NOTES:
• Specifications are based on the following conditions:
– Cooling: Indoor temperature of 27 °CDB/19 °CWB, and outdoor temperature of 35 °CDB/24 °CWB.
– Heating: Indoor temperature of 20 °CDB/15 °CWB, and outdoor temperature of 7 °CDB/6 °CWB.
– Pipe length: 5 m, Height difference: 0 m. (Between outdoor unit and indoor unit.)
• Protective function might work when using it outside the operation range.
• *1: Maximum operating current is the total current of the indoor unit and the outdoor unit.
• *2: Sound pressure level:
– Measured values in manufacturer’s anechoic chamber.
– Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specified values here.
• *3: Available on Google Play™ store or on App Store®. Optional WLAN adapter is also required. For details, refer to the setting manual.

NOTES:
• To set “3-direction”, optional Air outlet shutter plate (UTR-YDZK) must be installed, and the “out-
let-direction” need to be switched to “3-way” by remote controller.
*: When installing the indoor unit, be careful about the maintenance space.
• The ceiling height cannot be set in the 3-way outlet mode. Therefore, ceiling height setting
change by function setting 20 is prohibited. For details, refer to "Contents of function setting" on
page 34.
