• 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 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 if the power is turned
on without first conducting these checks.
• When you have noticed that some kind of trouble (such as when an
error display has appeared, there is a smell of burning, abnormal
sounds are heard, 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, etc.
• After the work has finished, be sure to use an insulation tester set
(500 V Megger) to check the resistance is 1 MΩ 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 you have discovered that 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.
• 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, etc. 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.
