N OTIC E
If it needs to install, move or maintain the air conditioner, please contact dealer
or local service center to conduct it at first. Air conditioner must be installed,
moved or maintained by appointed unit. Otherwise, it may cause serious
damage or personal injury or death.
When refrigerant leaks or requires discharge during installation, maintenance,
or disassembly, it should be handled by certified professionals or otherwise in
compliance with local laws and regulations.

The Refrigerant
WARNING：
To realize the function of the air conditioner unit, a special refrigerant circulates in
the system. The used refrigerant is R32.
The refrigerant is mildly flammable and inodorous. Furthermore, it can lead to explosion
under certain conditions. But the flammability of the refrigerant is very low. It can
be ignited only by fire.
Compared to common refrigerants, R32 is no harm to the ozonosphere.
The influence upon the greenhouse effect is also lower. R32 has got very good
thermodynamic features which lead to a really high energy efficiency.
The units therefore need a less filling.
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacture. Should repair be necessary, contact your nea-
rest authorized Service Centre. Any repairs carried out by unqualified personnel
may be dangerous. The appliance shall be stored in a room without continuously
operating ignition sources. (for example: open flames, an operating gas appliance
or an operating electric heater.) Do not pierce or burn.
For repairs, strictly follow manufacturer’s instructions only.
Be aware that refrigerants may not containan odour. Read specialist’s
manual.
The appliance is using mildly flammable refrigerant R32 and tested to comply with
IEC 60335-2-40. There is no minimum room area requirement for the appliance.
WARNING:Appliance filled with mildly flammable refrigerant R32.
If the refrigerant is leaked and exposed to external ignition source,
there is a risk of fire.
CAUTION:Before use the appliance,read the user's manual first.
CAUTION:Information is available such as the user's manual first.
CAUTION:Before repair the appliance ,read the service manual first.

Maximum heating 27/- 24/18
NOTICE:
●The operating temperature range (outdoor temperature) for Low-temperature
cooling only unit is -15°C~ 48°C; for Low-temperature heat pump unit is
-25°C~ 48°C.

When the unit is conducting cooling under low temperature, the surface of
indoor heat exchanger will be frosted; when the temperature of indoor heat
exchanger is decreased to below 0°C for a period of time, the outdoor unit will
stop operation.
When outdoor temperature is low and humidity is high, after operating for a period
of time, the heat exchanger of outdoor unit will be frosted, which will lower
heating effect. At this time, the unit will start defrosting mode automatically.
1. During defrosting, there might be steam in outdoor unit. It is caused by quick
defrosting and is normal.
2. After defrosting, heating mode will be resumed.
Under “Heating” mode, if indoor heat exchanger doesn’t reach certain tempera-
ture in the following 3 kinds of status, the indoor fan will not be started to
prevent cold air from blowing (about 2 minutes):
1. Heating operation is just started;
2. After auto defrosting operation;
3. Heating under low temperature.
When operating under heating mode or auto heating mode, shut down the unit
if compressor and indoor fan is working, the compressor and outdoor fan will
stop, air guide louver will be rotated to the horizontal location and indoor fan will
be off after operating for a period of time in low speed.
Special function and specification
When it is set “auto light” by remote controller, the air conditioner will automati-
cally adjust the brightness of display and beeper according to the ambient light
intensity. When the air conditioner detects the ambient light intensity is weak, it
will automatically turn off the display, if it is operated by remote controller, the
display will display in low brightness for a short time, and the beeper beeps
slightly; when the air conditioner detects the ambient light intensity is strong
for a period of time, the above mentioned control will be quitted.

Under cooling or heating mode, press “I Sense” button in the
remote controller or use APP in mobile phone to enter into “I Sense air
supply”, after setting I sense, follow, avoid, surround mode, people sensing
device is automatically activated to detect. The air conditioner will automati-
cally detect the body sense temperature and enter into comfortable
temperature quickly. The air conditioner will automatically adjust the angle
of guide louver and angle of air supply.
After setting “absence energy-saving” via mobile APP, people sensing
device will automatically turn on to detect, when it detects that there is no
people in the room, the air conditioner will automatically operate at
energy-saving mode.
Under the following cases, people sensing device may have wrong detec-
tion, which belongs to normal phenomenon:
1. People sensing device detects the location of people and then controls
the air supply direction, there is certain time difference from detecting to
changing the air direction (it cannot instantly detect the moving of people).
2. Under the following cases may influence the detection of people sensing
device and impact the actual using experience.
The following situations may be detected as absence:
①Indoor temperature is higher than 30℃, or the temperature difference
between the people and the environment is relatively small.
②When the people is immobile or barely move.
③When the people is having his back to the people sensing device.
④When the people exposes very few skin to the air.
⑤When the people is shielded by a higher furniture.
⑥When the people covers with thick quilt or wears thick clothes, the device
is not able to detect.
⑦When the indoor unit cannot detect the people below or in the side of
indoor unit.
Under the following cases the device may detect that there is people in the
room:
①During the operation when it turns on or switches mode, the room
temperature is not stable and temperature difference is relatively large in a
short time.
②There are lamp, TV, computer, pet or related heating elements in the
room.
③The door or window is not well closed, and heating or high-temperature
objects can be detected through the door or window.

In order to prevent user from adjusting the air louver manually, when turning off
the air conditioner or after power failure and re-energization, the air louver will
reset (fully open and fully close), it will spends about 50 seconds, which is
normal phenomenon, please do not cut off the power supply when the air louver
has not fully closed.
2. The auto clean process of evaporator will conduct quick cooling or heating,
there might be big noise which is the sound of liquid flow and injection molding
expansion and contraction; the air conditioner might blow cold air or hot wind
and it is normal. Keep the room ventilated during cleaning process to avoid
affecting comfort.
Tip:
Auto clean function can only be started for operation normally under routine
environment temperature. If the dust at home is heavy, we suggest cleaning it
once in a month; if not, just clean it once in 3 months. After starting auto clean,
the user can leave the room; after auto clean, the unit will enter standby mode
automatically.

1. Under the remote controller is off, press “MODE” and “FAN” button at the
same time for 5 seconds to start auto clean function, then the unit will display
