Humidifying function
Phenomenon Check points
The HUM monitor lamp always
indicates a high humidity level
• Is the unit positioned next to a window or in a location exposed to
cold wind?
¼
There is a possibility that only the air surrounding the unit is of high
humidity. Try moving the unit to a different location.
• North facing rooms or rooms close to wet areas, such as the bathroom,
become humid easily, so these rooms tend to have a higher humidity.
The humidity level indicated on the
unit differs 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.
Ambient humidity does not rise
• When indoor or outdoor humidity is low, the walls and oor of the room are
dry, or the room has poor insulation against drafts, the target humidity may
not be readily achieved.
• Are you using the unit in a room with an area larger than applicable?
►

• Is the target humidity set to (Low) or (Standard)?
Is the FAN setting set to
(Quiet) or (Low)?
¼
Select the humidity setting
(High) and increase the airow rate.

Room humidity is high but
Humidifying operation does not stop
• When indoor or outdoor humidity is high, the walls and oor of the room are
moist, or the room has good insulation against drafts, the target humidity
may be exceeded.
• Air purication is always performed with the Humidifying operation. When
the humidity set for the Humidifying operation is reached, the Humidifying
operation stops but the Air purifying operation continues.
• Is the unit exposed to direct sunlight or warm air from a heating
appliance?
¼
Move the unit to a location without such direct exposure.
Water in the water tank is decreasing
even though Humidifying operation is
not running
• Even when only the Air purifying operation is running, if there is water in the
water tank, the water may decrease due to spontaneous evaporation
caused by air currents and result in slight air humidication.
When using the Air purifying operation only, discard any water in the water
tank and humidifying tray.
Water splashes out from the air outlet
• Are the pre-lter, outow grille, dust collection lter, humidifying lter,
and water tank properly attached?
¼
Attach them properly.
• When removing the humidifying lters from their frames and replacing
them, did you do the following?
• Correct the shape of the lters
• Attach both lters
• Attach the lters to the frames so that the colour and weaving
pattern of each lter matches the markings on the frame
¼
Attach them properly.
