1 Specifications
Notes Nominal cooling capacities are based on : indoor temperature : 27°CDB, 19°CWB, outdoor temperature : 35°CDB,
equivalent refrigerant piping : 7.5m (horizontal)
Nominal heating capacities are based on : indoor temperature : 20°CDB, outdoor temperature : 7°CDB, 6°CWB,
equivalent refrigerant piping : 7.5m (horizontal)
Capacities are net, including a deduction for cooling (an addition for heating) for indoor fan motor heat.
External static pressure is changeable to set by the remote control; this pressure means : high static pressure -
standard static pressure.
The operation sound levels are conversion values in anechoic chamber. In practice, sound levels tend to be higher
than the specified values due to ambient noise or reflection. When the suction place is changed to bottom suction,
sound level will increase
