Features
4. Features
4.1 Universal outdoor unit design
Indoor unit with the same capacity as the outdoor unit can be matched.
4.2 High efficiency and energy 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 refrigerant 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 & outdoor unit’s power supply is separate.
4.7 All indoor units have network control function.
4.8 All indoor units have Auto-restart function.

Features
1. Features
(1) Low operation noise
—Streamline plate ensures quietness
—Creates natural and comfortable environment
(2) Efficient cooling——Equal, fast and wide range cooling
(3) Excellent performance. The optimal evaporator & sufficient airflow volume guarantees the excellent
capacity
(4) The adoption of the most advanced 3- Dimensional Screw fan
—Reduces the air resistance passing through
—Smoothes the air flow
—Makes air speed distribution to the heat exchange uniform
(5) Fresh air makes life healthier and more comfortable.
(6) Drainage pump can take up the condenser water up to 750mm.
(7) Ultra thin machine body for easy installation and maintenance. 24K:230mm.
8

Features
(8) Different color panels to be chosen: White、Gray、Blue、Black
(9) Swing angle of louver
1) Add one more swing motor, one motor drivetwo louvers. Controlling the interspace of each part,
minimizing the angle loss.
2) The swing angle of the first louver are 40~42 degrees and the second louver are 37~38 degrees.
New evaporator and inner configuration design can acquire high heat-exchanger effect.
(10) More strengthening rib design around the panel, preventing the distortion of the panel.
(11) New outlet frame design to make the phenomena of coagulation with great improvement: prevent the
condensing water from damaging the air guide strip.
(12) Adding rib on the panel of fan outlet, which can avoid the air outlet flow directly to people.
(13) 4 speeds available, optional super high fan speed design suitable for large building over 3m high.
(14) Adding digital tube displaying on the display board. LED can display the Error Code to make
malfunction checking easier.

Features
(15) Reserve spaces for air side-outlet, it is available to connect duct pipe hence air supplying from the four
sides to nearby small room..
(16) The connecting pipe and drop height is higher. Max. pipe length up to 50m（refer to ①）, and Max. drop
height up to 30m（refer to ②）.
(17) Optimal design, smaller Control Box, Space saving and convenient for wiring,
Using fire resistance galvanized steel for E-box material. Metal box make the control part more stable and
prevent damaging.
(18) New Panel optional: 360 degree air-outlet.
