Phenomenon
The HUM monitor lamp always
indicates a high humidity level
The humidity level indicated on the
unit differs from other hygrometers
Ambient humidity does not rise
Room humidity is high but
Humidifying operation does not stop
Water in the water tank is decreasing
even though Humidifying operation is
not running
Water splashes out from the air outlet
• 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.
• 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.
• When indoor or outdoor humidity is low, the walls and floor 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
Is the FAN setting set to
¼ Select the humidity setting
• When indoor or outdoor humidity is high, the walls and floor of the room are
moist, or the room has good insulation against drafts, the target humidity
may be exceeded.
• Air purification 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.
• 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 humidification.
When using the Air purifying operation only, discard any water in the water
tank and humidifying tray.
• Are the pre-filter, outflow grille, dust collection filter, humidifying filter,
and water tank properly attached?
¼ Attach them properly.
• When removing the humidifying filters from their frames and replacing
them, did you do the following?
• Correct the shape of the filters
• Attach both filters
• Attach the filters to the frames so that the colour and weaving
pattern of each filter matches the markings on the frame
¼ Attach them properly.
Check points
(Low) or (Standard)?
