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. Otherwise, falling down of the unit may occur, or the unit may cause noise, vibration or water leakage.
• Only a qualified installer or qualified service person 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.
• 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.
• 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 or
qualified service person 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 or qualified service person is allowed to undertake work at heights using a stand of 50 cm or more.
• When working at heights, use a ladder which complies with the ISO 14122 standard, and follow the procedure in the ladders
instructions. Also wear a helmet for use in industry as protective gear to undertake the 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.
• 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 modify the products. Do not also disassemble or modify the parts. It may cause a fire, electric shock or injury.
• Before starting to repair the air conditioner, read carefully through the Service Manual, and repair the air conditioner by
following its instructions.
• Only qualified service person is allowed to repair the air conditioner. Repair of the air conditioner by unqualified person may
give rise to a fire, electric shocks, injury, water leaks and/or other problem.
• Once the repair work has been completed, check for refrigerant leaks, and check the insulation resistance and water
drainage. Then perform a trial run to check that the air conditioner is running properly.
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.
• 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.)
• When transporting the air conditioner, use a forklift and when moving the air conditioner by hand, move the unit with
4
people.
