Safety instruction
Caution
Please read this installation manual carefully and be sure to comply with the instructions in
this manual before installing and using this unit!
For this product, the following standards apply:
GB/T 18837-2002 JB 8655-1997 GB 4706.1-2005
Preparation before installation
Please have a qualified licensed professional technician handle the installation of this unit. Users•
may not install, repair or displace the air conditioner by themselves;
Please have a licensed professional electrician handle the power wiring, and inspect safety in•
utilizing electricity, such as sufficiency of line capacity, damage of power line, etc.;
Please be sure to install the air conditioning unit according to this manual. In the case of any•
improper installation, water leakage, electric shock or fire may be caused.
Precautions during installation
Location where the air conditioner should not be installed:•
Avoid where inflammable gas or volatile combustible matter is likely to leak (e.g., gasoline,
Ř
combustible dust, etc.), or fire may be caused.
Avoid where acid, alkaline matter or corrosive gas might be generated, or susceptibility to
Ř
corrosion of the unit may be caused, and lead to leakage of refrigerants;
Avoid where dust, steam, oil fume or special spraying agent diffuses, e.g. kitchen, etc.
Ř
A special circuit should be provided, and it must accord withĐEngineering specification for•
electrical equipmentsđandĐSpecification for indoor electrical wiringđ.
The unit must be earthed properly. Be sure to connect the earth wire to the ground reliably. Do•
not connect the earth wire to water or gas pipes, or telephone wire.
Please use the power line having sufficient current capacity and rated power, and the line may•
not be tightened excessively.
Fix the power line firmly so that external force may not be applied to the terminal block.•
If connection or fixing is unsecured, the generated heat will lead to electric shock or fire.•
The electrical parts of the unit shall be damp-proofed, apart from water source. Do not install the•
wired controller where easy to contact the inflammable gas, sulphurous gas, machine oil, etc.
The drainage pipe must be installed according to those specified in this manual to ensure smooth•
draining. Heat insulation should be done to prevent generating condensate water.
If being installed in a relatively small room, relevant measures must be taken to prevent•
concentration of refrigerants in the room exceeding limit value in case of leakage.
During installation, if secondary refrigerants leak, ventilation is required. The leaked refrigerants•
will generate poisonous gas in case of being fired.
After completion of installation, tightness test shall be performed for the pipes. Inspect where air•
leakage exists.
Be sure to use the R410A specialized tools and accessories for the air conditioning unit that•
R410A refrigerants are used.

Safety instruction
Precautions during trial operation
Do not operate the wired controller or remote controller with wet hands. Do not splash water•
into the wired controller or remote controller.
Do not pull or bend the cable of the wired controller. Never use sharp object press the button,•
and avoid improper connection.
During operation of the unit, never extend the finger, stick or rod into the air inlet or outlet.•
In the process of operation or at the just end of operation, never touch the refrigerant piping•
with hands because the terribly hot or cold piping may easily lead to scalding or freezing injury of
hands.
After stopping operation, do not switch off the power immediately, but wait for 5 min at least and•
then turn it off; or else, water leakage might be caused.

Unit installation
Precautions
Be sure to take out the indoor unit from the packing case. When handling the air conditioner,•
please hold the stress area of the air conditioner, such as lifting lug etc., not the steam pipe,
liquid pipe or drainage pipe;
Select the place where a relatively short duct is used, the quantity of connecting work is minor•
and it is convenient to wire and couple the pipe, and connect with indoor unit;
Make sure that the bearing strength of the installation site is enough to undertake the weight of•
the indoor unit; or else, unit damage or personal injury may be caused;
Make sure that the strength of the hoisting screw is sufficient to withstand the weight of the•
unit, and at least 4 ones should be used;
Ensure good ventilation so that the air flow can be blown throughout the room;•
Obstruct should be put away from the air inlet or outlet so that the air may be circulated freely;•
Make sure that there are enough space for service and maintenance. The access door is located•
at the side of the electrical control box so as to be convenient for service and maintenance;
Install the indoor unit at a place where is apart from the lighting facilities using ballasts. When•
operating the wireless remote controller, the ballast can lead to receiving failure;
Keep the indoor unit far from direct sunlight.•
Installation of the concealed indoor unit
Hang the unit up on a firm and horizontal support such as the ceiling. In case that the hoisting1.
surface is not firm, noise, vibration or leakage will be caused. See the following figure.
