  • *1Minimum connectable indoor unit number is 2.
    However ARXC72 and ARXC90 can be used signal connection.
  • *2The noise value is the value when measured in an anechoic room.
    When measured in the actual installed state, surrounding noise and reflections are received and the measured value is usually larger than the indicated value.
  • Note : Specifications are based on the following conditions.
  • Cooling : Indoor temperature of 27°CDB / 19°C, and outdoor temperature of 35°CDB / 24°C.
  • Heating : Indoor temperature of 20°CDB / (15°C), and outdoor temperature of 7°CDB / 6°C.
  • Pipe length : 7.5 m; Height difference between outdoor unit and indoor unit : 0 m.
    When cooling operation will be conducted at outdoor air temperature below -5°C, the outdoor unit must be installed in a position that is higher than or equal to those of indoor units.
