a ventilation effect (remov-
al of carbon monoxide
and other contaminants).
* The purifier cannot re-
move harmful substanc-
es in cigarettes (carbon
monoxide, etc.).
Refrain from placing any ob-
ject on the unit and blocking
the air inlet and outlet
Doing so may cause unit failure
and injury.

less phones and wireless mi-
crophones.
Safety Precautions Cautions on Use Air Cleaner Deodorizing Performance
Air Cleaner Deodorizing Performance
The filter of the air purifier does not remove all odors at once, but rather circulates the air in the room, re-
moving odors gradually.
The filter is disposable. The deodorizing performance of the filter decreases with use.
When the odor emitted from the vent becomes bothersome, clean the filter. (P.E-23)
When the filter has absorbed strong odors or has been continually used in an odorous room, the odor com-
ponents remain in the filter and unit, causing the odor to be emitted from the vent.
If this happens, you can decrease the amount of odor that remains in the unit by continuing to operate the
purifier while ventilating the room.
The dust and other contaminants attached to the filter and unit also contain odor components.
Periodically clean the filter and unit so that odor is less likely to be emitted from the vent. (P.E-23, E-24)
If the odor emitted from the vent remains bothersome after cleaning, replace the filter. (P.E-25)

Preparations for Operation

Movement with casters should be done slowly. The movement is only in sideways direction. (To prevent from falling)

No cleaning effect will be experienced if the filter is set without detaching the plastic cover. It will also cause unit failure.
Do not tip over or tilt the unit.

The unit will operate on “Max” airflow rate for the first five minutes (flap direction: upward), then it will operate for
about 55 minutes in “High” airflow rate (flap direction: swing (30 minutes) upward), and the unit will stop operating
afterwards.
Use this to clean the room air while away.
The unit automatically stops operation when the air becomes clean, saving electricity cost. (P.E-19)

Useful Features
Eco Saving Operation
The unit automatically stops operation when air becomes clean, saving electricity cost.
Also, if this status continues for longer than 8 hours, the unit will automatically stop operating.
Normal Auto Operation
When the air is clean, the unit will continuously operate in “Silent” airflow rate and not stop.
Eco Saving Operation
When the air is clean and “Silent” airflow 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 airflow rate will switch depending on the level of air contamination.
When the air is clean and the “Silent” airflow rate operation continues for 10 minutes or longer, the unit will start
intermittent operation again.

Note
Operation modes other than “Air Purify” cannot be set.
While operating in PM2.5 sensing, the air sensor will light up, then enlarge and shrink slowly.
For the first 90 seconds of operation, the unit will operate in “Max” airflow rate (air sensor: red).
The flap direction will be diagonal.
It will not respond to the switching of sensor sensitivity. (P.E-22)
Change into a sensor that is suitable for small particles, like PM2.5 (general term for micro particles be-
low 2.5µm). The level of contamination in the air will be detected by the dust sensor, and the unit will op-
erate automatically between “Medium” to “Max” airflow rate.
(Odor sensor control will not be performed)
