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(*1) or qualified service person(*1) is allowed to do installationwork. 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.
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.
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 (M12) and nuts (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.
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.
Refrigerant piping
Install the refrigerant pipe securely during the installation work before operating the air conditioner. If the compressor is
operated with the valve open and without refrigerant pipe, the compressor sucks air and the refrigeration cycles is over
pressurized, which may cause a injury.
Tighten the flare nut with a torque wrench in the specified manner. Excessive tighten of the flare nut may cause a crack in
the flare nut after a long period, which may result in refrigerant leakage.
Ventilate the air if the refrigerant gas leaks during installation. If the leaked refrigerant gas comes into contact with fire, toxic
gas may be produced.
After the installation work, confirm that refrigerant gas does not leak. If refrigerant gas leaks into the room and flows near a
fire source, such as a cooking range, noxious gas may be generated.
When the air conditioner has been installed or relocated, follow the instructions in the Installation Manual and purge the air
completely so that no gases other than the refrigerant will be mixed in the refrigerating cycle. Failure to purge the air
completely may cause the air conditioner to malfunction.
Nitrogen gas must be used for the airtight test.
The charge hose must be connected in such a way that it is not slack.
If refrigerant gas has leaked during the installation work, ventilate the room immediately. If the leaked refrigerant gas comes
in contact with fire, noxious gas may be generated.
Electrical wiring
Only a qualified installer(*1) or qualified service person(*1) is allowed to carry out the electrical work of the air conditioner.
Under no circumstances must this work be done by an unqualified individual since failure to carry out the work properly may
result in electric shocks and/or electrical leaks.
When connecting the electrical wires, repairing the electrical parts or undertaking other electrical jobs, wear gloves to
provide protection for electricians and from heat, insulating shoes and clothing to provide protection from electric shocks.
Failure to wear this protective gear may result in electric shocks.
When executing address setting, test run, or troubleshooting through the checking window on the electrical control box, put
on insulated heat-proof gloves, insulated shoes and other clothing to provide protection from electric shock. Otherwise you
may receive an electric shock.
Use wiring that meets the specifications in the Installation Manual and the stipulations in the local regulations and laws. Use
of wiring which does not meet the specifications may give rise to electric shocks, electrical leakage, smoking and/or a fire.
Check that the product is properly earthed. (grounding work)
Incomplete earthing may cause electric shock.
Do not connect the earth line to a gas pipe, water pipe, lightning conductor, or a telephone earth line.
After completing the repair or relocation work, check that the ground wires are connected properly.
Install a circuit breaker that meets the specifications in the installation manual and the stipulations in the local regulations
and laws.
Install the circuit breaker where it can be easily accessed by the agent.
When installing the circuit breaker outdoors, install one which is designed to be used outdoors.
Under no circumstances must the power cable be extended. Connection trouble in the places where the cable is extended
may give rise to smoking and/or a fire.
Electrical wiring work shall be conducted according to law and regulation in the community and installation manual.
Failure to do so may result in electrocution or short circuit.
Do not supply power from the power terminal block equipped on the outdoor unit to another outdoor unit. Capacity overflow
may occur on the terminal block and may result in fire.
When carrying out electric connection, use the wire specified in the Installation Manual and connect and fix the wires
securely to prevent them applying external force to the terminals. Improper connection or fixing may result in fire.
Test run
Before operating the air conditioner after having completed the work, check that the electrical parts box cover of the indoor
unit and service panel of the outdoor unit are closed, and set the circuit breaker to the ON position. You may receive an
electric shock if the power is turned on without first conducting these checks.
When you have noticed that some kind of trouble (such as when an error display has appeared, there is a smell of burning,
abnormal sounds are heard, the air conditioner fails to cool or heat or water is leaking) has occurred in the air conditioner,
do not touch the air conditioner yourself but set the circuit breaker to the OFF position, and contact a qualified service
person. Take steps to ensure that the power will not be turned on (by marking "out of service" near the circuit breaker, for
instance) until qualified service person arrives. Continuing to use the air conditioner in the trouble status may cause
mechanical problems to escalate or result in electric shocks or other failure.
After the work has finished, be sure to use an insulation tester set (500V Megger) to check the resistance is 1 MΩ or more
between the charge section and the non-charge metal section (Earth section). If the resistance value is low, a disaster such
as a leak or electric shock is caused at user's side.
Upon completion of the installation work, check for refrigerant leaks and check the insulation resistance and water drainage.
Then conduct a test run to check that the air conditioner is operating properly.
Explanations given to user
Upon completion of the installation work, tell the user where the circuit breaker is located. If the user does not know where
the circuit breaker is, he or she will not be able to turn it off in the event that trouble has occurred in the air conditioner.
If you have discovered that the fan grille is damaged, do not approach the outdoor unit but set the circuit breaker to the OFF
position, and contact a qualified service person(*1) to have the repairs done. Do not set the circuit breaker to the ON position
until the repairs are completed.
After the installation work, follow the Owner's Manual to explain to the customer how to use and maintain the unit.
