Desiccant is a dehumidification method that does
not use coolants. Thus, it helps protect our global
environment. Furthermore, its dehumidifying
capacity does not drop even the room temperature
is low ( see figure below), so it can still achieve
its dehumidifying capacity even on cold winter days.
Explanation
● Desiccant (a material with strong water absorption
ability) absorbs the moisture and then expels dried air.
That moisture is turned into drops of water in the heat
exchanger and is collected in the tank.

Positioning the dehumidifier
When operating
When using the unit near walls or other furniture,
please keep the distance in between as below.
(With bad ventilation, the temperature may rise and
may result in breakdown of the unit.)
Use with louver Closed
Please make sure there is at least 40cm
between the unit and any walls or furniture.
If the appliance is located too close to a wall or
furniture, there will be too little space for the air to
escape and the unit may overheat and result in the
Humidity indicator working incorrectly.
●Room temperature will rise while the
dehumidifier is in operation, but this is normal.
●It is recommended to keep doors and
windows closed while the unit is in operation.
Opening doors and windows can af fect room
temperature and humidity level, it may then take
longer time to dehumidify or dry clothes.
●The indoor odor caused by wall or furniture
in the room will be reproduced in the air outlet.
( see page 24 for information on any smell from
the appliance.)
Heat is emitted while in operation. Varies depending
upon the room size and air flow, this rise can be
from 3 to 8 degrees Celsius. If room temperature
gets too high, set the appliance to Auto mode.
(In this mode, the temp. rise can be reduced.)
( page 13)
●Operation is possible at room
temperatures from 1 to 40 degrees Celsius,
and at a humidity above 20%.
●The dehumidifying capacity is reduced as
the room temperature and humidity fall.
If same room is dehumidified continuously, the
humidity in the room will become low and the
dehumidifying capacity is also reduced.
●Condensation and mold may appear.
Despite the dehumidifier operates, it is possible that
condensation and mold could still appear on a
window facing outside or in areas with poor
ventilation (such as behind furniture).
At a room temperature outside the range of 1 to 40
degrees Celsius, the dehumidifying operation will
stop and only air circulation will occur. Additionally,
when below 20% humidity, the unit will stop all
operation as a protective measure.

Operating the dehumidifier
Note ●"Auto" mode will automatically switch the heater on and off in order to maintain a humidity of
55%. (If humidity is less than 55%, operation will stop.)
●When you press a button to turn the power on or off or switch the operating
mode, the unit will make a clicking sound. However, this is not a malfunction.
●When Auto Dry Clothes mode is activated, Timer cannot be functioned.
●When the unit starts in "Lo"speed mode, the fan will blow at a medium level for the first two
seconds.

Basing on the standard of Japan Electrical Manufacturers' Association (JEMA-HD090), the approximate drying time is 59
minutes. Testing Conditions: Mode: "Dry Clothes", Room Size: "9.72m2", Temperature: 20 degrees Celsius, Humidity: 70%,
Weight of clothes: 2kg (3 t-shirts, 2 shirts, 1 pair of pajamas, 7 underwears, 2 pairs of socks and 3 towels). Actual drying time
will differ depending on environment and usage conditions.

When hanging clothes in dry indoors, the evaporated
humidity becomes
condensation that will be absorbed by carpet or cushion.
When it takes a long time for clothes to dry, the bacteria may be
retained and results in odors. In addition, when drying indoor, the damp
clothes absorbs the odors inside the room. Using dehumidifier can
prevent from these happening, as it dry your clothes quickly.
When hanging clothes to dry naturally indoor, it takes a
long time to dry and results in odors due to the
accumulated bacteria on the clothes.
Before drying your shoes with a dehumidifier, firstly blow them with
"cold air" setting of a hair dryer until no water is dripping. Then, place
them on a hanger and hang them above the dehumidifier. Adjust the
blowing angle so that the dry air is directed onto the shoes.
If your shoes get wet in the rain, use a dehumidifier to
dry them quickly for the next day.
Do not use a dehumidifier on leather
shoes. Doing so may deform and affect
the quality of the leather.
Leather shoes
When the clothes are dried,
quickly take the clothes down.
Take them down without crumpling,
carefully fold them and
put them into closets.
In rainy days, even after drying,
clothes can re-absorb moisture.

Dehumifying Handling Making
good use
Approximate 100 to 300ml of moisture are released from 1kg of
clothes every hour.This is the same as sprinkling about one cup of water
around your room.When hanging clothes in dry indoors, it is important
to use a dehumidifier to quickly remove humidity inside the room.
