• The designated bolts (M10) and nuts (M10) for securing the outdoor
unit must be used when installing the unit.
• Install the outdoor unit property in a location that is durable enough to
support the weight of the outdoor unit. Insufficient durability may cause
the outdoor unit to fall, which may result in injury.
• If refrigerant gas has leaked during the installation work, ventilate the
room immediately. If the leaked refrigerant gas comes in contact with
fire, noxious gas may be generated.
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 flare nut with a torque wrench in the specified manner.
Excessive tighten of the flare nut may cause a crack in the flare nut
after a long period, which may result in refrigerant leakage.
• 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 qualified installer(*1) or qualified 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 unqualified individual
since failure to carry out the work properly may result in electric shocks
and/or electrical leaks.

• The appliance shall be installed in accordance with national wiring
regulations. Capacity shortages of the power circuit or an incomplete
installation may cause an electric shock or fire.
• Use wiring that meets the specifications in the Installation Manual and
the stipulations in the local regulations and laws. Use of wiring which
does not meet the specifications may give rise to electric shocks,
electrical leakage, smoking and/or a fire.
• Be sure to connect earth wire. (Grounding work)
Incomplete grounding causes an electric shock.
• Do not connect ground wires to gas pipes, water pipes, and lightning
rods or ground wires for telephone wires.
• After completing the repair or relocation work, check that the ground
wires are connected properly.
• Install a circuit breaker that meets the specifications 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 must the power cable be extended.
Connection trouble in the places where the cable is extended may give
rise to smoking and/or a fire.
Test run
• Before operating the air conditioner after having completed the work,
check that the electrical parts box cover of the indoor unit and service
panel of the outdoor unit are closed, and set the circuit breaker to the
ON position. You may receive an electric shock etc. if the power is
turned on without first conducting these checks.
