• Outdoor units for pair application
• Daikin outdoor units are neat and sturdy and can be mounted easily on
a roof or terrace or simply placed against an outside wall.
• Outdoor units are fitted with a scroll compressor, renowned for low
noise and high energy efficiency.
• The piping connections can be accessed from underneath, front, side or
rear.
• The sevice valves are hidden inside the casing.
• A special acryl precoated fin for anti-corrosion treatment on the heat
exchanger ensures greater resistance against severe weather conditions

NOTES
1 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.
2 The sound power level is an absolute value indicating the power which a sound source generates.
3 Sound values are measured in a semi-anechoic room.
4 In case of drain piping for outdoor unit, drain piping kit (option) is needed.
5 Nominal cooling capacities are based on : indoor temperature : 27°CDB, 19°CWB, outdoor temperature : 35°CDB, equivalent refrigerant piping : 7.5m,
level difference : 0m.
6 Nominal heating capacities are based on : indoor temperature : 20°CDB, outdoor temperature : 7°CDB, 6°CWB, equivalent refrigerant piping : 7.5m,
level difference : 0m
