Long Distance Air Flow
As a result of the horizontal and vertical flaps that move
independently of one another, a greater diversity of air-
flow is available depending upon your needs: direct air
flow in one direction, long-range cooling, broad left-right
airflow, and three-dimensional cooling.
Easy Control thanks to Touch Display Panel
You need not find Remote controller anymore.
It lets you control the temperature and air flow more
easily.
Full HD Filter (MAX60%)
The full high density filter collects up t0 60% of dust and
allergy causing bacteria
Auto shutter
OFF ON
The auto shutter opens and closes smoothly, revealing
the flaps of the air conditioner only when it is turned
on. The auto shutter protects the air conditioner from
unwanted dust particles, making an unattractive air
conditioner cover unnecessary.

NOTE
• Specification may be subject to change without prior notice.
1) Capacities are based on (Equivalent refrigerant piping 5m, Level differences 0m);
- Cooling : Indoor temperature 27°C DB, 19°C WB / Outdoor temperature 35°C DB, 24°C WB
- Heating : Indoor temperature 20°C DB, 15°C WB / Outdoor temperature 7°C DB, 6°C WB
2) Select wire size based on the value of MCA
3) Sound pressure level is obtained in an anechoic room.
- Sound pressure level based on T1 condition (Indoor temperature 27°C DB, 19°C WB / Outdoor
temperature : 35°C DB, 24°C WB)
- Sound pressure level is a relative value, depending on the distance and acoustic environment.
- Sound pressure level may differ depending on operation condition.
- dBA = A-weighted sound pressure level
- Reference acoustic pressure 0 dB = 20uPa
4) Sound power level is an absolute value that a sound source generates.
- dBA = A-weighted sound power level
- Reference power : 1pW
- Measured according to ISO 3741
5) hese products contain R410A which is fluorinated greenhouse gas.
