To prevent personal injury, injury to others, or property damage, the following precautions must be observed.

WARNING

Indicates a hazard caused by

mishandling that may result in

death or serious injury.

CAUTION

Indicates a hazard caused by

mishandling that may result in

a minor injury or damage to the

home and its contents.

The following categories describe hazards caused by mishandling

and their levels.

Prohibited

Beware of

rotating

device

Do not

disassemble

Do not

use near

water

The meanings of the graphic symbols used in this manual and on the

unit are as follows.

Observe

instructions

WARNING

Do not use a damaged power cord and

plug, or a loose power outlet.

This may cause electric shock, short circuit, or

fire.

Do not damage the power cord and

plug.

Do not unnecessarily bend, pull, twist, or bind the

power cord, place it close to a hot object, place a heavy

object on it, trap it between objects, or modify it.

•If the power cord is damaged, it must be replaced by

the manufacturer, its service agents, or a similarly

qualified person to avoid hazards.

This may cause damage, resulting in fire or electric

shock.

(Also take care that a pet does not bite the power cord.)

Do not repair, disassemble,

or modify the unit.

This may cause fire or electric shock.

For repairs, contact the retail store

where you purchased the product.

Do not put a wire, pole,

or other foreign object or

a finger into an air inlet

or outlet or any other

opening into the unit.

This may cause electric shock or

injury.

Use a 220-240 V AC power outlet.

Using other than a 220-240 V AC power outlet may

cause electric shock, short circuit, or fire.

Remove the power plug before

cleaning. Also, do not remove the

power plug with a wet hand.

This may cause electric shock or injury.

Remove dust from the power plug

regularly.

If dust accumulates, humidity, etc. may cause an

insulation failure, resulting in fire.

If the unit is operating abnormally or

fails, stop using it immediately.

• The unit does not operate when the operation On/

Off switch is turned ON.

• The unit, power cord, or plug is abnormally hot.

• There is an abnormal noise or vibration during

operation.

• There is a burning smell.

• The operating sound is abnormally loud.

• Mounting screws are corroded or loose.

• The earth leakage circuit breaker trips frequently.

• There is another abnormality or failure.

Failure to do so may cause fire, electric shock, or

injury.

Immediately turn OFF the operation On/Off switch and

disconnect the power plug, and then contact the retail

store.

Do not allow flammable gas to be

sucked inside or use the unit where

flammable gas accumulates.

(Factory, beauty salon, etc.)

This may cause fire.

Do not place the unit close to

flammable objects or objects lit with

fire, such as cigarettes or incense

sticks.

This may cause fire.

Do not get on top of or lean against the

unit.

This may cause the unit to topple or fall and cause

injury.

Do not lay the unit horizontally when

removing a filter.

This may cause dust to enter inside, resulting in fire

or electric shock.

Do not use a damaged filter or operate

the unit while a filter is removed.

This may cause dust to enter inside, resulting in fire

or electric shock.

Do not install the unit where water may

be spilt onto it or where there is a lot

of humidity such as in a bathroom.

This may cause electric shock.

Should water or other liquid be spilt onto the unit, stop

operation and remove the power plug, and then contact

the retail store where you purchased the product.

Do not use the unit in a location with the

oily smoke of machine oil or other oil.

This may cause cracking, resulting in electric shock.

Do not wipe the unit with benzene or

thinner or spray insecticide or other

chemicals onto it.

This may cause electric shock, fire, or cracking

and cause injury.

Do not operate the unit when using an

insecticide that produces smoke.

An accumulation of chemical components may be released

from the air outlet and be harmful to your health.

After using an insecticide, ventilate the area sufficiently

prior to operating the unit.

When using the unit in combination

with a combustion appliance, ventilate

the room occasionally.

Carbon monoxide cannot be removed from the air,

so not ventilating the room may cause carbon

monoxide poisoning.

When disconnecting the power plug,

pull it out straight while holding not the

cord but the power plug.

Failure to do so may cause electric shock or a

short circuit resulting in fire.

