FAQs
Please check the following before contacting the place of purchase.
Q: The value displayed as the PM2.5 concentration is always low and seems unresponsive, or the
sensitivity of the PM2.5 sensor seems to be poor...
A:
Perform periodic cleaning of the PM2.5 sensor as dirt on its lens can lead to poor
sensitivity.
►Page 27
In addition, the response time of the PM2.5 sensor depends on the room size.
Make adjustments in accordance with the procedure for setting PM2.5 sensor
sensitivity.
►Page 23, 24
The responsiveness of the PM2.5 sensor may be poor during FAN setting Turbo or
when airfl ow is High in AUTO FAN MODE.
The strong airfl ow causes dust to be drawn into the air inlet before it can be
detected by the PM2.5 sensor. This is normal (not a malfunction).
Q: Can the dust collection fi lter be cleaned with water?
A:
No. Do not attempt to clean it with water.
(Reduced performance of the dust collection fi lter may result)
Replace it or vacuum away dust with a vacuum cleaner if dirt buildup is severe.
►Page 28, 29
In some cases, odour is stuck to the dust collection fi lter depending on the location
where the unit is used. If the odour becomes severe, replace the fi lter, or vacuum
away dust with a vacuum cleaner.
Q: Dust collection fi lter easily turns black...
A:
The blackening does not affect dust collection performance.
However, it can be replaced if it is an issue.
Can the deodorising fi lter be cleaned with water? Or should it be replaced?
A:
It cannot be cleaned with water.
(If water is used, the part will lose its shape and become unusable)
If you have inadvertently washed it with water, contact the place of purchase.
Remove the deodorising fi lter from the unit and vacuum off dust with a vacuum
cleaner.
It is not necessary to replace the fi lter.
In some cases, odour is stuck to the deodorising fi lter depending on the location
