PRECAUTIONS 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 you it may cause water leak,
electric shock, fire, and so on.
• Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes and lightning rods or
ground wires for telephone wires.
CAUTION
TO DISCONNECTTHE APPLIANCE FROMTHE 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 (10A) must be used for the power supply line
of this conditioner.
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.
Do not attempt it yourself.The cleaning diagram for the air filter is there for the
service person, and not for the customer.
• 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 some-
thing 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
• 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
CAUTIONS ABOUT INSTALLATION
Be sure to confirm the following cautions.
•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 purposes such as preserving
food, precision instruments, art objects, breeding animals, growing
potted plants, etc.
•Avoid exposing potted plants and animals to the wind of the air
conditioner, since it badly affects the health and growth of them.
•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.
•Check the concrete blocks, etc. of the base of the outdoor unit occa-
sionally.
If the base is left damaged or deteriorated, the unit may topple over and
inflict an injury to a person as the worst case.
•Do not put anything on the outdoor unit or 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.
CAUTIONS FOR REINSTALLATION / REPAIR
•Never modify the air conditioner; otherwise a fire or an electric shock
may be caused.
•For repair of the air conditioner, ask the dealer which you purchased the
air conditioner to repair it.
An incomplete repair may cause a fire or an electric shock.
•For transference and reinstallation of the air conditioner, ask the dealer
which you purchased it or a qualified professional. An incomplete instal-
lation causes a fire, an electric shock, an injury or water leakage.

HEAT : Heats the fresh air and sends it into the room
FAN : Sends the fresh air as it is
•The air conditioner with the fresh air intake unit controls temperature of the supply air so that it is close to
the setup temperature of the remote controller.
However temperature of the supply air may not be close to the setup temperature according to tempera-
ture of the fresh air or the operation condition of the indoor units for air conditioning in one line.
REQUIREMENT
•The air conditioner with the fresh air intake unit cannot control the room temperature.
•For control of the room temperature, an indoor unit for air conditioning is required separately.
Use Conditions
