Precautions for safety

WARNING
General
• Before starting to install the air conditioner, read through the Installation Manual carefully, and follow its instructions to install
the air conditioner. Otherwise, falling down of the unit may occur, or the unit may cause noise, vibration or water leakage.
• Only a qualified installer(*1) or qualified service person(*1) is allowed to do installation work. If installation is carried out by
an unqualified individual, a fire, electric shocks, injury, water leakage, noise and / or vibration may result.
• If using separately sold products, make sure to use Toshiba specified products only. Using unspecified products may cause
fire, electric shock, water leak or other failure.
• Before opening the 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 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 breakers for both the
indoor and outdoor units to the OFF position. Otherwise, electric shock 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 height, put a sign in place so that no-one will approach the work location before proceeding with the work.
Parts or other objects may fall from above, possibly injuring a person below. Also, be sure that workers put on helmets.
• 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. If you find any part of the product broken, contact
your dealer.
• Do not disassemble, modify, repair or move the product yourself. Doing so may cause fire, electric shock, injury or water
leaks. Ask a qualified installer or qualified service person to do any repairs or to move the product.
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 in a location where flammable gas may leaks are possible. If the gas should leak and accumulate around the
unit, it may ignite and cause a fire.
• When transporting the air conditioner, wear shoes with protective toe caps, protective gloves and other protective clothing.
• 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.
• 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.)
Installation
• 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 or other failure.
• The designated bolts (M10) and nuts (M10) 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.
• Install the unit in the prescribed manner for protection against strong wind and earthquake. Incorrect installation may result
in the unit falling down, or other accidents.
• Be sure to fix the screws back which have been removed for installation or other purposes.
