not be a malfunction of the unit.
SYMPTOM
REMEDY (not a malfunction)
The remote control does not
work
• Has the batteries depleted?
• Are the batteries inserted with correct polarity?
• Is a fluorescent lighting in the room flickering due to
service life?
Odors and smoke cannot be
removed easily
• Are the filters heavily dirty?
The Clean sign lights green
even when the air is dirty
• Is the opening of the dirt sensor blocked or clogged?
• Was the air already dirty when the power plug was
inserted into the wall outlet? (Refer to E-4)
• Dirt sensor cannot detect pollen and dust without
smell.(Refer to E-4)
The Clean sign lights orange
or red even when the air is
clean
• The sensitivity of the sensor becomes unstable when
the opening of the dirt sensor is dirty or is clogged.
Clean the dust around the sensor opening using a
vacuum cleaner.
• Dirt sensor detects insecticide, cosmetics,spray or al-
cohol as well. It is not a malfunction.
The cluster ion lamp remains
green (blue) and does not
change
• During the Clean mode (or Refresh mode), the clus-
ter ion lamp color will not change.
A sound is
heard from
the unit
Click, click
Tick, tick, tick
• This is the sound that is emitted when the unit is in
the Refresh mode.
If the sound is irritating, switch the unit to the Clean
mode.
• This is the sound that is emitted when the unit is gen-
erating cluster ions.
If the sound is irritating, such as when sleeping, etc.,
set the Cluster ion mode to OFF.
The discharged air smells
• The ozone generated by the cluster ion generator may
have an odor. However, the density of ozone gener-
ated is very little and is harmless to the human body.
Furthermore, the ozone decomposes quickly so it does
not accumulate in the room.
