Frequently Asked Questions
Q.
Why is there still condensation on the windows in the morning?
A. The dehumidifier can take a few weeks to reduce the moisture in your home
to an acceptable level. This is best done by setting the unit to High and
leaving it on 24 hours a day. We also recommend the unit be moved from room to
room. After this initial few weeks the unit can then be set to one of the auto
modes 50~70 and this will maintain the Humidity to your desired level. On cold
mornings there may still be a small amount of condensation on the windows.
Q. Can I leave my Dehumidifier turned on 24 hours a day? A. No problem. The unit can to be left running unattended. It will switch off automatically when the tank gets full or the required humidity is reached.

resulting in malfunction. Should you incline the unit accidentally, contact
service number on the last page for advice.
z Do not carry or store the unit horizontally.
This may result in malfunctions. Such malfunctions are NOT covered under
warranty.
Tips on Dehumidification
Drain the water tank before use.
Close the door and windows during operation.
Drying laundry
· Remove water from the laundry. · Pull to remove any wrinkles on the laundry.
· Use swinging louvre to blow air to the
laundry. · Keep enough space between the laundry to
allow air to pass through.
Use the dehumidifier in a small enclosed room.
In winter, drying becomes easier if you also use a heater to raise the room
temperature to approximately 16°C or more.
z Drying times will vary depending on the type of the laundry and the room
temperature. The low temperature may double the drying time of normal
temperature. (Low temperature means approx. 10°C while normal temperature
means above 20°C.)
z The strong airflow is blown from the top right point of the unit.
Installing your dehumidifier
Make sure to leave some space around the unit to ensure good results.
At least 20 cm
At least 50 cm At least 20 cm
At least 20 cm
Operating noise At least 20 cm
Place the unit on top of a mat. This reduces vibration and noise. It also
prevents leaving depressions on carpets.

Before Using the Unit
Features of This Dehumidifier
Room temperature may rise 26°C during operation.
The dehumidifier does not have a cooler function. Due to heat produced during
operation, the room temperature may rise 26°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.)
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 Dehumidified 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.
Cooling Coil
Moist Air 1
Inverter Compressor
Dry (Warm) Air 3 Re-heating Coil
2 Water Tank
Inverter
The inverter is a device that controls the rotational speed of the compressor
motor. When an operation starts immediately or in other situations, strong
dehumidification is performed at a high motor speed. When the humidity becomes
stable, the motor speed is decreased to continue the operation economically.
The unit can operate in a room
temperature range of 535°C.
If the room temperature exceeds 35°C, the unit may operate in blower mode or
increase the airflow. 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. zzIf the temperature is below 5°C, only the blower is
operational to prevent the extracted water freeze.
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.
y are they different?
Dehumidifying capacity (L/day) Wh
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 dehumidifier is greatly reduced as shown in the graph on the
right. Although only a little water collects in the tank, this is not a
malfunction.

Defrosting operation
When the room temperature drops to about 15°C, defrosting operation starts.
The operation runs every 70 minutes. Compressor stops, airflow is delivered
and the melted frost then drips into the water tank.

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.
Approximately 5 cm
Placing the Dehumidifier
z Place the dehumidifier so that its back faces the laundry. Air blows from
the top of the dehumidifier towards the back.
How to Blow Air at Clothes
z Use swinging louvre to send air all over the laundry. P16 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.
Cloudy and rainy days
Days with a lot of pollen and dust in the air
Days you are unable to bring in the laundry during daylight hours
Operating
During the days of high humidity weather, the laundry will take a long time to dry.
Drying the laundry indoor can prevent pollen particles and other dirt from attaching to the laundry.

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.
z This mode does not remove existing mildew,scales and sticky liquids around
the sinkhole.
z When it is used with the OFF TIMER mode,the unit may stop operating before
completing the drying operation.
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.)

Note Information
z The level of noise emitted from the unit varies depending on the air-blowing
direction. z To locate the position, the air outlet may stop up to 8 seconds
and then start operating again. z If the louvre is touched by hand or object,
the louvre angle will change, so readjust the louvre by pressing the louvre
switch. z If air is blown directly onto a wall, the wall may become dirty
because of dust in the air. z This dehumidifier memorizes the swing direction
but not the desired angle at which the louvre was stopped. The next time
you start it, it returns to the default setting (upward).
When drying your shoes, put them in a position slightly higher from the floor
so that the air from the dehumidifier is directed to them.

Continuous Drainage
If a drain is available, the unit can continuously drain water by attaching a commercially available hose (with an internal diameter of 15 mm) to the drain. As the unit does not stop due to the water tank being full, it can be operated for a long period of time without the need to empty the water tank. If there is power outage during operation, once power is restored, the unit resumes in the mode it was operating before power outage.
Items to prepare · Commercially available hose (ID 15 mm)
Long enough to reach the drain from the dehumidifier.
CAUTION
Do not drain water continuously if there is a possibility that temperature
around the hose could drop to freezing point.
Water inside the hose may freeze and prevent the water in the tank from
flowing out. The water may leak from the unit and damage surrounding objects.
When draining water continuously or left unattended for long periods, inspect
the unit every two weeks.
When the filter or hose is clogged with foreign materials or dirt, the
dehumidification operation is disabled and may cause leakage.

Water does not collect in the water tank (minimal dehumidifying results).
The unit does not operate (no air comes out and the louvre does not swing).
The unit stops.
Stops after a short time.
lights.
The unit continues to operate even though it is turned OFF.
The humidity level does not drop to the set level easily.
The hygrometer reading on the unit differs from other hygrometers in the room.
The louvre does not work as set. The louvre remains open when it stops. The
water tank contains liquid or white water residue. There is black residue on
the inside of the water tank and lid.
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. P6
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.
P6
z Check to see whether the power cord is off.
g Plug the power cord fully into the power socket.
P9
z Check to see if anything is blocking the air intake or outlet.
g Remove the obstruction.

z Check to see if operation is being performed in the MILDEW GUARD mode. g This operation ends automatically when the humidity drops
and will stop in 4 hours as minimum.
P12·14
z Check to see if the pre-filter is clogged.
g Clean according to the “Maintenance” procedures.
P21
z Check to see if operation is being performed in the INTELLIGENT LAUNDRY mode. g If the room temperature drops to approximately 5°C or below, the operation will stop in approximately one hour. The reason for this is that if the room temperature is too low, it becomes difficult to remove moisture from the laundry and humidity does not change. P10
z Check to see whether water tank is full. g Empty the water tank and return the water tank to its original position. P19
z Check to see if the water tank is inserted properly.
g Adjust the position of the water tank.

P4
z Check to see if the pre-filter is clogged.
g Clean according to the methods specified in the
“Maintenance” section.
P21
z Operating the unit on a wood board or in a small room is likely to
cause acoustic resonance.
g Placing a soft mat underneath the unit can reduce the acoustic
resonance.
P5
z Sound increases when the compressor starts operation. (Approximately three minutes after turning on the unit, or during ECO AUTO and EASY operation.)
z The volume of the sound differs depending on the louvre angle. P16
z This is the sound of the refrigerant flow. The sound can be heard when the
unit is turned on, during operation, or when operation stops. No sound can be
heard when the refrigerant flow stabilizes.
z This is the sound of the compressor when it starts up. In ECO AUTO and EASY
modes, the compressor operates intermittently, so there is compressor startup
sound. The compressor does not start when the operation ends or until 3
minutes has passed after the unit is turned on. This is to protect the
compressor from damage.
