Names of Parts and Operations
Dust sensor lamp/PM2.5 sensor lamp
Indicates the volume of ambient dust in 3 colours:
blue, orange, red.
• Blue indicates that the air is clean.
•
The dust/PM2.5 sensor can detect small (about 1.0-
2.5μm) and large (about 2.5μm and above) dust particles.
The PM2.5 lamp lights in response to small particles and
the dust lamp lights in response to large dust particles.

After operation is started, the lamp will light blue for
about the first minute regardless of air impurity level.
If the responsiveness of the dust/PM2.5 sensor is poor,
change the sensitivity setting of the sensor.

If the airflow rate setting is set to “Turbo”, the
responsiveness of the dust/PM2.5 sensor may be poor.
The strong airflow causes dust to be drawn into the air
inlets before it can be detected by the dust/PM2.5 sensor.
This is normal (not a malfunction).
Dust/PM2.5 sensor detection range
Detectable matter
house dust, tobacco smoke, pollen, mite droppings and
remains, pet hairs, diesel particulate matter
Sometimes detectable
steam, oil smoke
Front indicator lamps
HUM monitor lamp (about ambient humidity)
[blue]
Indicate room humidity within the range 20%-90%.
(1% increments)
When the humidity level is below 20%, “20” is displayed.
When the humidity level is above 90%, “90” is displayed.
•
The lamp will light up even when only the Air purifying
operation is active.
•
[– –] is displayed for about 30 seconds immediately after
operation start regardless of the humidity.
• If there is a power failure, then power is restored and
operation is started again, [– –] is also displayed for about
30 seconds.
At times the humidity level indicated on the unit may
differ from other hygrometers.
•
This is because the flow of air causes temperature and
humidity to vary throughout the room. Please consider
the indications to be a rough estimate of ambient
humidity.
