Operation
• Before opening the front panel 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 qualified installer(*1) or qualified service person(*1) is allowed to remove
the front panel 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 front panel 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(*1) or a qualified service person(*1).
• Do not move or repair any unit by yourself. Since there is high voltage inside the unit, you may get electric
shock when the cover and main unit is removed.
• 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(*1) or a qualified service person(*1) 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(*1) or a qualified service person(*1).
• 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
sufficiently.
Poor ventilation causes oxygen shortage.
• When the air conditioner is used in a closed room, sufficiently ventilate 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.
• Do not insert your finger 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. Confirm the repair details with a qualified
service person(*1) 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 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(*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 qualified 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.
• 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(*1) 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(*1) or a qualified service person(*1) 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(*1) or a qualified service person(*1) 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 trouble.
Relocation
• When the air conditioner is to be relocated, do not relocate it yourself but contact a qualified installer(*1) or a
qualified service person(*1). Failure to relocate the air conditioner properly may result in electric shocks and/
or a fire.
1Precautions for safety
The manufacturer shall not assume any liability for the damage caused by not observing the description of this
manual.
WARNING
General
• Carefully read Owner’s Manual before starting the air conditioner. There are many important things to keep in
mind for daily operation.
• Ask for installation to be performed by the dealer or a professional. Only a qualified installer(*1) is able to
install an air conditioner. If a non-qualified person installs an air conditioner, it may result in problems such as
fire, electric shock, injury, water leakage, noise and vibration.
• Do not use any refrigerant different from the one specified for complement or replacement. Otherwise,
abnormally high pressure may be generated in the refrigeration cycle, which may result in a failure or explosion
of the product or an injury to your body.
• Places where the operation sound of the outdoor unit may cause a disturbance. (Especially at the boundary
line with a neighbour, install the air conditioner while considering the noise.)
Transportation and storage
• To transport the air conditioner, wear shoes with protective toe caps, protective gloves, and other protective
clothing.
• To transport the air conditioner, do not take hold of the bands around the packing carton. You may injure
yourself if the bands should break.
• Before stacking the packing cartons for storage or transportation, heed the precautions written on the packing
cartons. Failure to heed the precautions may cause the stack to collapse.
• The air conditioner must be transported in stable condition. If any part of the product broken, contact your
dealer.
• When the air conditioner must be transported by hand, carry it by two or more people.
Installation
• Only a qualified installer(*1) or qualified service person(*1) is allowed to carry out the electrical work of the air
conditioner. Under no circumstances must this work be done by an unqualified individual since failure to carry
out the work properly may result in electric shocks and/or electrical leaks.
• After the installation work has been completed, have the installer explain about the circuit breaker positions.
In the event that trouble has occurred in the air conditioner, set the circuit breaker to the OFF position, and
contact a qualified service person(*1).
• If the unit is installed in a small room, take appropriate measures to prevent the refrigerant from exceeding the
limit concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you
implement the measures. Accumulation of highly concentrated refrigerant may cause an oxygen deficiency
accident.
• Do not install the air conditioner in a location that may be subject to a risk of exposure to a combustible gas.
If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.
• Use the company-specified products for the separately purchased parts. Use of non-specified products may
result in fire, electric shock, water leakage or other trouble. Have the installation performed by a professional.
• Confirm that earthing is performed correctly.

clogged. In some cases the drain may overflow and
wet the wall or floor. Clean the drain pan before the
cooling season.)
◆Check periodically
• If the unit is used for a long time, parts may
deteriorate and cause malfunction or bad drainage
of dehumidified water depending on the heat,
humidity, or dust.
• In addition to the usual maintenance, it is
recommended that you have the unit checked and
maintained by the dealer where you purchased it.
NOTE
For environmental conservation, it is strongly
recommended that the indoor and outdoor units of
the air conditioner in use be cleaned and maintained
regularly to ensure efficient operation of the air
conditioner.
When the air conditioner is operated for a long time,
periodic maintenance (once a year) is recommended.
Furthermore, regularly check the outdoor unit for rust
and scratches, and remove them or apply rustproof
treatment, if necessary.
As a general rule, when an indoor unit is operated
for 8 hours or more daily, clean the indoor unit and
outdoor unit at least once every 3 months. Ask a
professional for this cleaning / maintenance work.
Such maintenance can extend the life of the product
though it involves the owner’s expense.
Failure to clean the indoor and outdoor units regularly
will result in poor performance, freezing, water
leakage, and even compressor failure.
