DESCRIPTION OF PRODUCTS & FEATURES

1.4Products characteristic
Completely invisible machine body
The whole machine body is completely concealed inside the ceiling. Due to its compact size it neither
breaks the harmonization of indoor decoration nor occupies the indoor spaces. The stylish look of air
conditioner allows it to blend right into ceiling.
Superbly efficient healthy filter
Superbly efficient antibiotic materials are utilized and can prevent germs from breeding efficiently.
Flexible and easy installation
Slim design with machine body, completely ceiling concealing and portable shape, all make it
greatly easier to install. Moreover, it occupies least constructional spaces, which help to reduce
constructional cost prices. It also features a specific drainage system with up to 600mm lift , which
allows reducing installation spaces and ensures to drain smoothly. Thanks to its "smudge-free"
mobile outlet grill, the ceiling can be protected from pollution effectively and allow the airflow to fit
people's comfortable need much more.
Auto-Restart function
When meeting a power failure during running, no matter how long it will be, once the power is
restored, air conditioner will automatic restart with the previous status.
Safety and reliable control due to various signal controls
1 Inputting with press buttons on the panel
2 Inputting with temperature sensors (indoor ambient temperature sensors, indoor coil pipe
temperature sensors, outdoor ambient temperature sensors, outdoor coil pipe temperature
sensors)
3 Piping pressure signals
4 Compressor current signals
5 Testing signals
6 System time-shorten signal
7 Water overflowing signal
8 Communication signals between indoor unit and front plate or between indoor unit and outdoor unit .
Precise convenient remote-controlling
When using remote-controlling mode, it is comfortable and convenient to operate.
Silent design
The use of radial outward flow turbine fan produces larger cyde airflow volume and acts to significantly
decrease operating noise.
HFC refrigerant technology
To protect the environment, we have adopted the HFC refrigerant. The HFC R407C is of aero ODP
for the purpose of environmental protection.
Low ambient temperature cooling technology
The system can run the cooling operation at the low ambient temperature -15
