• Do not clean the sensors using volatile substances (alcohol, acetone, etc.). Use only water.
CAUTION • If the dust sensor lens or the odor sensor is contaminated by a foreign substance (dust), the cleanness indicator of the air purifier may be stuck in the polluted state. In this case, clean the sensors.
•Clean the sensors at least once every 6 months. However, cleaning period should be different depending on the operating environment and the operating time. Therefore cleaning should be more often in places with lots of dusts.
•Cleanness indicator on the control panel may not change from polluted state when the air purifier is operating in place with heavy dusts or smells that may be beyond its capability. (In this case, open the window to ventilate,
or use the air purifier with appropriate capacity.)
•Do not use any spray type product near the air purifier.
•Turn off the power when cleaning the sensors. If you clean the sensors while the power is on, misdetection may occur from the sensor and the cleanness indicator may not work properly.
