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.

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

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.

This kit allows to operate the air conditioner, such as stopping and starting, using an external
device, and output the operation status of the air conditioner.

• Only operation and stop signals will be output.
Use the remote control to check the operation mode, temperature, and airflow.
Check the error information on the display area of the main unit.

• Operation mode, temperature, and airflow cannot be set by external input. Use the remote
controller to set.

• If the air-conditioner is activated by external input, it will operate in the settings before stop.
To change the settings, use the remote controller.

11-2-1. CONTROL INPUT SETTING

• You can control air conditioner ON / OFF operation by external input.
