Air conditioner absorbs heat from indoors and then transmit it outdoors for discharging,
so that indoor ambient temperature can be decreased.By this principle,its heating capacity
will decrease with the increase of outdoor ambient temperature.
Anti-freezing function:
If the unit is running in COOL mode with low temperature, there will be frost formed
on the heat exchanger, when indoor heat exchanger temperature is decreased below 0
degree, the indoor unit microcomputer will stop compressor and outdoor fan running to
protect the unit.

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.

Is the TIMER correctly used?
Breaking off
Cooling(Heating) efficiency is not good. Is Temp. setting suitable?
Were inlet and outlet vents obstructed?
Is filter dirty?
Are the windows and doors clothed?
Did Fan speed set at low speed?
Is there any heat sources in the room?
Wireless remote control is not available The unit is interfered by abnormal or frequent
functions switchover occasionally the controller
cannot operate. At this time, you need to pull out
of the plug, and reinsert it.
Is it in its receiving range? Or obstructed?
To check the voltage in wireless remote control
inside is charged, otherwise to replace the batteries.
Whether the wireless remote control is damaged.
If water leakage in the room The air humidity is on the high side.
Condensing water over flowed.
The connection position of indoor unit drainage
pipe is loosed.
If water leakage in outdoor unit When the unit is running in COOL mode, the
pipe and connection of pipe would be condensed
due to the water cooled down.
When the unit is running in Auto Defrosting
mode the ice thawed and flowed out.
When the unit is running in HEAT mode, the
water adhered on heat exchanger dripped off.
Noise from indoor unit emitted. The sound of fan or compressor relay is switching
on or off.
When the defrosting is started or stop running,
it will sound. That is due to the refrigerant flowed
to the reverse direction.

Immediately stop all operations and disconnect power
supply, contact the dealer in following situations.
There is harsh sound during operation
The terrible odors emitted during operation
Water is leaking in the room
Air switch or protection switch often breaks
Carelessy splash water or something into unit
There is an abnormal heat in power supply cord
and power plug.
Stop running and disconnect
After-sales service
In HEAT mode, when the temperature of
indoor heat exchanger is very low, that
will stop deliver air in order to prevent cool
air. (Within 2min)
In HEAT mode, when the outdoor temperature
is low or high humidity, there are much frost be
formed on the outdoor heat exchanger, that the
unit will automatically defrost, indoor unit stop
blowing air for 3-12min.
During the defrosting, there is water flowing out
or vapor be produced.
In dehumidifying mode, sometimes indoor
fan will stop, in order to avoid condensing
water be vaporized again, restrain temperature
rising.
