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 qualified installer(*1) or qualified service person(*1) is allowed to do installation work. Inappropriate
installation may result in water leakage, electric shock or fire.
• Do not use any refrigerant different from the one specifled 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 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.
• Before carrying out the installation, maintenance, repair or removal work, be sure to 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 qualified installer(*1) or qualified service person(*1) is allowed to undertake work at heights using a
stand of 50 cm or more or to remove the front panel of the indoor unit to undertake work.
• Wear protective gloves and safety work clothing during installation, servicing and removal.
• Do not touch the aluminium fin of the unit. You may injure yourself if you do so. If the fin must be touched for
some reason, first put on protective gloves and safety work clothing, and then proceed.
• 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.
• 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 filter 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
while removing the cover and main unit.
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 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.
• 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.
• 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.
• Do not install in a location where flammable gas leaks are possible. If the gas leak and accumulate around the
unit, it may ignite and cause a fire.
• Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure themselves or
receive electric shocks if they poke their fingers or other objects into the indoor unit while the air conditioner is
running.
