Working principle and special functions for cooling
Principle:
Air conditioner absorbs heat in the room and transmit to outdoor and discharged,
so that indoor ambient temperature decreased, its cooling capacity will increase
or decrease by outdoor ambient temperature.
Anti-freezing function
If the unit is running in COOL mode and in low termperature, there will be frost formed
on the heat exchanger, when indoor heat exchanger temperature decreased below 0℃,
the indoor unit microcomputer will stop compressor running and protect the unit.
Working principle and special functions for heating
Principle:
The unit absorbs heat from outdoor air, carrys and emits the heat in indoors
to make indoor air temperature higher. Its heating capacity would be lower
according to the low weather of outdoor ambient.
This heating air circulation system can enhance the indoor temperature
in a short while.
If outdoor temperature got lower, please operate with the other heating ventilating
equipments.
Defrosting:
When outdoor temperature is low but with high humidity, after a long while running,
frost will form on outdoor unit, that will affect the heating effect, at this time,
the auto defrosting function will act, the heat running will stop for 8-10mins.
During the auto defrost, the fan motors of indoor unit and outdoor unit will stop.
During the defrost, the indoor indicator flashes, the outdoor unit may emit vapor.
This is due to the defrosting, it isn't malfunction.
After defrost finished,the heating will recover automatically.
Anti-freezing function:
In "HEAT" mode, under the following three states, if indoor heat exchanger didn't reach certain
temperature, indoor fan would not operae to prevent blowing out cool air:
(Within 3mins)
1.Heating starts. 2.Afer Auto defrosting finished. 3.Heating under the low temperature.
The conditions of unit can't normally run
The following temperature range protection device may act, that may cause stop running.

Troubleshooting
CAUTION
Don't attempt to repair the air conditioner by yourself, it can cause electric shock or fire.
Please check the following items before asking for repair, it can save your time and money.
TroubleshootingPhenomenon
Once the air conditioner is stopped, it will
not operate in approximately 3 minutes to
protect itself.
Not operate immediately when the air
conditioner is restarted.
The unit has no peculiar smell by itself. If has,

ambient.
Solution method: Cleaning the filter(refer to P11).
If problem still exist, clean air conditioner.
(please contact with our authorized maintenance
center.)
There's unusual smell blowing from the
outlet after operation is started.
Sound of water flow can be heard during the
operation.
When unit is started, when operating compressor
starts or stops, or when unit is stopped, sometimes
there is swoosh or gurgle sound. This sound is
due to refrigerant flowing, but not malfunctions.
from the air outlet vent.
In COOL mode, sometimes the mist emitted When the indoor temperature and humidity are
very high, this phenomenon would happen. This
is caused by the room air is swiftly cooled down.
After running for a while, indoor temperature and
humidity will fall down, the mist will disappear.
Creaking noise can be heard when starting or
stopping the unit.
This is caused by the deformation of plastic due
to the changes of temperature.

Earthing requirements
Others
The model of the blown fuse and rated value should refer to the silk-screen on the
controller or fuse sleeve.
The connection method of unit and power cable as well as the interconnect method
of each isolated component should refer to the circuit diagram stick on the unit.
Air conditioner is type 1 electric appliance, thus please do conduct reliable earthing
measure.
The yellow-green two-color wire in air conditioner is earthing wire and cannot be used
for other propose. It cannot be cut off and be fixed by screw, otherwise it would cause
electric shock.
The user power must offer the reliable earthing terminal. Please don't connect the
earthing wire with the following place:
①Tap water pipe②Gas pipe ③Contamination pipe
④Other places that professional personnel consider them unreliable.
It should be reliably earthed, and it should be connected to the special earth device,
the installation work should be operated bythe professional.
The air switch must have the functions of magnetic tripping and heat tripping, in order
to protect the short circuit and overloading.
