ance at least 1m apart from each other.
Ventilate closed rooms occasionally
The purifier does not have
a ventilation effect (remov-
al of carbon monoxide
and other contaminants).
* The purifier cannot re-
move harmful substanc-
es in cigarettes (carbon
monoxide, etc.).
Refrain from placing any ob-
ject on the unit and blocking
the air inlet and outlet
Doing so may cause unit failure
and injury.

The same applies for cord-
less phones and wireless mi-
crophones.
Safety Precautions Cautions on Use Air Cleaner Deodorizing Performance
Air Cleaner Deodorizing Performance
The deodorizing filter of the air purifier does not remove all odors at once, but rather circulates the air in the
room, removing odors gradually.
The deodorizing filter is disposable. The deodorizing performance of the filter decreases with use.
When the odor emitted from the vent becomes bothersome, soak and wash the deodorizing filter. (P.E-41)
When the deodorizing filter has absorbed strong odors or has been continually used in an odorous room,
the odor components remain in the filter and unit, causing the odor to be emitted from the vent.
If this happens, you can decrease the amount of odor that remains in the unit by continuing to operate the
purifier while ventilating the room.
The dust and other contaminants attached to the filter and unit also contain odor components.
Periodically clean the filter and unit so that odor is less likely to be emitted from the vent. (P.E-40 - E-42)
If the odor emitted from the vent remains bothersome after cleaning, replace the filter. (P.E-43, E-44)

Preparations for Operation

Movement with casters should be done slowly. The movement is only in sideways direction. (To prevent from falling)
