Memory Function / Monitor / Sensors / Auto Detection

Memory Function

 When
power button is turned on, the unit operates the previous operation mode set prior to turning off.

Clean monitor

 The level of air contamination detected by the odor
and dust sensors is indicated by different colors.
Display Color : Blue
Dirtiness Level: Clean
Note
 When the unit is placed in a location where contamination is diffi cult to detect, or when the sensor needs cleaning,
the display color may not change.

Odor Sensor

 This sensor detects odors and VOC in the air, such as cigarette smoke and pet odors.
Even if you think the air is clean, the unit may continue the operation if the odor sensor
detects any gas component that has not been removed by the fi lter.
Also, any of the following may be detected by the odor sensor.
· Combustion gases from heating appliances during use, alcohol, odor of perfumes or
cosmetics used in beauty parlors or aesthetic salons, sprays, vapors, abrupt tem-
perature changes, etc.

Dust Sensor

 This sensor detects particulates in the air, such as PM2.5, cigarette smoke, house
dust, and pollen.
The dust sensor may fail to sense dust stirred up when you lay out or put away bed-
ding, which contains signifi cantly fewer contaminants than cigarette smoke, etc. In
such a case, the clean monitor display may appear to be different from the appar-
ent dust in the air.
 The dust sensor may not function properly if the sensor is dirty.
Carry out periodical cleaning of the dust sensor and the parts around it.

Auto Detection

 The air purifi er performs automatic operation by detecting room air contamination using the "Odor Sensor" and "Dust
Sensor".
During the fi rst 3 minutes after the power is turned on, the unit will check the air condition of the room.
 The purifi er operates even while it checks the air condition of the room.
During this time, the "Clean Monitor" lights up in white.
 After checking the air condition, the "Clean Monitor" will display the room air contamination using the "Odor Sen-
sor" and the "Dust Sensor".
 If you plug in the power cord in an environment containing contaminated air, the sensitivity of the sensor may be
reduced.
To clean the air of the room, operate in "High" or "Rapid". Or open a window and unplug the power cord from the
AC outlet when ambient air is clean and plug it back in after 10 seconds.
