6 General Information
4. Features
4.1 Universal outdoor unit design
Indoor unit with the same capacity can match with the same out door unit.
4.2 High efficiency and ener gy saving.
Thanks to the DC inverter technology and optimized piping system, the EER and COP of whole
series can easily reach A-class.
4.3 Low noise and low starting current.
Thanks to the DC inverter technology, the system can work with low noise, and very small starting
current.
4.4 Intelligent r ef r igerant adjustment technology.
Throttle part is made up of capillary and electronic expansion valve (EXV). The outdoor unit can
output the most accurate capacity in any condition.
4.5 Working in cooling mode under -15℃.
Outdoor unit built-in with low ambient kit, it can control the outdoor unit’s fan and cooling can be
performed throughout the year for computer rooms, banquet halls, etc. Wide operation range
covers outdoor temperatures as low as -15℃ for cooling.
4.6 Indoor & outd oor unit’s power supply is separate.
4.7 All indoor units have network control function.
4.8 All indoor units have Aut o-restart function.

1. Features
1.1. New design, more modern and elegant appearance.
1.2. Convenient installation
--The ceiling type can be easily installed into a
corner of the ceiling even if the c eiling is very narrow
--It is especially useful when installation of an air conditioner in the center of the ceiling is impossible
due to a structure such as one lighti ng.
1.3. Two direction auto swing (ver t i cal & horiz ontal) and wi de angle air flow,
--Air flow directional control minimizes the air resistance and produces wilder air flow to vertical
direction.
--The range of horizontal air discharge is widened which secures wider air flow distribution to provide
more comfortable air cir culation no matter where the unit is set up
1.4. Three level fan speed, more humanism de sign, meets different air-supply requirement.
1.5. Water proof by util i z i ng the absorbing plastic film on water collector
1.6. Easy operation. Auto-restart function, remote control and optional wire control method.
1.7. Low noise level plus compact size
--Shape of the blades has been im pr oved to prevent noise caused by turbulence.
