DETERMINING THE BASE IMPURITY RATEFor the first 30 seconds after the power plug is inserted into the wall outlet, the unit will check the conditions of the air. If operation is set to ON during this time, the CLEAN-SIGN LIGHT will alternately flash in green, orange and red.
CLEAN-SIGN LIGHT
The color changes according to the air condition.| Clean (Green) | Slightly Impure (Orange) | Very Impure (Red) |
ABOUT THE CLEAN-SIGN•The condition of the CLEAN-SIGN depends on the room air condition detected by the Dust Sensor when the plug is inserted into the wall outlet.
•It is possible to have a green CLEAN-SIGN with impurities in the air at the time that the air purifier was just introduced to the room environment. After a while, however, the base impurity rate will be adjusted to detect room air condition correctly.
CLEAN FILTER INDICATOR LIGHT
Clean the Pre-Filter when the CLEAN FILTER Indicator Light activates. (The indicator light will activate in about 2 months, when using the unit 24 hours daily.)
Be sure to press the MODE selection Button for 3 seconds after cleaning the pre-filter. A long beep will be heard and the operation hours stored in the memory will be reset. Then the Filter Indicator Light will go out automatically.
