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.

stacle.
• When installing the outdoor unit, be sure to open the front and left side to obtain better operation
efficiency.
CAUTION
• Do not install the outdoor unit in two-stage where the drain water could freeze. Otherwise the
drainage from the upper unit may form ice and cause a malfunction of the lower unit.
• When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe and drain
cap. If the drain pipe and drain cap are used, the drain water in the pipe may freeze in extremely
cold climate. (For reverse cycle model only.)
• In area with heavy snowfall, if the inlet and outlet of the outdoor unit is blocked with snow, it
might become difficult to get warm, and it is likely to cause product malfunction. Construct a
canopy and a pedestal, or place the unit on a high stand that is locally installed.
