• 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
(500V 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.
• After the installation work, confirm that refrigerant gas does not leak. If
refrigerant gas leaks into the room and flows near a fire source, such
as a cooking range, noxious gas may be generated.
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 guard 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
reputing, injury, etc.
