(Max: Upper fan: 890 rpm / Lower fan: 910 rpm (WF)).
In this case, the upper limit value of static pressure for duct is 5Pa

or less on 77°F (25°C) degrees and please use straight duct.
In this case, the outdoor noise level may increase.

Turn the switch to ON when using the power save function.
The control to lower the compressor frequency (Approx. –10%) is

performed by indoor heat exchanger temp. in heating operation.

When snow enters from clearance of the fan guard or heat

exchanger into blast path and it is accumulated, the control to

prevent generation of motor lock is validated.
When outside temp. is below 32°F (0°C) though the compressor

stops, the outdoor fan operates with W5.

The defrost interval is cut to shorten it than the standard status.
For contents of control and cutting method, refer to
