Duct Connected Type
50Hz 230V
Note:
1. The operating sound is based on the rear side suction inlet and the external static pressure 40 Pa.
Operating sound for under side suction inlet: [operating sound for rear side suction inlet]+5 dB.
However, when installation to which the external static pressure becomes low is carried out,
5 dB or more may go up.
