Cleanliness
The cleanliness colour indicator continuously lights up in red.
(The cleanliness indications are strange.)
• Check the sensors for any foreign substances and clean them if
necessary.
• In winter season, installing and operating the product for the
rst time shortly after delivery may cause the pollution level
to reach 999/m³ with the indicator illuminated in red. This
is a temporary issue that happens if there is a signicant
temperature change from outdoor exposure causing
condensation inside the unit. In this case,
do not be alarmed and continue using the product. The status
will be cleared within 1 to 2 hours of operation.
• 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. (To
reset the sensor)
• If the indicator colour stays in red after you have followed all the
provided instructions and solutions, it may be a sensor issue. In
this case, please contact your local Samsung Service Centre.
• When humidiers, electric pressure cookers, sprayers and such
are being used in the same room, the pollution level may be
measured as Poor.
The fan speed does not change according to cleanliness.
• Set the fan speed to Auto. The fan speed does not change
automatically when it is set to Low, Medium or High, and when
Sleep mode is on.
The PM10, PM2.5, PM1.0 concentration values do not change
from the Good (05) level.
• This may happen when the room is properly sealed and the air is clean.
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.
– Dusting off or cleaning the room may not necessarily cause
sensor feedback if the dust particles are bigger than PM10,
while they are still ltered and removed from the air.
