Outdoor Unit
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
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.
