The washable photocatalytic filter has a two-layer
construction consisting of a white particle filter and a blue
air-freshener filter.
The fine particle filter removes pollen* and dust particles.
The special air-freshening agent contained in the fibres of
the air-freshener filter absorbs odorants such as ammonia.
The odor is broken down by photocatalysis renewing the
air-freshening properties.
As the filter’s particle and air-freshening properties are
renewed by simply soaking and leaving it to dry in the
sun, the air purifier can be used continuously over a long
time.
Cigarette smoke and toxins found in smoke, such as
carbon monoxide, cannot be removed with this filter.

Room temperature may rise 2-4°C during operation
The dehumidifier does not have a cooler function. Due to heat produced during operation, the room temperature
may rise 2-4°C. As a result, the unit may blow warm air, but this is not due to a malfunction.
How does the dehumidifier work?
If you pour cold water into a cup, the air around it
becomes cold, causing water droplets to form on
the surface of the cup.
The dehumidifier takes advantage of this
phenomenon to remove moisture from the air.
1 The unit draws air from the room, cools it with its
cooling coil, causing the moisture to transform
into water droplets.
2 The water droplets fall into the water tank.
3 The dehumidified air is reheated by the
heating coil, and then discharged.
The humidity of the room is thus reduced by
repeating steps 1, 2, and 3.

Dried (warm) air

The humidity reading on the unit
may differ from a hygrometer in
the same room
Even in the same room, temperature and humidity
levels may differ from place to place. If the hygrometer
and the unit are in different parts of the room, the
humidity levels are prone to differ.
Moreover, humidity levels differ between places that
have good and no airflow.
Use the reading on the unit as an estimate.
Low temperature/humidity decreases dehumidifying effects
In winter, the temperature is low and the air is dry, therefore making dehumidifying impossible.
* If temperatures are low, but humidity is high due to snow or rain, operating the unit in LOW TEMP mode will
yield better results than LOW mode.

What are minus ions?
Minus ions are particles in the air that possess a
negative charge. When there are a lot of minus
ions in the air, it is similar to the environment
encountered in a forest and is said to provide
relaxation.

∞ The level of noise emitted from the unit varies according to the angle of the air-flow.
∞ The louvre may stop up to a maximum of 8 seconds to correct its position, after which it will start moving
again.
Information
∞ If the louvre is knocked out of the desired angle, readjust by following the above steps.

Swing speed is automatically controlled to send air to all
corners of the room.
The louvre moves slowly through the
last 30° of the swing, as the time
taken to traverse the rear arc is
shorter than that for the upward arc
when moving at a constant speed.
The swing function is not available.
Adjust the angle manually (from three
possible positions).
When using the low air outlet, do not close
the louvre, as it needs to open slightly to
make directional adjustments.
Depending on the angle of the louvre, some air may blow out of
the low air outlet.

Troubleshooting
¡ For the symptoms listed below, refer to the remedies listed right.
Symptom
The unit blows warm air
Water does not collect in
the water tank (minimal
dehumidifying results)
The unit does not operate
(no air comes out)
The unit stops
Stops after a
short time
Louvre does
not swing
Lights
Cause/Remedy
¡ Dehumidified air passes through heating coils causing it to
warm (this unit is not a cooler). This is not a malfunction.
¡ Check to see if the temperature/humidity is low.
Low room temperature/humidity reduces dehumidifying
effectiveness. Confirm the current humidity reading (in winter,
the air is dry reducing dehumidifying effects to zero). This is
not a malfunction.
¡ Check to see if the power cord is correctly plugged.
➝ Plug the power cord properly into the power socket.
¡ Check to see if anything is blocking the air intake or outlet.
➝ Remove the obstruction.
¡ Check to see if the pre-filter is clogged.
➝ Clean according to the maintenance procedures.
¡ Is the unit operating in LAUNDRY mode?
➝ The unit may stop after a short time depending on the room
temperature/humidity in this mode.
¡ Check to see if the unit is in EASY DEHUMIDIFYING, MILDEW
GUARD, or AUTO.
The unit is automatically controlling the dehumidifier, fan, and standby times.
¡ Check to see if the water tank is full.
➝ Empty the water tank and return it to its original position.
¡ Check to see if the water tank is inserted properly.

¡ This is the sound of the refrigerant.
The sound can be heard while the refrigerant stabilizes after
the unit turns on, changes modes, or stops.
¡ This is the sound of the compressor.
In modes that monitor the humidity level, the compressor operates
intermittently causing the sound to be heard occasionally.
The compressor does not activate after turning the unit off, or
for 3 minutes after plugging the unit into a power socket. (This
is to protect the compressor from damage.)
¡ The heat converter heats rapidly causing an odour. This is not
