Features of This Dehumidifier
z Room temperature may rise 2–4°C during operation.
The dehumidier 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.)
z
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 airow.
Use the reading on the unit as an estimate.

How does the dehumidier 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 Dehumidied air is heated by the re-heating coil, and
then blown out.
The humidity of the room is thus reduced by repeating the
above steps.
z The amount of dehumidifying
becomes less in winter.
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 effect of the dehumidier is greatly reduced
as shown in the graph below.
Although only a little water collects in the tank, this is not
a malfunction.
Summer (humidity) Winter (dampness)
Value for HIGH when humidity is 80%
Dehumidifying capacity (L/day)
Room temperature (°C)
z The values shown on the graph were measured at
constant temperature and humidity and do not
reflect values obtained in actual usage conditions.
28
z The unit can operate in a
room temperature range of
5–35°C.
However, if the room temperature exceeds 35°C, the
unit may operate in blower mode or increase the
airow. This is because the temperature within the unit
rises causing the protection mechanism to operate. In
order to lower the internal temperature of the unit, use
the unit with the swing stopped and louvre vertical.
z If the temperature is below 5°C, only the blower is
operational to prevent the extracted water freeze.

Tips on Drying Laundry
Make full use of the laundry drying operation to shorten the laundry drying time.
How to Hang Clothes
z Pull to remove any wrinkles on the laundry.
z Properly space the laundry for better ventilation
(approximately 5 cm between the laundry).
z Hang out the laundry which is difficult to dry to the place
with good ventilation.
The drying time for the thicker parts of the laundry is probably longer.
<The following conditions will cause longer drying time>
z The laundry is of a large volume.
z The room temperature is lower.
When the temperature is low (approximately 10°C), the
drying time is twice as long as that at normal temperature
(approximately 20°C).
z The room is big.
How to Blow Air at Clothes
z Use swinging louvre to send air all over the laundry.
The drying time of the part where the air cannot reach is longer.
z The laundry is of a large volume.
Shift the position of the laundry during drying so that each part
can get the blowing air.
About the Room for Hanging Clothes
z In a small room, it is recommended that the door and
window be closed before dehumidifying.
It is effective not only to dehumidify, but also to dry the laundry
as soon as possible.
z When the room temperature is low such as in winter
Use a heater in combination with the dehumidifier in order to
raise the room temperature to approximately 16°C or more, so
that it is easy to dry the laundry.
Using the unit to dry clothes hung in a room is recommended on days such as the following.
zCloudy and rainy days
During the days of high humidity
weather, the laundry will take a long
time to dry.
z Days with a lot of pollen
and dust in the air
Drying the laundry indoor can
prevent pollen particles and other
dirt from attaching to the laundry.
z Days you are unable
to bring in the laundry
during daylight hours
After sunset, as the outdoor air
becomes cool, the dried laundry will
absorb moisture.

Reducing Growth of Mildew in Bathroom.*-%&8(6"3%
In this mode, the unit can dehumidify the bathroom to remove residual moisture and water drops, thus suppressing
the mildew growth as a means of mildew prevention.
Information
z For better results, do not turn on the room ventilation
fan or open the window or door when the unit is
operating.
z The results may vary depending on the size, floor
and wall materials of the bathroom.
z There may be some residual water drops in the
places that can collect water.
z Mildew growth may still occur due to the fungus type
and conditions of the room.
<e.g.> Under the containers of the bathroom, deeper
inside of closets and behind furniture and
places with bad air flow.
z Places such as inside of the bathtub, under
containers or where the blowing air cannot reach,
cannot be dried.

About MILDEW GUARD mode
The unit continues to operate for about another 4 hours after the
humidity decreases to 50% and then stops automatically. The
operation time varies depending on temperature and humidity and
ranges from approximately 4 hours (approximately 6 hours if the
room temperature is below 20°C) to approximately 12 hours.
How is mildew growth suppressed?
Mildew is unable to produce new spores if it is dried as mycelia. This principle is applied to the
MILDEW GUARD function. (However, the spores have high resistance to dryness.)

Troubleshooting
z For the symptoms listed below, refer to the remedies listed right.
z The unit blows out warm air because dehumidified air passes
through the re-heater. (There is no cooler function.) This is not a
malfunction.
3
The unit blows warm air.
z
Check to see if the temperature/humidity is low.
At first, confirm the current humidity. Low humidity reduces dehumidifying
effectiveness. (In winter, the dry air makes the humidity low, and the
amount of water collected is decreased.) This is not a malfunction.
3
Water does not collect in the water
tank (minimal dehumidifying results).
z Check to see if the unit is in DRYING INSIDE operation.
The unit starts DRYING INSIDE operation automatically after
ending normal operations.
19
The unit continues to operate
even though it is turned OFF.
z Check to see if the room is too large.
o Use the unit for the specified area range.
28
z Check to see if the windows and doors are opened too often.
o Try to keep the room closed during operation.
z Check to see if steam producing appliances such as kerosene
heaters are on in the vicinity.
The humidity level does not
drop to the set level easily.
z Hygrometer readings differ from place to place even if in the
same room. Use the unit humidity reading as an estimate.
