Check Before Requesting Servicing

Troubleshooting
If this happens
The current humidity remains high.
The readings of the room hygrometer and
unit's humidity indicator lamp differ.
A catching sound is heard during operation.
The sound of water is heard during operation.
A splashing sound is heard during operation.
If this happens
Does not operate.
The airflow rate
"high", "standard",
"low" and "quiet"
lamps all flash at
the same time.
The unit does not
blow air.
Both the dust and
odor sensor lamps
are flashing a red
color.
Air is not cleaned.
The TV picture is
distorted.
Humidifying Air Purifier
The following situations have logical explanations.
Before requesting servicing, make the following checks.
Humidity in rooms facing north or rooms near plumbing fixtures such as
bathrooms is normally high because moisture readily accumulates.
This is because air currents cause temperature and humidity drifts even in the
same room. Consider the humidity indicator lamp as just a reference reading.
A catching sound is made when humidifying operation starts and stops.
The sound of water may be heard as water is supplied from the water
tank to the humidifying tray.
This is the sound of water from the waterwheel splashing on the
humidifying filter.
Check
The dust and odor sensor lamps are flashing?
Is the humidifying tray out of place?
(The water supply lamp is flashing.)
Is the front panel or UNIT1 improperly set?
Are the projections on the backside of the front
panel damaged?
Is there any foreign matter in the air outlet?
Is the unit leaned in excess or toppled?
Is the unit located where air does not reach the entire
room or is something obstructing the air flow?
Has a lot of dust accumulated on the pre-filter
and/or pleated filter?
Is the room overly smelly or smoky?
•Is a television or radio installed within 2m of
this unit or is an indoor antenna being used
close to this unit?
•Is the power supply cord or antenna of the
television or radio close to this unit?

ON/OFF button.
Select an unobstructed location from where air
