NOTES:
• Specifications are based on the following conditions:
– Cooling: Indoor temperature of 80 °FDB (26.67 °CDB) / 67 °FWB (19.44 °CWB), and outdoor temperature of 95 °FDB (35 °CDB) / 75 °FWB (23.9 °CWB).
– Heating: Indoor temperature of 70 °FDB (21.11 °CDB) / 59 °FWB (15 °CWB), and outdoor temperature of 47 °FDB (8.33 °CDB) / 43 °FWB (6.11 °CWB).
– Pipe length: 24 ft 6 in (7.5 m), Height difference: 0 ft (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.

Unit: in (mm)
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 69.
