Cautions on Use
Do not operate with the fi lter detached
Otherwise, no cleaning effect can be expected. It
may also cause unit failure.
Do not block or touch the odor and
dust sensors
It may reduce the sensitivity of the sensors.
Do not directly fan plants and animals
It may adversely affect them.
Refrain from moving (changing the orienta-
tion or lifting the unit, etc.) during operation
Moving the unit while in operation may cause the fan
to hit the inner case, generate noise, pull and discon-
nect the power cord, and cause unit failure.
Do not use in locations near cooking appliances
It may cause deformation and dis-
coloration due to heat or oily smoke,
unit damage or fire.
Place the purifier and the cooking appli-
ance at least 1m apart from each other.
Ventilate closed rooms occasionally
The purifier does not have
a ventilation effect (remov-
al of carbon monoxide
and other contaminants).
*
The purifier cannot re-
move harmful substanc-
es in cigarettes (carbon
monoxide, etc.).
Refrain from placing any ob-
ject on the unit and blocking
the air inlet and outlet
Doing so may cause unit failure
and injury.
Do not use near television or radio
Doing so may interfere with
broadcasts.
Please them at least 2m apart
from each other.
The same applies for cord-
less phones and wireless mi-
crophones.
Safety Precautions Cautions on Use Air Cleaner Deodorizing Performance
Air Cleaner Deodorizing Performance
The deodorizing fi lter of the air purifi er does not remove all odors at once, but rather circulates the air in the
room, removing odors gradually.
The deodorizing fi lter is disposable. The deodorizing performance of the fi lter decreases with use.
When the odor emitted from the vent becomes bothersome, soak and wash the deodorizing fi lter.
(P.E-35)
When the deodorizing fi lter has absorbed strong odors or has been continually used in an odorous room,
the odor components remain in the fi lter and unit, causing the odor to be emitted from the vent.
If this happens, you can decrease the amount of odor that remains in the unit by continuing to operate the
purifi er while ventilating the room.
The dust and other contaminants attached to the fi lter and unit also contain odor components.
Periodically clean the fi lter and unit so that odor is less likely to be emitted from the vent.
(P.E-34 - E-36)

Memory Function / Monitor / Sensors / Auto Detection
Auto Detection
The air purifi er performs automatic operation by detecting room air contamination using the “Odor Sensor” and “Dust
Sensor”, and room air temperature and humidity using the “Temperature / Humidity Sensor”.
During the fi rst 3 minutes after the power is turned on, the unit will check the air condition of the room.
The purifi er operates even while it checks the air condition of the room.
During this time, the “Air Sensor” fl ashes green.
After checking the air condition, the “Air Sensor” will display the room air contamination using the “Odor Sensor”
and the “Dust Sensor”.
If you plug in the power cord in an environment containing contaminated air, the sensitivity of the sensor may be
reduced.
To clean the air of the room, operate in “High” or “Max”. Or open a window and unplug the power cord from the AC
outlet when ambient air is clean and plug it back in after 10 minutes.
Vibration Sensor
The sensor detects a fall and impact on the unit. (Installed inside the unit)
The operation may stop due to tilting of the unit, strong vibrations or impact of a collision.

When the Filter Cleaning Indicator Comes On
The indicator lights up approximately 240 hours of performing the humidifying operation after the reset. (Guide for
cleaning)
The humidifying system employed in this product is the evaporating type that produces moisturized air by passing
an air stream through the humidifying fi lter.
Depending on the application environment, dirt or odor may adhere to the humidifying fi lter even when the “Humidify”
or “Skin Moist” mode is not activated. Please clean immediately.
When "Humidify" or "Skin Moist" mode is used, be sure to use tap water for the water tank.
Although the humidifying fi lter has been treated against bacteria and mold, it may get slimy or moldy, or may be-
come discolored to pink, red, green, brown, black or gray after a short period of use depending on the quality of tap
water used, and the application environment. (Discoloration has no effect on humidifying performance.)
It is recommended that the fi lter be cleaned as often as practicable regardless of whether the “Filter Cleaning” indicator lights up or not.
Early replacement of the fi lter is recommended if it exhibits any of the following conditions despite periodic cleaning.
·
Heavy dirt is present, attached hardened water scale is diffi cult to remove, bad odors, serious damage or deformation
If you will not use the “Humidify” or “Skin Moist” mode, dispose any water remaining in the water tray and water
tank. Failure to do so may cause dirt build-up or discoloration.
If you continue to use the humidifying fi lter without cleaning it, the water scale attached to the fi lter will solidify and
possibly come out from the vent.

