• 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
(500V Megger) to check the resistance is 1MΩ 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 to have the repairs done. Do not
set the circuit breaker to the ON position until the repairs are
completed.
• After the installation work, follow the Owner's Manual to explain
to the customer how to use and maintain the unit.
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.
