Operation
• Before opening the intake grille of the indoor unit or service panel
of the outdoor unit, set the circuit breaker to the OFF position.
Failure to set the circuit breaker to the OFF position may result
in electric shocks through contact with the interior parts. Only a
quali
fi
ed installer (*1) or quali
fi
ed service person (*1) is allowed to
remove the intake grille of the indoor unit or service panel of the
outdoor unit and do the work required.
• Inside the air conditioner are high-voltage areas and rotating
parts. Due to the danger of electric shocks or of your
fi
ngers or
physical objects becoming trapped in the rotating parts, do not
remove the intake grille of the indoor unit or service panel of the
outdoor unit. When work involving the removal of these parts is
required, contact a quali
fi
ed installer or a quali
fi
ed service person.
• Do not move or repair any unit by yourself. Since there is high
voltage inside the unit, you may get electric shock when removing
the cover and main unit.
• Use of a stand more than 50 cm high to clean the
fi
lter of the
indoor unit or to carry out other such jobs constitutes working at
heights. Due to the danger of falling off the stand and injuring
yourself while working at heights, this kind of work should not be
done by unquali
fi
ed individuals. When this kind of work must be
carried out, do not do it yourself but ask a quali
fi
ed installer or a
quali
fi
ed service person to do it for you.
• Do not touch the aluminum
fi
n of the outdoor unit. You may injure
yourself if you do so. If the
fi
n must be touched, do not touch
it yourself but contact a quali
fi
ed installer or a quali
fi
ed service
person.
• Do not climb onto or place objects on top of the outdoor unit.
You may fall or the objects may fall off of the outdoor unit and
result in injury.
• Do not place any combustion appliance in a place where it is
directly exposed to the wind of air conditioner, otherwise it may
cause imperfect combustion.
• When the air conditioner is operated with a combustion appliance
in the same place, be careful of ventilation to let fresh air enter the
room. Poor ventilation causes oxygen shortage.
• When the air conditioner is used in a closed room, be careful of
suf
fi
cient ventilation of the room. Poor ventilation causes oxygen
shortage.
• Do not expose your body to cool air directly for a long time and do
not cool yourself excessively. Doing so may result in deteriorated
physical condition and ill health.
• Never insert your
fi
nger or a stick into the air intake or discharge.
Doing so may result injury as the fan is rotating at high speed
inside the unit.
• Consult the shop where you purchased the air conditioner if air
conditioning (cooling and heating) is not performed properly as a
refrigerant leakage may be the cause. Con
fi
rm the repair details
with a quali
fi
ed service person (*1) when the repair includes
additional charging of the refrigerant.
• Be sure to stop running the air conditioner and turn off the breaker
before cleaning. Otherwise, injury may result as the fan is rotating
at high speed inside the unit.
Repairs
• When you have noticed that some kind of trouble (such as when
a check code 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 quali
fi
ed 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 quali
fi
ed 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.
