Anti-freezing function:
Working principle and special functions for heating
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 out 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.
４
door temperature is low but high humidity, after a long while running,
The climate type of this unit is according to the nameplate.
The external static pressures at which the appliance was tested should be zero Pa.

Notices for use
Anti-cool wind function:
In "Heat" mode, under the following three kinds of state, if indoor heat exchanger doesn't
arrive at certain temp., indoor fan will not act, in order to prevent cool wind blowing(within
2 mins):
1. Heating starts. 2.After Auto Defrost finished. 3.Heating under the low temperature.
The operating temperature range (outdoor temperature) for cooling unit is -7℃~ 43℃；
for cooling and heating unit is -7℃~43℃.

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.

The unit can not run.Has the power been shut down?
Is power plug loosed?
Is the circuit protection device tripped off or not?
Is voltage higher or lower?

Is the TIMER correctly used?
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

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

Troubleshooting
Phenomenon Troubleshooting
Indoor unit cannot deliver air.
Moisture on air outlet vent.If unit is running under the high humidity for
a long time, the moisture will be condensed
on the air outlet grill and drip off.
Immediately stop all operations and plug out, 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 pull out of the plug.
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 vapo-
rized again, restrain temperature rising.
