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 current is maximum value when operated within the operation range.
• *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.
