Eco Saving Operation
When the air is clean and "Silent" airfl ow rate operation continues for 10 minutes or longer, the fan stops for about
50 minutes and the unit intermittently operates using "Silent" for about 10 minutes.
If this status continues for longer than 8 hours, the unit will automatically stop operating.
* During eco saving operation, the level of air contamination is detected by the odor and dust sensors. When the
sensors detect odors and dust, the airfl ow rate will switch depending on the level of air contamination.
When the air is clean and the "Silent" airfl ow rate operation continues for 10 minutes or longer, the unit will start in-
