Precautions for safety
The manufacturer shall not assume any liability for the damage caused by not observing the description of this
manual.
WARNING
General
• Before starting to install the air conditioner, read through the Installation Manual carefully, and follow its instructions to
install the air conditioner.
• Only a qualifi ed installer (*1) or qualifi ed service person (*1) is allowed to do installation work. Inappropriate installation
may result in water leakage, electric shock or fi re.
• Do not use any refrigerant different from the one specifi ed 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.
• 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 qualifi ed installer (*1) or qualifi 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.
• Before carrying out the installation, maintenance, repair or removal work, set the circuit breaker to the OFF position.
Otherwise, electric shocks may result.
• Place a "Work in progress" sign near the circuit breaker while the installation, maintenance, repair or removal work is
being carried out. There is a danger of electric shocks if the circuit breaker is set to ON by mistake.
• Only a qualifi ed installer (*1) or qualifi ed service person (*1) is allowed to undertake work at heights using a stand of 50
cm or more or to remove the intake grille of the indoor unit to undertake work.
• Wear protective gloves and safety work clothing during installation, servicing and removal.
• Do not touch the aluminium fi n of the unit. You may injure yourself if you do so. If the fi n must be touched for some
reason, fi rst put on protective gloves and safety work clothing, and then proceed.
• Before opening the intake grille, set the circuit breaker to the OFF position. Failure to set the circuit breaker to the OFF
position may result in injury through contact with the rotation parts. Only a qualifi ed installer (*1) or qualifi ed service
person (*1) is allowed to remove the intake grille and do the work required.
• When work is performed at heights, use a ladder which complies with the ISO 14122 standard, and follow the procedure
in the ladder's instructions. Also wear a helmet for use in industry as protective gear to undertake the work.
• Before cleaning the fi lter or other parts of the outdoor unit, set the circuit breaker to OFF without fail, and place a "Work
in progress" sign near the circuit breaker before proceeding with the work.
• Before working at heights, put a sign in place so that no-one will approach the work location, before proceeding with the
work. Parts and other objects may fall from above, possibly injuring a person below. While carrying out the work, wear a
helmet for protection from falling objects.
• The refrigerant used by this air conditioner is the R410A.
• The air conditioner must be transported in stable condition. If any part of the product is broken, contact the dealer.
• When the air conditioner must be transported by hand, carry it by two or more people.
• Do not move or repair any unit by yourself. There is high voltage inside the unit. You may get electric shock when
removing the cover and main unit.
• To transport the air conditioner, wear shoes with additional protective toe caps.
• 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.
Selection of installation location
• When the air conditioner is installed in a small room, provide appropriate measures to ensure that the concentration of
refrigerant leakage occur in the room does not exceed the critical level.
• Do not install in a location where fl ammable gas leaks are possible. If the gas leak and accumulate around the unit, it
may ignite and cause a fi re.
• Install the indoor unit at least 2.5 m above the fl oor level since otherwise the users may injure themselves or receive
electric shocks if they poke their fi ngers or other objects into the indoor unit while the air conditioner is running.
• 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
