WARNING
General
• Carefully read the Owner’s Manual before starting the air
conditioner. There are a number of important things to keep in
mind for daily operation.
• Ask for the installation to be performed by the dealer or a
professional. Only use a qualified installer to install an air
conditioner. If a non-qualified person installs an air conditioner,
it may result in problems such as fire, electric shock, injury, water
leakage, noise and vibration.
• 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.
• Places where the operation sound of the outdoor unit may cause
a disturbance. (Especially at the boundary line with a neighbor,
install the air conditioner while considering the noise.)
Transportation and storage
• While transporting the air conditioner, wear shoes with protective
toe caps, protective gloves, and other protective clothing.
• To transport the air conditioner, do not take hold of the bands
around the packing carton. You may injure yourself if the bands
should break.
• Before stacking the packing cartons for storage or transportation,
heed the precautions written on the packing cartons.
Failure to heed the precautions may cause the stack to collapse.
• The air conditioner must be transported in a stable condition.
If any part of the product is broken, contact your dealer.
Installation
• Only a qualified installer or qualified service person is allowed
to carry out the electrical work of the air conditioner. Under no
circumstances should this work be performed by an unqualified
individual since failure to carry out the work properly may result
in electric shocks and/or electrical leaks.
• After the installation work has been completed, have the installer
explain the circuit breaker positions. In the event an electrical
issue occurs with the air conditioner, set the circuit breaker to the
OFF position, and contact a service person.
• If the unit is installed 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 in close proximity
to a combustible gas. If a combustible gas leaks and becomes
concentrated around the unit, a fire may occur.
• If separately sold products are used, use TOSHIBA/Carrier
specified products only. Using unspecified products may cause
fire, electric shock, water leak or other failure.
• Connect the ground wire. Incomplete grounding may cause an
electric shock.
Operation
• 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 or qualified service person is allowed to remove
the intake grille of the indoor unit or service panel of the outdoor
unit to perform any type of work on the unit.
• Inside the air conditioner are high-voltage areas and rotating
parts. Due to the danger of electric shocks or of your fingers or
physical objects becoming trapped in the rotating parts, do not
remove the intake grille of the indoor unit or service panel of the
outdoor unit. When work involving the removal of these parts
is required, contact a qualified installer or a qualified service
person.

• Do not move or repair any unit by yourself. Since there is high
voltage inside the unit, you may get electric shock during removal
of the cover and main unit.
• Use of a stand more than 50 cm high to clean the filter of the
indoor unit or to carry out other such jobs constitutes working at
heights. Due to the danger of falling off the stand and injuring
yourself while working at heights, this kind of work should not be
done by unqualified individuals. When this kind of work must be
carried out, do not do it yourself.
Have a qualified installer or a qualified service person to perform
the work.
• Do not touch the aluminum fin of the outdoor unit. You may injure
yourself if you do so. If the fin must be touched, do not touch
it yourself. Contact a qualified installer or a qualified service
person.
• 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.
• Do not place any combustion appliance in a place where it is
directly exposed to the wind of the air conditioner, otherwise it
may cause imperfect combustion.
• When the air conditioner is operated with a combustion appliance
in the same place, ventilate the room adequately.
Poor ventilation may cause an oxygen shortage.
• When the air conditioner is used in a closed room, ventilate the
room. Poor ventilation may cause an oxygen shortage.
• Do not expose your body to cool air directly for a long time and
do not cool yourself excessively.
Doing so may result in a deteriorated physical condition and ill
health.
• Do not insert your finger or a stick into the air intake or outlet.
Doing so may result in injury as the fan is rotating at a high speed
inside the unit.
• Consult the shop where you purchased the unit if air conditioning
(cooling and heating) does not perform properly as a refrigerant
leakage may be the cause. Confirm the repair details with a
qualified service person when the repair includes additional
refrigerant charging.
• Stop running the air conditioner and turn off the breaker before
cleaning.
Otherwise, injury may result as the fan is rotating at a high speed
inside the unit.
Repairs
• If there is any kind of trouble (such as the check code display
appears, there is a burning smell, 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.
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 a 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 additional mechanical failures.
• If the fan grille is damaged, do not approach the outdoor unit.
Set the circuit breaker to the OFF position and contact a qualified
service person to have the repairs done. Do not set the circuit
breaker to the ON position until the repairs are completed.
• If there is danger of the indoor unit falling, do not approach
the indoor unit. Set the circuit breaker to the OFF position and
contact a qualified installer or a qualified service person to refit
the unit. Do not set the circuit breaker to the ON position until the
unit has been refitted.
• If there is danger of the outdoor unit toppling over, do not
approach the outdoor unit. Set the circuit breaker to the OFF
position and contact a qualified installer or a qualified service
person to correct the issue. Do not set the circuit breaker to the
ON position until the issue is corrected.
• Do not customize the unit. Doing so may result in fire, electric
shock or other failure.

• Use an exclusive power supply circuit for the air conditioner
at the rated voltage. An insufficient power supply capacity or
inappropriate installation may cause fire.
• Confirm that the outdoor unit is securely attached to the base.
Otherwise, the unit may fall and cause damage to the unit,
property, or people.
Cautions about operation
• Do not use this air conditioner for special purposes such as
preserving food, precision instruments, art objects, breeding
animals, car, boats, etc..
• Do not operate the buttons with wet hands. Doing so may cause
electric shock.
• If the air conditioner will not be used for a considerably long time,
turn off the main switch or the circuit breaker, for safety.
• To ensure the air conditioner operates in its original performance,
operate it within the range of the operating temperature specified
in the instructions. Otherwise the unit may malfunction, or leak
fluid.
• Prevent any liquid from falling into the remote control. Do not spill
juice, water or any kind of liquid.
• Do not wash the air conditioner. Doing so may result in electric
shock.
• Check whether the installation base and other equipment have
deteriorated after being used for a long time. Leaving them in
such a condition may result in the unit falling down and causing
injury.
• Do not leave flammable sprays or other flammable materials near
the air conditioner, and do not spray flammable aerosol directly
into the air conditioner. The unit may catch fire.
• Stop running the air conditioner and turn off the breaker before
cleaning.
Otherwise, injury may result as the fan is rotating at a high speed
inside the unit.
• Ask an authorized dealer or qualified service person to clean the
air conditioner.
Cleaning the air conditioner in an improper manner may cause
damage to plastic parts, insulation failure of electric parts, and
result in a malfunction. In worst case, it may result in water
leakage, electric shock, smoke emission and fire.
• Do not put a water container, such as a vase, on the unit.
Water intrusion into the unit may occur and it may cause
deterioration of electric insulation and result in electric shock.
• Do not wash air conditioners with pressure washers. Electric
leaks may cause electric shocks or fires.

In addition to the maintenance, it is recommended
that you have a inspection (charges apply) performed
by the dealer where you purchased the unit, etc.
CAUTION
 Perform high-pressure cleaning for the heat
exchanger.
If commercially available detergent (strong alkaline
or acid cleaning agent) is used, the surface treatment
of the heat exchanger will deteriorate, which may
degrade the self cleaning performance. For details,
contact our sales department or the dealer where
you purchased the unit.