When the unit will not be used for a

long time, disconnect the power plug.

Failure to do so may cause the insulation to deteriorate,

resulting in fire from a short circuit or an electric

shock.

This air purifier is designed for household use.

Do not use it for commercial use.

Do not block the air

inlets or outlet.

Do not use this unit

instead of an exhaust fan

or exhaust hood (there is

no ventilation function).

Do not insert a finger or

foreign object into the

PM2.5 Sensor.

Do not use the

unit while it is laid

horizontally.

Do not use the unit while

the inlet panel, pre-filter

unit, HEPA filter, activated

charcoal filter, or platinum

catalyst is removed.

This may cause a

malfunction.

This may cause the filter life

to become shorter and cause

deformation, discoloration,

or malfunction.

This may cause a

malfunction.

This may cause a

malfunction. This may cause a malfunction.

Quickly eliminates contamination in the air before it spreads

into your room using a PM2.5 Sensor and Smart Search.

z Smart Search

The louvre moves in 5 stages and automatically

searches for contamination in the air.

z Cleaning Mechanism

The pre-filter automatic cleaning function reduces

deterioration in performance due to clogging with dust.

The dust on the pre-filter is collected into the dust box.

z Platinum Catalyst and Special

Washable Activated Charcoal

Excellent deodorizing is provided by the platinum

catalyst and special washable activated charcoal.

Soaking and washing the activated charcoal reduces

deterioration of the deodorizing performance.

Reduction of Airborne Viruses

* This is the effect on airborne viruses achieved after operation

for 11 minutes in a test space of a 25 m3, and is not the result

of verification in a space that is in actual use. Manual operation

(Turbo) (510 m3/h) <Testing body> Virus Research Center, Sendai

Medical Center, National Hospital Organization <Test method> The

performance evaluation test of the voluntary standard (JEM1467)

issued by The Japan Electrical Manufacturers’ Association was

performed in a 25-m3test space. <Test object> 1 type of airborne

virus <Test result> 99% reduction in 11 minutes

z PM2.5 Sensor

Improved small particle detection speed and accuracy.

It can even detect 0.5-μm particles.

z Large Air Volume

The maximum air volume of 510 m3/h facilitates quick suction of a large

amount of pollen and dust.

z Support for PM2.5

Catches 99%* of particles from 0.1 to 2.5 μm.

Consideration is not given to new particles entering from outdoors due to, for example,

ventilation.

z PM2.5 is a generic term for fine particulate matter of 2.5 μm or less.

z

The removal of fine particulate matter less than 0.1 μm with this air purifier has not been

verified. Also, this air purifier is not capable of removing all harmful substances from the air.

z This is the effect achieved in a 30-m3enclosed space, and is not the result of verification in

a space that is in actual use.

<Test results> 99% eliminated in 20 minutes

z Two-layer HEPA Filter

Comes equipped with a HEPA filter that catches 99.97% of 0.3-μm pollen

and house dust.

Frequently Asked Questions

What will happen if cleaning is

not performed?

If a lot of dust adheres to the HEPA filter,

performance may deteriorate remarkably.

Will all cigarette smoke be removed?

The air purifier can remove nicotine and other particles, but the room needs to be ventilated occasionally

because carbon monoxide (CO), a harmful substance contained in cigarette smoke, cannot be removed.

Furthermore, when a lot of cigarettes are smoked, cigarette odor may be emitted from the unit.

Operation is performed continuously with maximum air

volume.

When smoking cigarettes, cleaning, and making beds

The air volume is changed automatically depending on the

amount of contamination and odor.

Operation is performed continuously with a constant air

volume.

8. Technical Points

Cleaning mechanism

The pre-filter rotates and passes through the dust box

The dirt on the pre-filter is collected with the cleaning brush

and accumulates on the scraper plate.

Pull out

The dust accumulated on the scraper plate may gather together into a long belt-like shape that does not drop into

the dust box. If the dust on the pre-filter is removed, the cleaning mechanism is working properly.
