Getting the most out of your dehumidifier

Combine operating mode and swing louvre function to get optimum results.

Drying laundry indoors

¡Use the dehumidifier in

a small, enclosed room.

¡Direct the louvres at the

laundry.

¡Space laundry to

improve airflow

¡Maintain room

temperature above 16°C with an air
conditioner

• In low temperatures, drying takes about twice as long as
normal. (Drying times will vary depending on the nature of
the laundry and the room temperature.)

• The airflow is strongest to the top right of the unit.

Installing your dehumidifier

Make sure to leave some
space around the unit.

<For use in close proximity to
a wall>

Stop the louvre in the vertical
position. Blowing air at the
wall may cause staining.

Operating noise

Place the unit on top of a mat. This reduces
vibration and noise. It also prevents leaving
depressions on carpets.

∞ Drain the water tank before use ∞ Refrain from opening doors/windows during operation ∞

Things to be aware of

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.

How is mildew growth
suppressed?

Mildew is unable to produce new spores 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”

<Research paper by Dr. K. Abe of the

Environmental Biology Research Center>

Re-heating coil

Cooling coil

Moist air

Compressor

Dried (warm) air

Water tank

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.

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.

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.

Values for HIGH dehumidifying operation

¡ The dehumidification values shown on the graph

were measured at constant temperature and humidity

minutes (for about 5 minutes) causing water
to drain to the tank.

∞ The unit can operate in a room temperature

range of 1-35°C.
If the room temperature exceeds 35°C, the
inside of the unit heats triggering the protection
mechanism, stopping operation. When using
the louvre, point UP.

• If the temperature is below 1°C, the
extracted water is close to freezing disabling
the dehumidifier, and only the blower is
operational.

(without the hassles of calculating humidity levels and timer settings for the amount of laundry)

¡Laundry

The unit operates for 12 hours and automatically switches off.

∞

Empty the water tank before operating the unit. The unit may stop before the clothes are dry due to a full tank.

∞ Do not use in conjunction with OFF Timer mode. The unit may stop before the clothes are dry.
∞ The following conditions prevent clothes from drying well:

Room temperature below 15°C, large volume of laundry; laundry not spaced well; clothes of thick fabric
and spacious room.

∞ When the room temperature is below 5°C, less water evaporates from the clothes, decreasing the

amount of temperature change. Therefore the unit is unable to detect the state of the laundry and
may turn off after 1 hour.

∞ Restart the unit if it turns off before the laundry dries (except when the temperature is below 5°C).

outlet on the back

Feed the
commercially
available hose (ID 15
mm) into the drainage
outlet while keeping
the stopper pressed

5 Replace the tank.

The unit cannot operate without returning the tank.

CAUTION

Do not drain water continuously
if there is a possibility that
temperatures around the hose could
drop below freezing point.

Water inside the hose may freeze and water may leak
from the unit and damage surrounding objects.

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.

Troubleshooting

¡ For the symptoms listed below, refer to the remedies listed right.

Symptom Cause/Remedy

The unit blows warm air

Water does not collect in
the water tank (minimal
dehumidifying results)

The unit does not turn on
(no air comes out)
The unit keeps turning off

The humidity level does
not reach the level set

The hygrometer reading on
the unit differs from other
hygrometers in the room

The louvre does not move
as set

The water tank contains
liquid or white water residue

There is black residue on the
inside of the water tank and lid.

Louvre does
not swing

¡ 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 air filter is clogged.

➝ Clean according to the maintenance procedures.

¡ Check to see if the unit is in FULL AUTO, 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.

➝ 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.

¡ 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.

¡ Hygrometer readings differ from place to place even if in the

same room. Use the unit humidity reading as an estimate.

¡ Press the Swing louvre switch again.

¡ The residue is from final product testing at the factory. It is not

a result of a malfunction.

¡ The residue is from debris in the air.

➝ Clean according to the maintenance procedures.

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.)
