Operation
• Before opening the intake grille of the indoor 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 qualified
installer or qualified service person 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
fingers 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 qualified
installer or a qualified service person.
• Do not move or repair any unit by yourself. Since there is high voltage inside the unit, you may get electric shock
during removing the cover and main unit.
• Use of a stand more than 50 cm high to clean the filter 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 unqualified individuals. When this kind of work must be carried out, do not do it yourself
but ask a qualified installer or a qualified service person to do it for you.
• Do not touch the aluminum fin of the outdoor unit. You may injure yourself if you do so. If the fin must be touched, do
not touch it yourself but contact a qualified installer or a qualified 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, ventilate the room adequately.
Poor ventilation may causes oxygen shortage.
• When the air conditioner is used in a closed room, ventilate the room. Poor ventilation may 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.
• Do not insert your finger or a stick into the air intake or outlet.
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. Confirm the repair details with a qualified service person when
the repair includes additional charging of the refrigerant.
• 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
• If there is any kind of trouble (such as when 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 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 failure.
• 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.
• If there is a danger of the indoor unit's falling, do not approach the indoor unit but set the circuit breaker to the OFF position,
and contact a qualified installer or a qualified service person to refit the unit. Do not set the circuit breaker to the ON position
until the unit has been refitted.
• If there is a danger of the outdoor unit's toppling over, do not approach the outdoor unit but set the circuit breaker to the
OFF position, and contact a qualified installer or a qualified service person to have the improvements or refitting done. Do
not set the circuit breaker to the ON position until the improvements or refitting is completed.
• Do not customize the unit. Doing so may result in fire, electric shock or other failure.
Relocation
• When the air conditioner is to be relocated, do not relocate it yourself but contact a qualified installer or a qualified service
person. Failure to relocate the air conditioner properly may result in electric shocks and/or a fire.
