1. SAFETY CAUTIONS
Read the following cautions carefully and
use your equipment properly.
There are two kinds of safety cautions and tips listed
here as follows:
WARNING....... Improper handling can lead to
such serious consequences as
death or severe injury.
CAUTION ........ Improper handling can lead to
injury or damage. It could also
have serious consequences
under certain conditions.
NOTE
Keep this operation manual handy so that you
can refer to them if needed.
Also, if this equipment is transferred to a new user,
make sure to hand over this operation manual to the
new user.
WARNING for operation
• Do not expose yourself directly to the cool air
currents too long nor allow the air in the
room to become too cold.
Doing so may make you feel sick or damage your
health.
• Do not put your fingers, rods, or other objects into
the air inlet or outlet while the fan is in operation.
Injury may result because the fan is rotating at
high speed.
• Flammable if refrigerant leaks.
The refrigerant used in the air conditioner is safe
and should not normally leak, but if it does leak
into a room, it will emit a noxious gas if it comes in
contact with any kind of heater, stove, or other similar objects.
Turn off any combustible heating devices, ventilate
the room, and contact the dealer where you purchased the unit.
When repairing a refrigerant leak, have a service
engineer check that the repair has been performed properly before running the unit again.
• Use only fuses of the correct capacity if a fuse
load switch is being used.
Using wires may cause breakdown and fire.
• Do not disassemble, modify, or repair.
This may cause water leakage, electric shock, or
fire. Only your dealer should attempt such procedures.
• If anything unusual occurs (e.g., a burning
smell), stop the operation of the air conditioner
and shut off the power.
Leaving the unit running under such circumstances may cause breakage, electrical shock, or
fire.
Contact your dealer.
• Consult the dealer if the air conditioner submerges owing to a natural disaster, such as a
flood or typhoon.
Do not operate the air conditioner in that case, or
otherwise a malfunction, electric shock, or fire may
result.
• Do not operate the air conditioner when using
a room fumigation - type insecticide.
Failure to observe could cause the chemicals to
become deposited in the unit, which could endanger the health of those who are hypersensitive to
chemicals.
CAUTION for operation
• Do not use the air conditioner for purposes
other than air conditioning.
Do not use the air conditioner to keep food, animals, plants, precision instruments, or works of art
cool.
Otherwise, their quality deterioration will result.
• Do not remove the fan guard of the outdoor
unit.
The exposed fan may cause injury.
• Do not place items under the indoor unit which
may be damaged by water.
Drips may fall in the following cases: 80% or higher
in humidity, clogged drain outlet, or foul air filter.

• Do not locate combustion appliances in places
exposed to the air that blows from the air conditioner.
The airflow may cause incomplete combustion of
the combustion appliances.
• Consult with the dealer for cleaning the interior
of the indoor units.
Incorrect cleaning may damage the plastic parts
and cause failures, such as water leakage, and an
electric shock may result.
• Do not mount on the outdoor unit or place any
object on it.
Falling, tumbling, and injury may result.
• Do not place flammable sprays near or actually
spray them on the unit.
Ignition may result.
• Do not allow the fan to blow directly on plants
or animals.
This may have an unwanted effect on the plants or
animals.
• Do not touch the air inlets or aluminum fins of
the outdoor or indoor units.
Touching them may result in injury.
• Do not disassemble the remote controller.
An electric shock or a failure in the remote controller may result if you touch the interior of the remote
controller. Contact your dealer for the internal
inspection of the remote controller.
• Do not start or stop operating the air conditioner with the power supply breaker turned
ON or OFF.
Otherwise, fire or water leakage may result.
Furthermore, the fan will rotate abruptly if power
failure compensation is enabled, which may result
in injury.
• Do not operate the air conditioner with wet
hands.
This may cause electric shock.
• Never press the button of the remote controller
with a hard, pointed object.
The remote controller may be damaged.
• Do not locate containers holding water (e.g.,
flower vases) on the indoor unit of floor mounting type.
The water may enter the unit and an electric shock
or fire may result.
• Do not wash the outdoor or indoor units with
water.
An electric shock or fire may result.
• Ventilate the room sufficiently from time to
time if combustion appliances are used in the
same room.
If the room is not ventilated sufficiently, oxygen
deficiency may result.
• After a long use, check the unit stand and fitting for damage.
If they are left in a damaged condition, the unit
may fall and topple down and result in injury.
• Be sure to stop the operation, and turn the
breaker off before cleaning.
This may cause electric shock and injury.
• Do not locate objects around the outdoor unit
and do not let leaves and other debris accumulate around the unit.
Leaves are a hotbed for small animals that can
enter the unit, and cause the outdoor unit to malfunction, generate smoke, or result in fire if they
come in contact with electrical parts.
• Watch your steps at the time of air filter cleaning etc.
If the scaffold is unstable, you may fall or topple
down, thus causing injury.
• Do not wipe the controller operation panel with
benzine, thinner, chemical dustcloth, etc.
The panel may get discolored or the coating
peeled off. If it is heavily dirty, soak a cloth in
water-diluted neutral detergent, squeeze it well
and wipe the panel clean. And wipe it with another
dry cloth.
• The appliance is not intended for use by young
children or infirm persons without supervision.
• Young children should be supervised to ensure
that they do not play with the appliance.
