Before Requesting Service
The air purifier does not operate.
•
Make sure that the front panel is closed properly.
If you hear a “beep” or “ring ring” sound when the
front panel is opened and closed, it indicates that
the panel is closed completely.
There is no change in air polution level
on the display.
•
To check if the sensor is
functioning, test it by tearing
paper by the sensor and/
or rub them to create some
dust. This will cause the
PM levels to change if the
sensor is working properly.
•
The gas sensor reacts to changes in the indoor
odourant level due to cooking or ventilation,
causing the indicator to illuminate in red. When this
happens, ventilate the room for 1 to 2 hours.
•
Disconnect the power plug, then put it back after 1
minute.
•
The dust concentration may vary depending on the
operating environment.
‐ Construction site, road area, use of vacuum
cleaner, organizing of quilts/clothes, fabric sofa
area, etc.
•
The gas pollution reading can be affected by
odorous household items such as air fresheners,
deodorants and detergents.
•
If you are using more than one air purifier in the
same room, the dust concentration reading on each
unit may not be same as they affect air circulation.
The dust concentration reading may vary depending
on the sensor or product being used.
•
When humidifiers, electric pressure cookers,
sprayers and such are being used in the same room,
the pollution level may be measured as Poor.
The pollution level indicator does not
seem to work.
•
Check the sensors for any foreign substances and
clean them if necessary.
•
During initial operation after shipping or installation
in winter, dew condensation may occur inside the
sensor due to the temperature difference between
inside and outside, which may cause the dust
concentration to temporarily display high or the air
pollution indicator may light up in red. The status
will be cleared within 1 to 2 hours of operation.
The air purifier makes strange noises.
•
If you move the product during operation, it may
cause noise. Turn off the power before moving the
product.
The air purifier smells strange.
•
If you operate the product after using an air freshener, a
diffuser, a scented candle, or a cleaning agent, or making
interior decoration, or replacing wallpaper, odours may
be saturated to the filters, making them smell.
•
Because the air purifier sucks and circulates indoor air,
if you use it in a closed space for a long time, odours
generated in your home can saturate the filters.
‐ Remove the filter and then smell it nearby. If
it smells, clean the micro filter and replace the
replacement filter with a new one.
‐ Open the doors and windows, and then operate the
product for 3 to 4 hours.
‐ If you grill fish or meat or cook with oil, operate the
product after most odours have been removed by
ventilation.
•
In a room with persisting odours, using the product after
ventilating the room first allows more effective odour
control.
•
In a humid place, the filter may smell. Dry the
replacement filter sufficiently in the sun before
operation.
The filter replacement reminder stays on.
•
After replacing with a new one, be sure to perform
Filter Reset to clear the filter replacement reminder.
