3 3. Features & Benefits Compact Design and Easy Installation nly about 269mm height in the ceiling is sufficient for installation space. A smaller size than a Textile(600X600) is very convenient for installation. ' (18k Btu/h model) Low Noise with 3dimensional turbo fan The most advanced lownoise design. The adoption of turbofan and round type heat exchanger provides the quietest operation. Sm Hygienic and EasytoClean Filter Washable and anti bacteria filter is adopted. It is easy to open grille and replace clean filter. Energy Saving Gold Fin () Heat Exchanger fins are coated with anticorrosive & hydrophilic layers. It prevents the corrosion of heat exchanger. Fins remain as new even after long time of operation and maintains efficiency of heat exchanger constant. It also saves power & maintenance Cost. Salt Spray Test Result: After 360 hours [ Test Standard: ASTM B117, KS D 9502 ] Tele Control (Accessory) It provides you ease of control. Air conditioner can be switched on/off by the telephone. It saves time & energy. In Advance by Telephone before Coming Home... In case of Going out Without Turning off the Air Conditioner...

4 3. Features & Benefits 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. C a t i l v [Dust electrode discharge stcoatd Mesti doir m* cut High Head Drain Pump (700mm) Builtin Drain Pump drains out water automatically. A standard drainhead height of up to 700 mm is possible, creating the ideal solution for perfect water drainage. Slope 1/501 f\ 00 Hand Tube (ex.pvc) High Ceiling peration: 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. n 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. Ex: Ceiling height Mode of slide svntch Change of air volume Remark more than 3.3m High Ceiling Increasing 2.7~3.3m Standard less than 2.7m Low Ceiling Decreasing Manufactured in standard mode

5 3. Features & Benefits Child Lock Function It prevents the children or others from tampering with the control buttons Unit can be controlled by th e wireless remote controller This can be easily set by pressing timer key & Min key simultaneously After child lock is set. Pressing any key will deplay CL on the LCD for 3 seconds and all the keys will be ineffective Jet Cool: In this mode quick and fast cooling IS done Cold and high velocrh/ air IS supplied to the room till the indoor temperature reaches 18 C Auto Elevation Grillefpttonal) Auto Elevation Grille E automaticalry down to height of max 3. 1 m So it enables to install the Indoor unrt at high ceiling space And Auto Elevation makes you cleaning the filter easiry Swirl Swing it is the function for comfort cool/heating operation The diagonal two louvers are opened the more larger than the other louvers After one minute, rt is opposite Group Control: ft enables to control up to 16 units with the help of one wired remote controller All the units will follow same setting of temperature & other & sub function actions

6 3. Features & Benefits Space Control Vanes angle can be controlled by pair, considering its installation environment For example direct draft can be annoying, leading to discomfort and reduced productivity vane control helps to eliminate the problem Easily controlled by wired remote control Air Flow can be controlled easiry regarding any space environment Auto Changeover: While starting the unit first senses the indoor temperature & start the unit either in the cooling or in heating mode, depending upon the indoor temperature Range of operation IS Setting Temp ±2 n C

7 3. Features & Benefits Time Delay Safety Function: It delays restarting of the compressor by three minutes thereby preventing damage to the compressor Long Refrigerant Piping: L Ceiling Cassette air conditioners can cover up to 50m length and 30 m height It provides flexibility of installation and keep the building in a good outlook Zero Standby Power: Due to SMPS (Switching Modulation Power Supply] technology, there E almost zero power consumption in the standby mode 50m Hot Start Function: During starting of the unit in the heating mode, It prevents cold air to blow out from the unit It starts the indoor fan only after indoor unrt pipe temperature reaches a preset value<2s C] When indoor unit pipe temperature has reached 28 n C. Then for initial 1 minute the indoor fan runs at low speed and after that at the set fan speed Defrost/ Deicing: In the heating mode, it prevents the ice formation on the outdoor unit The heating cycle IS reversed to the cooling cycle to defrost the evaporator pipe of the outdoor unit While defrost cycle, the compressor is on and indoor fan. utdoor fan and 4way valve are off Low Ambient Control: If the outdoor temperature drops below certain temperature, liquid back to the compressor IS prevented by reducing outdoor fan speed It can prevent frosting of evaporator and keep cooling operation on
