The following situations have logical explanations.
Before requesting servicing, make the following checks.
Humidity in rooms facing north or rooms near plumbing fi xtures 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 fi lter.
Check
The dust and odor sensor lamps are fl ashing?
Is the humidifying tray out of place?
(The water supply lamp is fl ashing.)
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 fl ow?
Has a lot of dust accumulated on the pre-fi lter and/or
pleated fi lter?
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?
