Plasmacluster ions (a large
quantity of plus and minus ions)
attach themselves to the
surface of floating mold spores.
The hydroxyl radical OH extracts
the hydrogen atom (H) from the
cell walls of the floating mold
spores, thus destroying the cell
walls.
Mold spores
with destroyed
cell walls
self-destroy.
The plasmacluster ions, composed of
plus ions (hydroger ions: H+) and
minus ions (oxygen ions: O2
-
), react
at the surface of floating mold spores
and change to highly active hydroxyl
radical OH.
Plasmacluster ions deactivate floating mold spores
・ Measuring method: In PLASMACLUSTER ION operation, the density of mold spores floating
in the air is measured by an air sampler.
Testing organization: Ishikawa Prefecture Preventive Medicine Organization
Disinfection method: Discharge of plasmacluster ions into the air.
Plasmacluster ions surround the mold spores floating in the room air and inactivate them.
This reduces the odor generated when mold propagates.
PLASMACLUSTER ION effect
Automatically maintain the room humidity in the range 55% to 60%.
For the rooms on the north side or store rooms where people are normally not present.
For drying carpet.
For drying the insides of cupboards and closets. (Open the closet door to dry out the closet)

This dehumidifier is for home use. If you use it with continuous drainage, make sure to check the unit at least once every 2 weeks for
a dirty filter or clogged drain hose.
If you are using a drain hose, make sure that the temperature around the hose does not drop below 0¡C. Water in the hose might
freeze causing water to spill and wet the floor and the unit.
Cover the end of the hose with netting to prevent insects from entering.
The AUTO OFF function also works during CONTINUOUS DRAINAGE. 12 hours after the start of operation, the unit will automatically
stop. The AUTO OFF function can be canceled as described below.
Cautions when using the unit with continuous drainage
Drain hose hole
CONTINUOUS DRAINAGE is possible, if there is a place to drain water nearby. Make sure to stop
operation, disconnect the power plug from the wall outlet and carry out the following procedure.
Open a drain hose hole.
Canceling the AUTO OFF function
Remove the water tank. Using a screwdriver, punch a hole at the drain hose hole
located at the back of the unit. Smoothen the edge of the hole with a file etc.
Before using CONTINUOUS DRAINAGE
Insert the elbow joint into the drainage outlet of the unit.
Remove the drainage tank. Pull down the drain stopper located at the upper right inside the casing.
Put your finger behind the rubber packing on the drain stopper. Then pull the rubber packing off toward
the front and remove the drain seat at the same time.
* These are important parts you will need when not using CONTINUOUS DRAINAGE. Keep the rubber packing and drain seat in a safe place.
Attach the elbow joint to the other end of the hose inserted into the continuous drainage hole.
Insert the elbow joint into the drainage outlet of the unit all the way to the joint base.
* Before inserting the hose into the
continuous drainage hole, remove
the rubber packing and drain seat.
Pull the joint elbow toward you and pull it out of the continuous drainage hole together with the hose.

A clogged filter will result in reduced dehumidification efficiency and higher power
consumption. It can also cause odor.
If you operate the unit without the filter, dust will accumulate in the unit, which may result in malfunction.
Main body
Wipe off any dirt from the unit using a piece of soft cloth soaked in warm water (40¡C max.) or with detergent.
(About once a month)
If detergent is used, make sure to wipe off the detergent with a damp cloth.
The air intake and outlet become dirty easily, so make sure to clean them well.
If water is allowed to splash on the unit, electrical insulation may be affected and corrosion of the unit may eventually result.
Use a neutral detergent (e.g. for dish washing) for cleaning.
Do not use the following types of cleaning agents as they will damage plastic parts.
Thinners, benzine, alcohol, petrol, powder soap, powder polish, alkaline washing agents, hot water, acid or scrubbing brushes.
Do not scrub or expose the unit to chemically treated cloths for any prolonged period of time as this may damage the surface of the unit.
Caution
Maintenance
For safety purposes, turn off and unplug the unit
before carrying out any maintenance.
For clean, sanitary and pro-long use, regular
maintenance is recommended.
E-16
Power supply
cord
Band
Empty the water tank completely.
Wind the power supply cord around the clamp on the rear panel.
If the unit is not used for a long time
Storage
Dry the unit thoroughly and cover with a sheet for dust protection. Store the unit in a well ventilated
place that is not exposed to direct sunlight. If the unit is left uncovered without any protection, dust
will accumulate so that the air emitted by the unit will be dusty next time the dehumidifier is used.

If the filter is very dirty, wash it with neutral detergent diluted in
warm water. Rinse it off and let it dry well in the shade.

Dehumidifying operation increases room temperature.
(The dehumidifier does not have a cooling function.)
The unit generates heat during operation and will become warm. It will blow out warm air, but this is
normal and does not indicate a problem with the unit.
Defrosting
Dehumidification capacity will vary
based on room temperature and
humidity.
The temperature at which the unit can be operated is 5¡C to 35¡C.
If the room temperature is over 35¡C, the built-in protection system will automatically turn off the unit.
Follow the steps below to disable the tank full alarm:
(Operation stopped by AUTO OFF function)
To return to the previous condition, either carry out the procedure described
in again or disconnect the power plug from the wall outlet and plug it in
again to cancel the setting.
Wait for 3 minutes before restarting the unit
Canceling the beeps indicating FULL TANK and
OFF TIMER end
If the unit is turned off, wait for at least 3 minutes before restarting operation.
If the unit is restarted immediately, the compressor will wait for 3 minutes to start up as part of the unitÕs
self-protection system.
Plug the power plug into the socket.
When the PLASMACLUSTER and WIDE SWING buttons are pressed
simultaneously during operation stop for at least 3 seconds, the setting
beep sounds.
Press the POWER ON/OFF button and remove the drain tank. If the
beep does not sound, the setting is completed.
Dehumidification capacity will increase as
temperature rises (as shown in the chart
on the right).
In winter when the room temperature is
low (below 10¡C), use the dehumidifier in
combination with a room heater to reduce
the drying time.
E-17
If the room temperature is below 16¡C, frost may form on the cooling device of the dehumidifier,
and the automatic defrosting function will automatically switch on.
During defrosting, air flow is stopped and the sound of operation will change.
The length of time that defrosting will operate will vary according to room temperature and humidity, but
will be carried out about 5 minutes at 45 minute intervals. (The duration of a defrost cycle will be longer
when the temperature is lower.)
