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 qualifi ed 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 suffi ciency 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 fi re may be caused.
Precautions during installation
Location where the air conditioner should not be installed:•
Avoid where infl ammable gas or volatile combustible matter is likely to leak (e.g., gasoline,
Ř
combustible dust, etc.), or fi re 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 with ĐEngineering specifi cation for •
electrical equipmentsđ and ĐSpecifi cation 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 suffi cient current capacity and rated power, and the line may •
not be tightened excessively.
Fix the power line fi rmly so that external force may not be applied to the terminal block.•
If connection or fi xing is unsecured, the generated heat will lead to electric shock or fi re.•
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 infl ammable gas, sulphurous gas, machine oil, etc.
The drainage pipe must be installed according to those specifi ed 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 fi red.
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.