lukewarm water or water with neutral kitchen
detergent for 30 minutes or longer.
(If there is an unusual amount of dirt, remove
the dirt by rubbing it off with your finger, etc.)
Follow the precautions and usage described on
the neutral kitchen detergent when using it.
(Use only neutral kitchen detergent. )
When using neutral kitchen detergent, rinse the filter so as
not to leave any detergent particles.
CAUTION
Do not remove the humidifying filter from its case.
A magnet is attached to the case in order to detect
the humidifying filter.

leakage during operation.
Also, attach the filter while holding down the unit.
When you use the product for a longer period, white or brown water scales may attach to the inner part
of the water tray or on the surface of the humidifying filter.
Water scales are residue minerals from tap-water that have not evaporated. If you continue to use the
filter without cleaning it, the water scale will come out from the vent in the form of a white powder, or
solidify and become difficult to remove, resulting in lower humidifying performance. In such a case,
replace the filter.
Depending on the quality of tap water used, water scale may attach quickly.
In such a case, clean the filter on a frequent basis.
Rinse the whole case without removing the humidifying filter.
(It might become deformed or damaged if removed. )
Do not deform the humidifying filter by scrubbing it with a brush or using excessive force.
(This will damage it and decrease its performance. )
A new humidifying filter may smell at the beginning. This is normal.
Replace the filter early if it is damaged. (P.E-31)

Replacing the Filter Assembly / Deodorizing Filter
Replacement Interval
The fi lter is disposable. The deodorizing performance of the fi lter decreases with use.
The standard life of a fi lter assembly and a deodorizing fi lter is approximately 10 years as determined by the
Japan Electrical Manufacturers' Association.
A test according to JEM1467(Japan Electrical Manufacturers' Association) was conducted.
If 5 cigarettes are
smoked per day:
[Filter Assembly] Number of years is up to the point the air purifying time takes twice as long as when the fi lter
was new.
[Deodorizing Filter] Number of years is up to the point the deodorizing rate (ammonia, acetaldehyde, and acetic
acid usually contained in tobacco) becomes half as when the fi lter was new.
* This is only a guide. It differs from the actual use in an average household.
The fi lter assembly should be replaced immediately if its color resembles any of the colors on the dirtiness
label attached to the unit.
The colors on the dirtiness label only serve as a guide.
Depending on the installation location, the actual color
of the contaminated fi lter may differ from the color on the label.
Dirtiness Label
For the room seldom
exposed to cigarette
smoke
For the room
always exposed
to cigarette smoke
Filter Replacement Guide
Replace the filter
promptly when its
color becomes
similar to either
color.
Replace the deodorizing fi lter when it becomes diffi cult to remove odor.
Depending on the location and usage, it may also be shortened. If it becomes diffi cult to remove dust or
odor, replace the fi lter immediately. Otherwise, the fi lter may generate odors.
The following cases will shorten the life of the fi lter:
When the purifi er takes in oily smoke, carbon substances (soot), etc. or when the smell of new building materials
remains after the construction or remodeling of a building
When used in stores, such as in coffee shops, game parlors, barber shops, beauty parlors, hotels, inns, and of-
fi ces
When used in places with strong smells such as cigarettes, barbecue, aroma oils, or air fresheners
When the purifi er takes in combustion gases generated by heating appliances
When the purifi er takes in solvents such as paints, adhesives, etc.
When used in dusty locations near roads subject to heavy traffi c.
Handling the Filter Assembly / Deodorizing Filter
Make sure to take the fi lter out of its plastic cover before using.
Do not set the fi lter while it is still inside the plastic cover.
This may cause a unit failure.
Avoid handling it roughly.
Do not crush, crumple, or roll the fi lter.
When the fi lter is broken, it will not have any cleaning effect.
Do not wash the fi lter assembly.
The fi lter assembly cannot be reused even after washing.
Please buy and replace it with a new fi lter assembly.
The fi lter contains plastic. Dispose of the fi lter according to local regulations.

