Notes Nominal cooling capacities are based on: indoor temperature: 27°CDB/19°CWB, outdoor temperature: 35°CDB,
equivalent refrigerant piping: 7,5m, level difference: 0m.
Nominal heating capacities are based on: indoor temperature: 20°CDB, outdoor temperature: 7°CDB/6°CWB,
equivalent refrigerant piping: 7,5m, level difference: 0m.
Sound power level is an absolute value that a sound generates.
Sound pressure level is a relative value, depending on the distance and acoustic environment. For more details,
please refer to sound level drawings.
Sound values are measured in a semi-anechoic room.
