree operation and prevents ceiling soiling

• Fresh air intake for healthy living

• Since the flaps can move to a 0 degree position, virtually no draught can be experienced

• Possibility to shut 1 or 2 flaps for easy installation in corners

• Easy maintenance: switch box can be reached by simply removing the suction grille

• Standard drain pump with 750mm lift

• No optional adapter needed for DIII-connection: standard plug and play connection with centralised control systems, intelligent touch controller, intelligent manager, ...

• Outdoor units for pair application

• Energy efficient units: full range A class energy labels

• Daikin outdoor units are neat, sturdy and can easily be mounted on a roof or terrace or simply placed against an outside wall

• Energy saving during standby mode: reduces current consumption by about 80% when operating In standby. If no people are detected for more than 20 minutes, the system will automatically switch to the current-saving mode.

• Outdoor unit silent operation: "silent" button on the remote control lowers the operation sound of the outdoor unit by 3dBA to ensure a quiet environment for the neighbourhood.

• Outdoor units are fitted with a swing compressor, renowned for its low noise and high energy efficiency

• Anti-corrosion treated outdoor heat exchanger fin

• Split - Sky Air® • Outdoor Unit
