Dirty Air
Clean Air
Pet odor and the smell of cigarette smoke are removed by decomposition by weak ozone O3.
Clean Air
Activated charcoal bacteria eliminating & deodorizing filter
Polyphenol filter
(Grapefruit seed extract)
Earth conductor
Plasma filter generates ions and ozone.
Electric pole
Electrostatic filter
Dirty Air
Negatively-charged dust, etc. are attracted to the earth section and are collected by a bacteria eliminating & deodorizing filter.
Plasma air filter mechanism
Washable filter
Restored to the same performance as when new each time it is washed.
Plasma unit
Mounts a plasma air cleaning unit.Minute dust particles are collected by an electrostatic filter and odor is suppressed by decomposition of foul odors by very weak ions. Since a filter with a lower ventilation resistance than in the past is used, high dust collection design simultaneously cleans in the air in the room.
Europe energy saving Rank A achieved

Easy maintenance
Easy maintenance and always clean. Troublesome maintenance has been made easy.
Since the front panel is easy to remove, maintenance is also easy.
Inner drying operation and plasma effect
This model is equipped with an inner drying function. After the power is turned off, the dry operation starts inside the air conditioner. The plasma air cleaning unit eliminates bacteria, deodorizes, and keeps the interior of the air conditioner clean by generating ozone and ions.

Drying operation for approx. fifteen minutes.
Ozone bacteria eliminating operation for approx. fifteen minutes.
“Inner drying operation” and “ozone bacteria eliminating operation” keep the inside of the air conditioner clean at all times. That ’s why air from the air conditioner is always clean and high efficiency is realized.
After operation ends, start approximately 30 minutes speed cleaning operation by merely pressing the COIL DRY button.

TEST RUN button
This button is used when installing the conditioner, and should not be used un­der normal conditions, as it will cause the air conditioner’s thermostat function to op­erate incorrectly.
If this button is pressed during normal op­eration, the unit will switch to test opera­tion mode, and the Indoor Unit’s OPERA­TION Indicator Lamp and TIMER Indicator Lamp will begin to flash simultaneously.
To stop the test operation mode, press the START/STOP button to stop the air condi­tioner.
