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.
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,
combustible dust, etc.), or fi re may be caused.
Avoid where acid, alkaline matter or corrosive gas might be generated, or susceptibility to
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.
A special circuit should be provided, and it must accord with Engineering specifi cation for
electrical equipments and Specifi cation for indoor electrical wiring .
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.