Symptoms Check Solution
The unit does
not humidify
(the humidity
does not in-
crease)
Is the water supply indicator lit? Fill the tank with water.
(P.E-31, E-32)
Is the Filter Cleaning indicator lit?
Refer to “When the Filter Cleaning Indicator
Comes On” in “Cleaning” when cleaning the hu-
midifying fi lter.
(P.E-28 - E-31)
Is the Humidity Monitor displaying 70%?
It automatically operates according to the humid-
ity level.
(P.E-21)
Is the room too large or ventilated?
The humidity may not increase depending on
the size of the room, the installation location,
whether windows are open or closed, and the
state of ventilation. Use the unit in combination
with another humidifi er.
Is a heater used in the room?
Depending on the heater used, the air in the
room may become dry, causing the humidity to
not increase. Use the unit in combination with
another humidifi er.
The humidi-
fying perfor-
mance is inad-
equate
(Water in the
water tank
has not de-
creased)
Is the airfl ow rate weak?
When the “Medium” or “Silent” airfl ow rate is se-
lected, the humidifying performance is lessened.
Set the airfl ow rate to “High” or “Max”.
(P.E-21)
Is there any dust on the pre-fi lter?
Refer to “Pre-fi lter” in “Cleaning” when cleaning
the pre-fi lter.
(P.E-34)
Is the humidifying fi lter correctly set?
Or is it dirty with water scales?
Set the humidifying fi lter correctly.
(P.E-30)
Clean or replace the humidifying fi lter if it is dirty.
(P.E-28 - E-31)
The humidifying performance varies depending
on the level of humidity and temperature of the
room.
If the humidity level is high, such as on a rainy
day, or if the temperature of the room is low, the
humidifying performance decreases.
Humidifying
Following Conditions are Normal
Sounds and Vibrations
Symptoms Cause (This is normal)
When using humidify or skin moisturize
modes, the purifi er sometimes makes whir-
ring and gargling sounds
It is the sound of the unit pumping water from the water tank for a
few seconds every few minutes.
The unit makes rattling sounds when it is
being moved
It is the sound of the metal ball inside the “Vibration Sensor”.
The flap makes whirring, rattling, and rumbling
noises when it is opened, closed, or in swing mode
It is the sound of the motor that moves the fl ap.
The unit vibrates when it is on “Max” airfl ow rate.
It is because of the rotation of the fan.
The airflow rate frequently switches in the
middle of humidify mode and the sound is
distracting
It is because the airflow rate is controlled automatically. When
the humidity changes, the airfl ow rate may switch to “High”.
If it becomes a distraction, switch to your preferred airfl ow rate.
(P.E-21)
The humidifying performance will decrease when it is switched
to a weaker airfl ow rate.
When switching the operation mode or air-
flow rate, the purifier sometimes makes
whirring and whirling sounds
This is the sound of the unit changing the rotational speed of the
motor.

E-42
Heat and Smells
Symptoms Cause (This is normal)
The air coming out of the air outlet smells
The unit’s parts have a smell when it is fi rst used.
Or the deodorizing performance of the deodorizing fi lter has de-
creased.
Clean the deodorizing fi lter.
(P.E-34, E-35)
Or there are odors clinging to the humidifying filter. Clean the
humidifying fi lter.
(P.E-28 - E-31)
The Touch Operation Panel is warm
The unit’s interior is lined with control circuits.
This causes the unit to become warm.
Operations / Others
Symptoms Cause (This is normal)
There is no vapor or mist visible
As the unit employs an evaporating type that produces moistur-
ized air by passing an air stream through the humidifying fi lter, no
vapor or mist is visible.
The movement of the fl ap is unstable, or its
direction is misaligned
It may have become misaligned when it was moved by hand. If it
does not work properly because it was moved by hand, stop it by
pressing the ”Power” button once, and start the operation again.
The temperature and humidity monitor read-
ings differ from the room thermometer and
hygrometer readings.
The temperature and humidity displayed on the monitor is merely
a guide.
Depending on the difference of room environment, the display
may differ.
The fan stopped
The fan may stop
if it is set in eco saving operation.
(P.E-23)
The rotation does not increase smoothly
when “Max” airfl ow rate is used
The rotation gradually increases.
It takes approximately 1 minute for the rotation to increase.
Noise enters the television and radio
Separate the purifi er from the television and radio, or change the
orientation of the purifi er.
Or, use an outlet in a different location.
