• 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 quali
fi
ed
service person (*1). Take steps to ensure that the power will not
be turned on (by marking “out of service” near the circuit breaker,
for instance) until quali
fi
ed service person (*1) 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
fi
nished, use an insulation tester set
(500V Megger) to check the resistance is 1 M
Ω
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 quali
fi
ed
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 quali
fi
ed installer (*1) or quali
fi
ed service person (*1) is
allowed to relocate the air conditioner. It is dangerous for the air
conditioner to be relocated by an unquali
fi
ed individual since a
fi
re, 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.
