PRECAUTIONS FOR SAFETY
WARNING
General
• Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its instructions to install
the air conditioner.
• Only a qualified installer(*1) or qualified service person(*1) is allowed to install the air conditioner. If the air conditioner is
installed by an unqualified individual, a fire, electric shocks, injury, water leakage, noise and/or vibration may result.
• 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 qualified installer(*1) or qualified 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, 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 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 fin of the outdoor 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 working 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.
• When 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.
• When 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.
• The refrigerant used by this air conditioner is the R410A.
• You shall ensure that the air conditioner is transported in stable condition.
• 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.
Selection of installation location
• If you install the unit 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.
• When transporting the air conditioner, wear shoes with additional protective toe caps.
• When transporting the air conditioner, do not take hold of the bands around the packing carton. You may injure yourself if
the bands should break.
• 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.
• 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.
Installation
• When the indoor unit is to be suspended, the designated hanging bolts (M10 or W3/8) and nuts (M10 or W3/8) must be used.
• Install the air conditioner at enough strong places to withstand the weight of the unit. If the strength is not enough, the unit
may fall down resulting in injury.
• Follow the instructions in the Installation Manual to install the air conditioner. Failure to follow these instructions may cause
the product to fall down or topple over or give rise to noise, vibration, water leakage, etc.
• The designated bolts (M10, M12) and nuts (M10, M12) for securing the outdoor unit must be used when installing the unit.
• Install the outdoor unit property in a location that is durable enough to support the weight of the outdoor unit. Insufficient
durability may cause the outdoor unit to fall, which may result in injury.
