• 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.
• 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 be generated.
Electrical wiring
• Only a qualifi ed installer or qualifi ed service person 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.
• When connecting the electrical wires, repairing the electrical
parts or undertaking 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.
• When executing address setting, test run, or troubleshooting
through the checking window on the electrical control box, put on
insulated heat-proof gloves, insulated shoes and other clothing
to provide protection from electric shock. Otherwise you may
receive an electric shock.
• 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.
• Check that the product is properly earthed. (grounding work)
Incomplete earthing may cause electric shock.
• Do not connect the earth line to a gas pipe, water pipe, lightning
conductor, or a telephone earth line.
• After completing the repair or relocation work, check that the
ground wires are connected properly.
• Install a circuit breaker that meets the specifi cations in the
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 cable must not be extended.
Connection trouble in the places where the cable 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.
• Do not supply power from the power terminal block equipped on
the outdoor unit to another outdoor unit. Capacity overfl ow may
occur on the terminal block and may result in fi re.
• When carrying out electric connection, use the wire specifi ed in
the Installation Manual and connect and fi x the wires securely to
prevent them applying external force to the terminals. Improper
connection or fi xing may result in fi re.
