PRODUCT INTRODUCTION
Protect Functions
Protect functions can prolong the air conditioner’ s service life and provide more comfortable airflow.
Delay-starting protection for the compressor
The compressor will restart working at least 3 minutes (5 minutes in heating mode) after being turned off to keep the
pressure balance of the cooling system.
Remarks: There will be 1 minute for the compressor to work after the unit is electrified for the first time.
Defrosting
The outdoor heat exchanger may frost if the outdoor temperature is low and humidity is high. In this case,
auto-defrosting has operated for 3~10 minutes. pause indicator will be on, indoor and outdoor fan stop.
Heating overload protection
When the temperature of indoor pipe is too high, air conditioner enters heating overload protection. And indoor fan
speed should be adjusted to a higher gear automatically. Outdoor fan and compressor may be stopped. When indoor
pipe temperature drops to a rated value, air conditioner will exit heating overload protection. Indoor fan motor
resumes to the normal status.
Blowing residual heat function

In the first several minutes of heating operation, PAUSE indicator lights; indoor fan doesn’t run and louver blades
cannot be controlled. About 5 minutes later, air conditioner will blow heat airflow, PAUSE indicator is off.
Freeze-prevention
To prevent indoor heat exchanger freezing in cooling and dehumidification operation, compressor or outdoor fan may
stop running; indoor fan speed will be adjusted to a higher gear automatically.
Dry for enzyme-prevention
Indoor fan motor will go on running for 3 minutes at low fan speed when turned off in cooling mode in order to keep
dry condition inside the unit.
Auto restart
The unit memories the operation mode, air flow setting, temperature setting etc., so that should there be
a power failure when the unit is in operation, it will automatically return the same operating conditions
when the power is restored.
Cooling overload working
In cooling operation, if the temperature of outdoor heat exchanger is too high, indoor fan speed will be adjusted to a
lower gear automatically and compressor may be stopped.
Drip proof
In cooling and dehumidification operation, louver blades can change the position automatically to prevent from
dripping.
UVC TECHNOLOGY
UVC working theory
The UVC band has a short wavelength and high energy. It destroys the molecular structure in the cells of microbial
organisms (bacteria, viruses and other pathogens) in a short time. By destroying the DNA and RNA of the microbes to
prevent their reproduction, it can achieve an efficient and rapid broad-spectrum sterilization effect. The air and the
surface of the object are sterilized and disinfected, making the cells unable to regenerate, so they are widely used in
the sterilization and disinfection of water and air. The data shows that only 30mW/cm2 of UVC ultraviolet radiation
intensity can kill almost 100% of most bacteria in one second. The effect is very significant, and it can be widely used in
the medical and health field. In the field of personal health and household hygiene, ultraviolet light can be used for
disinfection of water glasses and tableware, air purification and sterilization, killing insects, sterilization and
deodorization of shoes and socks, and disinfection of baby bottles.
58℃self-clean
When self-cleaning is on.
a. Frosting: the evaporator temperature drop down sharply, the frost and ice are created.
b. Heating and melting: turbo heating is on to melt the ice and dry the water. During the high temperature 58℃
virus will be killed in this temperature.
c. Drying: the dust is removed and bacteria is sterilized.

Mildew proof
After the cooling or dehumidification mode is turned off, a large amount of water stains still remains in the evaporator
and air duct of the internal unit. To prevent mildew, mold and breeding of germs, the air conditioner will continue to
supply air for 3 minutes to dry residual moisture.
Anti-virus filter
Lysozyme mainly breaks down the β-1,4 glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine in
the cell wall, so that the insoluble mucopolysaccharides in the cell wall are broken down into soluble glycopeptides,
causing the contents of the cell wall to escape. Dissolve bacteria. Lysozyme can also directly bind to negatively charged
viral proteins and form complexes with DNA, RNA, and apoproteins to inactivate viruses.
