Notes Sound pressure level is a relative value, depending on the distance and acoustic environment. For more details,
please refer to sound level drawings of this chapter.
The sound power level is an absolute value indicating the power which a sound source generates.
Sound values are measured in a semi-anechoic room.
In case of drain piping for outdoor unit, drain piping kit (option) is needed.
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
