Outdoor Unit
• Do not use any refrigerant different from the one specifi 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.
• Specifi 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 specifi 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 suffi 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 qualifi 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. Insuffi 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 specifi 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.
