The washable photocatalytic filter has a two-layer
construction consisting of a white particle filter and a blue
air-freshener filter.
<Particle filter>
The fine particle filter removes pollen* and dust particles.
<Air-freshener Filter>
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.
* Diameter of pollen: approx. 10-100µm

How is mildew
growth suppressed?
Mildew is unable to produce new spores (similar to plant seeds) if dried as
mycelia. The Mildew Guard feature applies this principle (However, the
spores themselves are resilient to dry conditions.). “Identification of Aspergillus
and Penicillium”

5. Technical points
5.1 The technical points of the new products
1) Drying inside
During dehumidification, moisture accumulates on the heat exchanger. If left, this can lead to mildew
growth, which is circulated around the room with the air discharge. Drying inside starts automatically after
operation, and dries any moisture inside the unit.
2) Powerful 16-litre/day dehumidifying
The uncomfortable damp feeling caused by humidity is something that needs to be removed quickly.
Mildew can grow and damage the home or clothing when closets, dressing rooms, shoe cabinets, and
other spaces where humidity is prone to collect are not dehumidified. A single high-capacity unit is
effective in dehumidifying and drying various locations throughout the home, quickly moving from one
point to the next.
3) Room humidity and sensible temperature comfortably controlled
The EASY DEHUMIDIFYING mode controls humidity according to room temperature. If the room
temperature rises during dehumidification, use CIRCULATION mode (*1) to lower the sensible
temperature.
*1 The automatic dehumidification and blower modes operate alternately controlling the sensible
temperature and humidity to a comfortable level (50%–60%).
4) Washable photocatalytic filter
The photocatalytic deodoring filter and particle filter are integrated.
This filter collects ammonia, the base for household smells, as well as dust, fungus spores, and pollen.
It is easy to clean, meaning longer lasting performance.

5.2 Operation and Performance
Working temperature
Defrosting
Dehumidification is possible with a room
temperature of 1 – 35°C. If the room temperature
exceeds 35°C, however, the temperature inside the
unit will increase; therefore, the protective device
may activate and halt operation in some cases. For
this reason, the louvres should be aimed upward.
• If the room temperature is lower than 1˚C, there is
danger of the removed water freezing, making
dehumidification impossible, so the fan will start
operating.
The unit may display
during operation and stop air
flow, followed by a change in the operating noise. The
unit has stopped the airflow, and is melting internal frost
into the water tank. The unit will resume automatically
when the defrost operation completes.
Wait for 3 minutes before dehumidifying
Room temperature may rise 2-4°C during operation
The dehumidifier will not operate for 3 minutes
when the unit is turned on immediately after being
turned off or plugged in. (In order to protect the
compressor.)
When dehumidifying begins, the operational noise
increases. This is not a malfunction.
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.
During winter, the air may not feel warm as the
temperature is below body temperature.
This operation will be performed automatically when
the room temperature is approximately 15°C or
lower. (When humidity is high, this will occur
approximately once every 40 minutes for 5 – 10
minutes.)
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.

The humidity reading on the unit
may differ from a hygrometer in

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.

5.4 Performance curve
When the temperature and humidity are low, the amount of water collected is
decreased.
In winter, because the temperature is lower than in summer, the effects of the dehumidifier decrease
dramatically as shown in the graph below.
Although less water collects in the tank, this is not a malfunction.
* If the temperature is low, but the humidity is high due to snow or rain, operating the unit in LOW TEMP
mode will yield better results than in LOW mode.

items
If a drain is available, the unit can continuously drain excess water by attaching a commercially available hose
(internal diameter 15mm).
The unit can be operated for extensive periods without the need to empty the water tank.
CAUTION
¡Commercially available hose (ID 15mm)
Long enough to reach the drain.
Do not drain water continuously if there is
a possibility that temperatures around the
hose could drop below freezing point.
¡Pincers
How to set up the drainage hose
Correctly installed
1
Water inside the hose may freeze and water may leak
from the unit and damage surrounding objects.
Incorrectly ¡ hose immersed in
installed
water
¡ hose raised to a
level higher than
the drainage outlet
/ The water will not
drain.
Remove the water tank.
When draining water continuously or left
unattended for long periods, inspect the
unit once a fortnight.
Foreign objects, etc. could clog the hose
resulting in overheating and/or leakage.

11. Troubleshooting
Symptom
Cause/Remedy
The unit blows warm air
¡ Dehumidified air passes through heating coils causing it to warm
(this unit is not a cooler). This is not a malfunction.
Water does not collect in
the water tank (minimal
dehumidifying results)
¡ 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 the amount of water collected). This is not a
malfunction.
The unit does not operate
(no air comes out)
The unit stops
¡ Check to see if the pre-filter is clogged.
➝ Clean according to the maintenance procedures.
Stops after a
short time
¡ Is the unit operating in LAUNDRY mode?
➝ The unit may stop in one hour if the room temperature is about
5°C or less.
Louvre does
not swing
¡ 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.
Lights

¡ 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 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.
➝ Adjust the position of the water tank.
¡ Check to see if the unit is in defrosting mode.
The unit activates defrosting mode when the room temperature
drops below 15°C. The dehumidifier and blower functions stop
during defrosting.
The unit continues to operate
even though it is turned off
¡ Is the unit set to internal drying mode?
This function activates automatically after ending operations.
The humidity level does
not reach the level set
¡ Check to see if the room is not too large.
➝ Use within effective boundaries (floor space).
¡ Check to see if the exits to the room are open.
➝ Refrain from opening doors/windows during operation.
¡ Check to see if steam producing appliances such as kerosene
heaters are on in the vicinity.
The hygrometer reading on
the unit differs from other
hygrometers in the room
¡ Hygrometer readings differ from place to place even if in the
same room. Use the unit humidity reading as an estimate.
The louvre does not move as set
¡ Press the Swing louvre switch again.
The water tank contains
liquid or white water residue
¡ The residue is from final product testing at the factory. It is not a
result of a malfunction.
There is black residue on the
inside of the water tank and lid.
¡ The residue is from debris in the air.
➝ Clean according to the maintenance procedures.
Cause/Remedy
Symptom
The unit
makes
noises
The operating
noise is
loud/reverberates
¡ Check to see if the unit is on a slope or uneven surface.
➝ Move to a sturdy even surface.
¡ Check to see if the pre-filter is clogged.
→ Clean according to the maintenance procedures
¡ Operating the unit in small rooms or in tight spaces sometimes
causes the sound to reverberate.
➝ Place a mat underneath the unit.
The operating
sound suddenly
increases in volume
¡ The sound increases when the compressor activates (3 minutes
after turning on the unit or during Easy dehumidifier and
Automatic modes).
The wind sound
changes in volume
¡ The volume of the sound differs depending on the angle of the louvre.
The unit
produces a
simmering sound
¡ 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.
The unit buzzes
intermittently (or
the compressor
does not
activate)
¡ This is the sound of the compressor.
In modes that monitor the humidity level, or during drying inside 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 unit
produces
an odour
When first
used
¡ The heat converter heats rapidly causing a brief odour. This is not
a malfunction.
During
internal
drying
¡ The moisture expelled from inside the unit may smell due to
odorants* that were not caught by the photocatalytic filter
dissolving in the water. This is not a malfunction.
¡ Error message (Humidity indicator)
