Troubleshooting  
Before as the special repair center for help, please check the following items of the air  
conditioner  
Symptom  
Hear the sound of  
water flow  
Cause  
The water flow sound when operation starts; during operation and shortly  
after operation stops, in 2-3 minutes shortly after the operation starts,  
sometimes the sound becomes louder. This is the sound of refrigerant flow  
and the draining sound of condensate water.  
In DEHUMIDIFYING,  
no air sent out or cannot  
change the fan speed.  
In DEHUMIDIFYING operation, when the room temperature is 2 C higher  
than the set temperature, despite of the set FAN SPEED the air conditioner  
will operate in LOW FAN SPEED.  
Because the smells generated by wall, carpet, furniture,clothes, cigarette  
and cosmetic, etc. attached on the air conditioner.  
Having peculiar smell  
in the out air  
In order to prevent the oil and refrigerant from resorting in the indoor  
unit, there is refrigerant flow in very short time, so they give out ì Sha,  
Shaî , ì Gulu, Guluî . Additionally, when the other indoor units perform  
HEATING operation, sometimes white vapor appears; when the other  
indoor units perform COOLING operation, cold air appears.  
The stopped indoor unit  
gives out sound, white  
vapor or cold air.  
If there is the following symptom and check they are the following causes,  
please solve them according to the below given methods.

When Troubles Occur  
Before installing, do read this ì Safety precautionsî carefully to guarantee theproper installation.  
The below attentive matters are divided into ì Warningî and ì Noteî two parts. When the wrong  
installation occur, it is very possible death and severe injury and other serious accidents will happen.  
For those items are listed in ì Warningî part. But even the items listed in ì Noteî part can also  
cause serious accidents. Above all,both the two parts are very important contents related to safety,  
so they must be obeyed.  
After finishing the installation work, do test run to verify everything is normal. After that please explain  
the using and maintenance methods to the user. Additionally, give this installation manual and operation  
manual to the user and ask them to keep it properly.  
Warning  
The commissioned repair center shall do the installation work. If you do the installation work by  
yourself, the improper installation will cause water leakage, electric shock fire and other accidents.  
The installation work shall be in line with what the installation manual specified. If installation is not  
proper, water leakage, electric shock, fire and other accidents will occur.  
Install the air conditioner to a place where can definitely stand its weight. The air conditioner can  
not be installed on a nonmetal bracket (such as theft guard net). Places not firm enough will cause  
drop down of unit resulting in body hurt.  
The installation work shall be preventive to typhoon and earthquake. If the installation work is  
not met with the requirements, overturn of the unit will occur resulting in accidents.  
Using the specified cable to do wiring work and connecting firmly and properly. Fix the connecting  
part of the terminals to prevent it from the external force. Improper connection and fixing will cause  
heating and fire etc. accidents.  
Wiring shall be kept in correct shape avoiding extrusion. After installation, the electric box cover and  
the external panel shall not nip the wire. Improper installation will cause heating and fire etc. accidents.  
When setting or moving the air conditioner do not let the air and things alike get into the refrigeration  
system except the specified refrigerant (R22). If air and other things enter, abnormal high pressure  
will occur, which easily cause break and body injuries etc. accidents.  
When installing, do use the accessories or specified parts. If not using the parts specified  
by our company, water leakage, electric shock, fire and refrigerant leakage will occur.  
Do not lead the drain hose to drain where the sulfur gas may be involved. Otherwise,  
the poisonous gas will enter into the indoor.  
During installation, if refrigerant leakage occurs, do the ventilation work immediately.  
As soon as the refrigerant gas meets fire, poisonous gas will be produce.  
After installation, confirm there is no leakage of refrigerant. If the refrigerant gas enters into room  
and meet the air blowing heater, heater or stove etc. fire source, the poisonous gas may be produced.  
Do not install the unit in a place where the combustible gas may be leaked. In any case  
the combustible gas leaks and accumulated around the unit, fire accident will occur.  
The drain hose should be correctly installed according to the installation manual to ensure  
smooth drainage, and take proper heat preservation measure to prevent from dew.  
Improper pipe installation may cause water leakage result in wet the indoor articles.  
Do heat insulation work to the refrigerant gas pipes and liquid pipes to reach the purpose of heat  
preservation. If the heat insulation measure is not sufficient, water generated by condensing dew will  
drip leading to wet the floor and indoor articles.  
Notice  
Do grounding work. Do not connect the grounding wire to gas pipe, tap, lighting rod or  
telephone line. Improper grounding will cause electric shock.  
In some places the creepage breaker shall be installed. If do not install the breaker, electric  
shock may occur.  
After electric installation, power on them to do electric leakage test.
