• 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 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 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 fire.
• 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.
Test run
• Before operating the air conditioner after having completed the work,
check that the electrical control 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 if the power is turned on
without first conducting these checks.
• If there is any kind of trouble (such as an error display has appeared, smell
of burning, abnormal sounds, the air conditioner fails to cool or heat or
water is leaking) has occurred in the air conditioner, do not touch the air
conditioner yourself but set the circuit breaker to the OFF position, and
contact a qualified service person. Take steps to ensure that the power will
not be turned on (by marking "out of service" near the circuit breaker, for
instance) until qualified service person arrives. Continuing to use the air
conditioner in the trouble status may cause mechanical problems to
escalate or result in electric shocks or other trouble.
• After the work has finished, use an insulation tester set (500 V Megger) to
check the resistance is 1 MW or more between the charge section and the
non-charge metal section (Earth section). If the resistance value is low, a
disaster such as a leak or electric shock is caused at user's side.
• Upon completion of the installation work, check for refrigerant leaks and
check the insulation resistance and water drainage. Then conduct a test
run to check that the air conditioner is operating properly.

Explanations given to user
• Upon completion of the installation work, tell the user where the circuit
breaker is located. If the user does not know where the circuit breaker is,
he or she will not be able to turn it off in the event that trouble has occurred
in the air conditioner.
• If the fan grille is damaged, do not approach the outdoor unit but set the
circuit breaker to the OFF position, and contact a qualified service person
(*1) to have the repairs done. Do not set the circuit breaker to the ON
position until the repairs are completed.
Relocation
• Only a qualified installer (*1) or qualified service person (*1) is allowed to
relocate the air conditioner. It is dangerous for the air conditioner to be
relocated by an unqualified individual since a fire, electric shocks, injury,
water leakage, noise and/or vibration may result.
• When carrying out the pump-down work shut down the compressor before
disconnecting the refrigerant pipe. Disconnecting the refrigerant pipe with
the service valve left open and the compressor still operating will cause air
or other gas to be sucked in, raising the pressure inside the refrigeration
cycle to an abnormally high level, and possibly resulting in rupture, injury
or other trouble.
