*Note, during Economy operation and operation mode is Fan, air flow is 1 step downs. (Hi > Me, Me > Lo, Lo > Quiet, Quiet > Soft Quiet)

2. FAN OPERATION

The airflow can be switched in 5 steps such as Auto, Quiet, Lo, Me, Hi, while the indoor fan only runs. When fan mode is set at [Auto], it operates on [Me] fan Speed.

3. COOLING OPERATION

Switch the airflow [Auto], and the indoor fan motor will run according to a room temperature, as shown in Fig4. On the other hand, if switched in [Hi] [Quiet], the indoor motor will run at a constant airflow of [Cool] operation modes Quiet, Lo, Me, Hi, as shown in Table 6.

4.DRY OPERATION

Refer to the Table 6.

During the dry mode operation, the fan speed setting can not be changed.
