• Follow the instructions in the Installation Manual to install the
air conditioner. Failure to follow these instructions may cause
the product to fall down or topple over or give rise to noise,
vibration, water leakage or other trouble.
• Carry out the specifi ed installation work to guard against the
possibility of high winds and earthquake. If the air conditioner is
not installed appropriately, a unit may topple over or fall down,
causing an accident.
• If refrigerant gas has leaked during the installation work,
ventilate the room immediately. If the leaked refrigerant gas
comes in contact with fi re, noxious gas may generate.
• Use forklift to carry in the air conditioner units and use winch or
hoist at installation of them.
• Suction duct length must be longer than 850 mm.
• Helmet must be worn to protect your head from falling objects.
Especially, when you work under an inspection opening, helmet
must be worn to protect your head from falling objects from the
opening.
Refrigerant piping
• Install the refrigerant pipe securely during the installation
work before operating the air conditioner. If the compressor
is operated with the valve open and without refrigerant pipe,
the compressor sucks air and the refrigeration cycles is over
pressurized, which may cause a injury.
• Tighten the fl are nut with a torque wrench in the specifi ed
manner. Excessive tighten of the fl are nut may cause a crack in
the fl are nut after a long period, which may result in refrigerant
leakage.
• After the installation work, confi rm that refrigerant gas does
not leak. If refrigerant gas leaks into the room and fl ows near
a fi re source, such as a cooking range, noxious gas may be
generated.
• When the air conditioner has been installed or relocated,
follow the instructions in the Installation Manual and purge
the air completely so that no gases other than the refrigerant
will be mixed in the refrigerating cycle. Failure to purge the air
completely may cause the air conditioner to malfunction.

• Nitrogen gas must be used for the airtight test.
• The charge hose must be connected in such a way that it is not
slack.
Electrical wiring
• Only a qualifi ed installer(*1) or qualifi ed service person(*1) is
allowed to carry out the electrical work of the air conditioner.
Under no circumstances must this work be done by an
unqualifi ed individual since failure to carry out the work properly
may result in electric shocks and/or electrical leaks.
• To connect the electrical wires, repair the electrical parts
or undertake other electrical jobs, wear gloves to provide
protection for electricians, insulating shoes and clothing to
provide protection from electric shocks. Failure to wear this
protective gear may result in electric shocks.
• Use wiring that meets the specifi cations in the Installation
Manual and the stipulations in the local regulations and laws.
Use of wiring which does not meet the specifi cations may give
rise to electric shocks, electrical leakage, smoking and/or a fi re.
• Connect earth wire. (Grounding work)
Incomplete grounding causes an electric shock.
• Do not connect earth wires to gas pipes, water pipes, and
lightning conductor or telephone earth wires.
• After completing the repair or relocation work, check that the
earth wires are connected properly.
• Install a circuit breaker that meets the specifi cations in the
installation manual and the stipulations in the local regulations
and laws.
• Install the circuit breaker where it can be easily accessed by the
agent.
• When installing the circuit breaker outdoors, install one which is
designed to be used outdoors.
• Under no circumstances the power wire must not be extended.
Connection trouble in the places where the wire is extended
may give rise to smoking and/or a fi re.
• Electrical wiring work shall be conducted according to law and
regulation in the community and installation manual.
Failure to do so may result in electrocution or short circuit.
