If the supply cord is damaged, it must be replaced
by the manufacturer or its service agent or a
similarly qualified person in order to avoid a
hazard.
The airflow direction can be adjusted appro-
priately. At operating, adjust the vertical airflow
direction by adjusting the louvers of upward/do-
wnward direction. And then, hold two ends of
left and right louver to adjust the horizontal air-
flow.
Louver of left/right directionLouver of upward/
downward direction.

Principle:
Defrosting:
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.
If the unit is running in COOL mode and in low temperature, 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.
℃
Air conditioner absorbs heat from outdoor and transmits to indoor, in this way to increase
room temperature. This is the heat pump heating principle, its heating capacity will be
reduced due to outdoor temperature decrease.
If outdoor temperature becomes very low, please operate with other heating equipments.
When outdoor temperature is low but high humidity, after a long while running, frost will
form on outdoor unit, that will effect the heating effect, at this time, the auto defrosting
function will act, the heat running will stop for 8-10mins.
During the auto defrosting, the fan motors of indoor unit and outdoor unit will stop.
During the defrosting, the indoor indicator flashes, the outdoor unit may emit vapor.
This is due to the defrosting, it isn't malfunction.
After defrosting finished,the heating will recover automatically.

Troubleshooting
CAUTION
Don't attempt to repair the air conditioner by yourself, it can cause an electric shock or
fire. Please check the following items before asking for repair, it can save your time and
money.
Phenomenon Troubleshooting
Not operate immediately when the air
conditioner is restarted.
There's unusual smell blowing from the outlet
after operation is started. The unit has no peculiar smell by itself. If has,
that is due to the smell accumulated in the
ambient.
Solution method: Cleaning the filter.
If problem still has, so need to clean air
conditioner. (Please contact with the authorized
maintenance center.)
Sound of water flow can be heard during
the operation. The air conditioner is started, when it is
running the compressor started or stopped
running, or the unit is stopped, sometimes
there is swoosh or gurgle, the sound is due
to refrigerant flowing they are not malfuncti-
ons.
In COOL mode, sometimes the mist emitted
from the air outlet vent. 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 die away.
Creaking noise can be heard when start or
stop the unit. This is caused by the deformation of plastic
due to the changes of temperature.
