Thank you very much for purchasing TOSHIBA Air Conditioner.
Please read this owner’s manual carefully before using your Air Conditioner.
• Be sure to obtain the “Owner’s manual” and “Installation manual” from constructor (or dealer).
Request to constructor or dealer
• Please clearly explain the contents of the Owner’s manual and hand over it.
ADOPTION OF NEW REFRIGERANT
This Air Conditioner is a new type which adopts a new refrigerant HFC (R410A) instead of the conventional
refrigerant R22 in order to prevent destruction of the ozone layer.
This appliance is not intended for use by person (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.

1PRECAUTIONS FOR SAFETY
WARNING
WARNINGS ABOUT INSTALLATION
• Make sure to ask the qualified installation professional in electric work to
install the air conditioner.
If the air conditioner is inappropriate installed by yourself, it may cause
water leak, electric shock, fire, and so on.
• Be sure to connect earth wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning rods or
ground wires for telephone wires.
• If you install the indoor 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.
• Check whether the piping work has been properly completed.
When existing pipes are used and if they are not constructed properly, the
refrigerant gas may leak. Contact the installation company and confirm that
the piping work has been properly completed. For details of installation of
the air conditioner, refer to the Installation Manual. Use tools and piping
materials for R410 only. Failure to do so or improper installation may cause
a burst of pipe, resulting in injury.
WARNINGS ABOUT OPERATION
• Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to
have a service person do it.
The self cleaning function of the air conditioner causes the internal fan to run at a high speed in some modes
even while the air conditioner is not working, which may cause injury.
Do not attempt it yourself.
• Avoid cooling the room too strong or exposing the human body to cool breeze for a long time as it is bad
for the health.
• When you notice something abnormal with the air conditioner (smells like something scorching, poor
cooling, etc.), immediately turn off the main switch, the circuit breaker, from the mains to stop the air
conditioner, and contact the dealer.
If the air conditioner is continuously operated with something abnormal, it may cause machine failure,
electric shock, fire, and so on.
WARNINGS ABOUT MOVEMENT AND REPAIR
• When the air conditioner cannot cool or heat a room well, contact the dealer from whom you purchased the
air conditioner as refrigerant leakage is considered as the cause. In the case of repair that requires refill of
refrigerant, ask service personnel about details of the repair.
The refrigerant used in the air conditioner is harmless.
Generally, the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove
burner in the room catches fire, it may generate toxic gas.
When you ask service personnel for repairing refrigerant leakage, confirm that the leakage portion has
been completely repaired.
• Do not move or repair any unit by yourself.
Since there is high voltage inside the unit, you may get electric shock when removing the cover and main
unit.
• Whenever the air conditioner needs repair, make sure to ask the dealer to do it.
If it is repaired imperfectly, it may cause electric shock or fire.
• When moving the air conditioner for re-installing at another place, ask the dealer to do it. If it is imperfectly
installed, it may cause electric shock or fire.

CAUTION
TO DISCONNECT THE APPLIANCE FROM THE MAINS SUPPLY
• This appliance must be connected to the mains by means of a switch with a contact separation of at least
3 mm.
•The installation fuse 40A, 25A or 16A must be used for the power supply line of this air conditioner.
CAUTIONS ABOUT INSTALLATION (Be sure to confirm the following cautions.)
• Use an exclusive power circuit for the air conditioner. Use the rated voltage.
• Certainly lay the drain hose for perfect draining.
Bad drainage may cause flooding in the house and getting furniture wet.
• Make sure to connect the air conditioner to an exclusive power supply of the
rated voltage, otherwise the unit may break down or cause a fire.
• Do not install the unit in a place where inflammable gas may leak.
If inflammable gas accumulates around the unit, it may cause a fire.
CAUTIONS ABOUT OPERATION
• Carefully read this manual before starting the air conditioner.
There are many important things to keep in mind for daily operation.
• Do not use this air conditioner for special purpose such as preserving food,
precision instruments, art objects, breeding animals, car, vessel, etc.
• When the air conditioner is operated with a combustion appliance in the same
place, be careful of ventilation to let fresh air enter the room.
Poor ventilation causes oxygen shortage.
• 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.
• When the air conditioner is used in a closed room, be careful of sufficient ventilation of the room.
Poor ventilation causes oxygen shortage.
• Do not touch any switches with wet finger, otherwise you may get an electric shock.
• If the air conditioner won’t be used for a considerably long time, turn off the main switch or the circuit
breaker, for safety.
• Do not put anything on the outdoor unit nor step onto it.
If you do so, it may not only topple over the unit but also injure yourself.
• To make the air conditioner operate in its original performance, operate it within the range of the operating
temperature specified in the instructions.
Otherwise it may cause a malfunction, or water leak from the unit.
• Prevent any liquid from falling into the remote controller.
Do not spill juice, water or any kind of liquid.

6ADJUSTMENT OF WIND DIRECTION
For best cooling and heating performance, adjust the louvers (adjustment plates of up/down wind
direction) appropriately. Cold air descends and warm air rises, so to heat a room tilt the louvers
downward, and to cool a room tilt them horizontally.
CAUTION
Direct the louvers horizontally for cooling.
If the louvers stay pointed downward when cooling, condensation may form on the discharge port and/then
drops from the louvers.
NOTE
If the louvers stay pointed straight out horizontally when heating, the room temperature may be unevenly
distributed.
• When the air conditioner is not working, the louvers are directed horizontally automatically.
• The louvers are directed horizontally when heating begins, during defrost operation, or during the
minimum operation after reaching the set temperature.
When you make a swing or air direction setting at this time, the remote controller display varies with
the setting, but the louvers stay pointed straight out horizontally.
When the air conditioner starts heating, the louvers are directed to the set direction.
For cooling (COOL)
Direct the louvers horizontally.
For heating (HEAT)
Direct the louvers downward.
