
Cold Catalyst Filter:
Eliminate formaldehyde and other volatile organic compounds as well as harmful gases and odors.

Ionizer:
Release negative ions, eliminate odor, dust, smoke and pollen particles to give you fresh and healthy air.

Silver Ion Filter:
Sterilize bacteria effectively by decomposing cell wall of bacteria.

Vitamin C Filter:
Release Vitamin C which can eliminate active oxygen to beautify the skin.

3M HAM Filter:
Open-hole-structure with charged electrostatic effectively capture dust and particles, ensure maximum air
flow and minimum pressure drop.

Bio Filter(O):
Bio filter consists of a specialized biological enzyme and Eco filter. The Eco filter catches very small airborne
dust particles and bacteria, fungi and microbes. Biological enzyme kills bacteria by dissolving their cell wall
thus eliminating the problem of re-pollution.

Golden Fin:
The Golden hydrophilic condenser can improve the heating efficiency by accelerating the defrosting process.
The unique anticorrosive golden coating on the condenser can withstand the salty air, rain and other corrosive
elements.

Self Clean:
When this function is activated, firstly the indoor unit operates as Fan-only mode with low fan speed, during
this period the condensed water will take some dust on evaporator fins away. After that the unit turns to
heating operation with low fan speed which dries the inside of indoor unit. Finally it turns to fan-only mode and
blows away the wet air. The whole process cleans the internal side of indoor unit and prevents the breeding of
bacteria.

Follow me:
With this technology, a temperature sensor is built in the remote control when you stay close to the remote
control, the unit will automatically change the operation mode to supply comfortable temperature just like the
air conditioner is following you.

Louver position memory function:
When starting the unit again after shutting down, its louver will restore to the angle originally set by the user

Refrigerant leakage detect:
The refrigerant leakage detect function can better prevent the compressor being damaged by refrigerant
leakage or compressor overload.

Self-diag.Function:
Monitoring some abnormal operations or parts failures, microcomputer of the air conditioner will switch off and
protect the system automatically.Meanwhile, the error or protection code will be displayed on the indoor unit.

PTC heating belt:
With a PTC heating belt fitted on the base plate of the outdoor unit, the rain, snow or defrosted water
accumulating on the base plate is avoided.

Compressor crankcase heater:
The oil dissolves easily in refrigerant, especially in low temperature condition. The crankcase heating belt can
heat the bottom of the compressor to avoid pumping out too much oil with the refrigerant, which helps to
protect the compressor.

function. And when reaching the setting time,
the timer LED will be off and the running mode
will not be changed.
8.4.7.7 The setting time is relative time.
8.4.9 Auto-Restart function
The indoor unit is equipped with auto-restart
function, which is carried out through an
auto-restart memory module. In case of a
sudden power failure, the module memorizes
the setting conditions before the power failure.
The unit will resume the previous operation
setting (not including swing function)
automatically after 3 minutes when power
returns.
If the auto restart condition occurs in forced
cooling mode, the unit will run in cooling mode
for 30 minutes and turn to auto mode at 24℃
set temp.
If system is off before power goes out it will stay
off. When the unit is started up by the user, the
compressor will have 1 minute delay. For other
conditions, the compressor will have 3 minutes
delay when restarts.
8.4.10 8℃ Heating (Vacation Mode -
8.4.8 Sleep function mode
8.4.8.1 Operation time in sleep mode is 7 hours.
After 7 hours the system quits this mode and
turns off.
8.4.8.2. Operation process in sleep mode is as
follows:
When cooling, the setting temperature rises 1℃
(if room is lower than 30℃) every one hour, 2
hours later the setting temperature stops rising
and indoor fan is fixed as low speed.
Optional)
In heating operation, the preset temperature of
the air conditioner can be as lower as 8℃,
which keeps the room temperature steady at 8℃
and prevents household items from freezing
when the house is unoccupied for a long time in
severe cold weather (Vacation Mode)
