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: 7.5 m, Height difference: 0 m. (Between outdoor unit and indoor unit.)
• This data is based on following standard: EN14511, EN12102.
• Protective function might work when using it outside the operation range.
• *: 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.
