Installation Manual

 WARNING

•  Do not use any refrigerant different from the one speci

fi

 ed for complement or replacement. 

Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which 
may result in a failure or explosion of the product or an injury to your body.

•  Installation work must be requested from the supplying retail dealership or professional 

vendors. Self-installation may cause water leakage, electrical shock, or 

fi

 re as a result of 

improper installation.

• Speci

fi

 ed tools and pipe parts for model R32 are required, and installation work must 

be done in accordance with the manual. HFC type refrigerant R32 has 1.6 Times more 
pressure than that of conventional refrigerant (R22). Use the speci

fi

 ed pipe parts, and 

ensure correct installation, otherwise damage and/or injury may be caused. At the same 
time, water leakage, electrical shock, and 

fi

 re may occur.

•  Be sure to install the unit in a place which can suf

fi

 ciently bear its weight. If the load 

bearing of the unit is not enough, or installation of the unit is improper, the unit may fall 
and result in injury.

•  Electrical work must be performed by a quali

fi

 ed electrical engineer in accordance with 

the code governing such installation work, internal wiring regulations, and the manual. 
A dedicated circuit and the rated voltage must be used. Insuf

fi

 cient power supply or 

improper installation may cause electrical shock or 

fi

 re.

•  Use a cabtyre cable to connect wires in the indoor/outdoor units. Midway connection, 

stranded wire, and single-wire connections are not allowed. Improper connection or 

fi

 xing 

may cause a 

fi

 re.

•  Wiring between the indoor unit and outdoor units must be well shaped so that the cover 

can be 

fi

 rmly placed. Improper cover installation may cause increased heat, 

fi

 re, or 

electrical shock at the terminal area.

•  Be sure to use only approved accessories or the speci

fi

 ed parts. Failure to do so may 

cause the unit to fall, water leakage, 

fi

 re or electrical shock.

•  After the installation work, ensure that there is no leakage of refrigerant gas. If the 

refrigerant gas leaks out of the pipe into the room and is heated by 

fi

 re or something else 

from a fan heater, stove or gas range, it causes generation of poisonous gas.

•  Make sure the equipment is properly earthed. Do not connect the earth wire to a gas pipe, 

water pipe, lightning conductor, or telephone earth wire. Improper earth work may be the 
cause of electrical shock.

•  Do not install the unit where 

fl

 ammable gas may leak. If there is any gas leakage or 

accumulation around the unit, it can cause a 

fi

 re.

•  Do not select a location for installation where there may be excessive water or humidity, 

such as a bathroom. Deterioration of insulation may cause electrical shock or 

fi

 re.
