• Have the batteries been depleted?
• Are the batteries inserted correctly?
• Is a fluorescent lighting in the room flickering due to service
life? (Refer to E-3,E-7)
• Are the filters heavily soiled? (Refer to E-14)
• Is the opening of the odor sensor blocked or the sensor filter
clogged? (Refer to E-13)
• Was the air already dirty when the power plug was inserted
into the wall outlet? (Refer to E-5)
• Is the sensor filter dirty or clogged?
The sensitivity of the sensor becomes unstable when the open-
ing of the dust sensor is dirty or is clogged.
Remove dust from the sensor filter. (Refer to E-13)
• During Clean mode (or Ion control mode), the cluster ion lamp
colour will not change.
Click, click
• This is the sound that is emitted when the unit is in Ion control
mode.
If the sound is irritating, set the unit away from you.
Tick, tick, tick
• This is the sound that is emitted when the unit is generating
cluster ions.
If the sound is irritating, such as when sleeping, set the unit
away from you.
• A sound is sometime low, loud or none. But the effect of the
cluster ion is the same.
• Are the filters heavily soiled?
Replace the filters. (Refer to E-14)
• The ozone generated by the cluster ion generator may have
an odor. However, the density of ozone generated is very little
and is harmless to the human body. Furthermore, the ozone
decomposes quickly so it does not accumulate in the room.
• Is the unit installed in a location that is difficult for the sensors
to detect cigarette smoke?
• Are the odor or dust sensor openings blocked or clogged?
(In this case, clean the openings.) (Refer to E-13)
• After replacing filters, connect the power plug to a wall outlet,
and press the filter reset button on the main unit or on the
remote control. (Refer to E-14)
• Is DISPLAY OFF mode selected?
• Press the DISPLAY ON/OFF button on the remote control.
