Compact Design and Easy Installation
Only about 269mm height in the ceiling is sufficient for
installation space.
A smaller size than a Textile(600X600) is very convenient for installation.
Low Noise with 3-dimensional
turbo fan
The most advanced low-noise design.
The adoption of turbo-fan and round type heat
exchanger provides the quietest operation.
Hygienic and Easy-to-Clean Filter
Washable and anti bacteria filter is adopted.
It is easy to open grille and replace clean filter.

Plasma Air Purifying System
The PLASMA Air Purifying Function not only removes microscopic contaminants and dust, but also removes house
mites, pollen, and pet fur helps to prevent allergic diseases
like asthma.
High Head Drain Pump(700mm)
Built-in Drain Pump drains out water automatically.
A standard drain-head height of up to 700 mm is possible, creating the ideal solution for perfect water drainage.
High-Ceiling Corresponding Operation
According to the height of the installation, it provides variability of indoor fan motor rpm. If the height of installation is
low then you can adjust low rpm of indoor fan motor. On
the other hand if the height of the installation is high you
can adjust high rpm of indoor fan motor. Selection of
speed can be done by slide switch at the back of the LCD
wired remote.
Tele Control (Accessory)
- It provides you ease of control. Air conditioner
can be switched on/off by the telephone. It
saves time & energy.

Child Lock Function
-It prevents the children or others from tampering
with the control buttons. Unit can be controlled by
the wireless remote controller. This can be easily set
by pressing timer key & Min key simultaneously.
After child lock is set, pressing any key will display
CL on the LCD for 3 seconds and all the keys will be
ineffective.
Auto Elevation Grille(Accessory)
-Auto Elevation Grille is automatically down to height
of max. 3.1 m. So it enables to install the Indoor unit
at high ceiling space. And Auto Elevation Grille
makes you cleaning the filter easily.

Swirl Swing
- It is the function for comfort cooling/heating operation.
- The diagonal two louvers are opened the
more larger than the other louvers.
After one minute, it is opposite.
Space Control
Vanes angle can be controlled by pair, considering its
installation environment.
- For example direct drafts can be annoying, leading
to discomfort and reduced productivity vane control
helps to eliminate this problem.
- Easily controlled by wired remote control.
- Air Flow can be controlled easily regarding any
space environment.

Weekly Program
- On/Off schedule of operation for a period of ONE
week.
No need to turn the unit On/OFF manually during
working days. On/Off time is scheduled in micom of
the wired remote control.
Auto Restart Operation
- Whenever there is electricity failure to the unit, and after resumption of the power, unit will start in the same
mode prior to the power failure. Memorized condition are on / off condition, operating mode (cooling/heating),
set temperature and fan speed.The unit will memorize the above conditions and start with same memorized
condition.
Two Thermistor Control
- There may be a significant difference between the temperature taken at the installed product and indoor temperature. Two thermistor control provides option to control temperature by referring any of the two temperatures. With the help of the slide switch at the back of the LCD wired remote controller, selection of the desired
thermistor for controlling the unit can be done. One thermistor is in the Indoor unit & the other one is in the
LCD wired remote.
Group Control
- It enables to control as much as 16 units with the
help of one wired remote controller. All the units will
follow same setting of temperature & other sub functions.
Central Control(Accessory)
- It enables to control 16 x 8 = 128 units with the help
of 8 controllers. All units can be put on and off from
one Central Room.For Setting Temperature, Fan
Speed and other sub functions, access the respective LCD wired remote controller of each unit.
❈ Sub PI485(with wire assembly) should be pur-
chased as optional.
