WARNING

WARNING ABOUT INSTALLATION

• Make sure to ask a dealer or a store specialized in electric work to install the air conditioner.
  If the air conditioner is imperfectly installed by yourself, it may cause some problems such as water leak, electric shock, fire, and so on.
• Ground the air conditioner without fail.
  Do not connect the ground wire to gas pipe, water pipe, lightning rod or ground wire of telephone. If the air conditioner is imperfectly grounded, it may cause electric shock.

CAUTION

TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SUPPLY This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a contact separation of at least 3 mm.

WARNING ABOUT OPERATION

• Avoid cooling the room too strong or exposing the human body to cool wind for a long time, because it is bad for the health.
• Do not insert fingers and sticks into the air outlet and air inlet to avoid getting injured and damaging the machine, because there are fans running at a high speed inside both the air inlet and air outlet.
• When you are aware of something abnormal with the air conditioner (smells something scorching, cools weak, etc.), immediately turn off the main switch, the circuit breaker, from the main power supply to stop the air conditioner, and make contact with the dealer. If the air conditioner is continuously operated with something abnormal, it may cause machine failure, electric shock, fire, and so on.
• Do not spill water or other liquid on the indoor unit. If the unit is wet, it may cause an electric shock.

WARNING ABOUT MOVEMENT AND REPAIR

• Do not move nor repair any unit by yourself.
  Since there is high voltage inside the unit, you may get an electric shock when removing the cover and main unit.
• When moving the air conditioner for re-installing in another place, ask the dealer to do it. If it is imperfectly installed, it may cause electric shock or fire.

CAUTION

CAUTIONS ABOUT INSTALLATION

•Certainly lay the drain hose for perfect draining.
Wrong 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. The manual includes many important things for daily operation.
• Do not use this air conditioner for other purposes such as preserving food, precision instruments, art objects, breeding animals, growing potted plants, etc. Do not install this air conditioner in a special-purpose room such as a ship or any kind of vehicle, otherwise it deteriorates the machine performance.
• Avoid exposing potted plants and animals to wind of the air conditioner, because it badly affects the health and growing of them.
• 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 operation button with wet finger; otherwise, you may get an electric shock.
• Do not place any combustion appliance in a place where it is directly exposed to wind of the air conditioner; otherwise, it may cause imperfect combustion.
• When the air conditioner won't be used for a considerably long time, turn off the main switch or the circuit breaker, for safety. Disconnection from the power supply prevents the unit from lightning and power source surge.
• Do not put a vessel with water such as a vase on the unit, because water may possibly sink into the unit and will bring about electric shock because of deterioration in electric insulation.
• Check the concrete blocks, etc. underneath the outdoor unit occasionally. If the base is left damaged or deteriorated, the unit may topple over and inflict an injury on a person as the worst case.
• Do not wash the unit with water. It may cause an electric shock.
• Do not use alcohol, benzene, thinner, glass cleaner, polishing powder, etc. for cleaning the unit, because they deteriorate or damage the air conditioner.
• When cleaning the unit, make sure to turn off the main switch or circuit breaker beforehand for preventing you from getting injured by the electric fan running inside.
  For details of cleaning method, refer to "Maintenance" on page 17 and 18.
• 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 demonstrate its original performance, operate it within the range of the operating temperature specified in the instructions. Otherwise it may malfunction, break down or water may leak from the unit.

HOW THE AIR CONDITIONER WORKS

Automatic Operation

• The air conditioner selects and operates in one of the operating modes of cooling or fan only, depending on the room temperature.
• If the AUTO mode is uncomfortable, you can select the desired conditions manually.

Room temperature in operation	Operating condition
The set temperature +1°C or higher (in case that the room is hot)	Cooling operation	Performs the cooling operation at a temperature 1°C higher than the setting.
The set temperature -1°C to +1°C	Fan only operation	Performs the fan only operation (low speed) while monitoring the room temperature. When the room temperature changes, the air conditioner will select the cooling mode.

Hi POWER operation

When you press the Hi POWER button during cooling or A operation, the air conditioner will start the following operation.

•Cooling operation

Performs the cooling operation lower than the setting temperature.

When the room temperature is above the setting temperature, air flow is directed downward. In addition, fan speed is high*. Once room temperature is within 1^ C of the setting temperature, air flow is returned to its regular direction to cool the entire room with maximum efficiency.

* Noise level raises in accordance with fan speed.

ECO timer operation

When you press the ECO button during cooling or A operation, the air conditioner will start the following operation. The fan speed will be automatically controlled.

•Cooling operation ( )

In the operation suppression zone, where capacity is kept to the minimum, overcooling is prevented by raising the temperature setting by 1^ C after 1 hour and by 2^ C after 2 hours of operation.

The room temperature is thus regulated between the operation suppression zone and the set temperature.

Operation starts 1°C 2°C Operation suppression zone 1 hour 2 hours Set temperature

DRY operation (∅)

The dry mode will automatically select the cooling dry operation based on the difference between the set temperature and the actual room temperature.

•Cooling dry operation

This operation is performed when the room temperature is higher than the set temperature.

The temperature is regulated while dehumidifying by repeated turning on and off of the cooling operation or fan only operation.

The fan speed display will indicate AUTO and low speed will be used.
