PRECAUTIONS FOR SAFETY

DANGER

• DO NOT ATTEMPT TO INSTALL THIS UNIT BY YOURSELF. THIS UNIT REQUIRES QUALIFIED INSTALLER.

• DO NOT ATTEMPT TO REPAIR THE UNIT BY YOURSELF. THIS UNIT HAS NO COMPONENTS WHICH YOU CAN REPAIR.

• OPENING OR REMOVING THE COVER WILL EXPOSE YOU TO DANGEROUS VOLTAGES.

• TURNING OFF THE POWER SUPPLY WILL NOT PREVENT POTENTIAL ELECTRIC SHOCK.

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.

Zeolite filter Purifying filter

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 operated together with a combustion appliance in the same place, be careful of ventilation to let fresh air into the room. Poor ventilation causes oxygen shortage.

• 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.

AIR CONDITIONER OPERATIONS AND PERFORMANCE

Three-minute protection feature

A protection feature prevents the air conditioner from being activated for approximately 3 minutes when it is restarted immediately after operation or when the power supply switch is set to on. This will protect the machine.

Heating characteristics Preheating operation

The air conditioner will not deliver warm air immediately after it is started. Warm air flows out after approximately 5 minutes when the indoor heat exchanger warms up. (The PRE.DEF lamp is on during this intervals indicating the preheating operation.)

Warm air control

When the room temperature reaches the set temperature, the fan indoor speed is automatically reduced to prevent a cold draft. At this time, the outdoor unit will stop.

Defrosting

If the outdoor unit is frosted during heating operation, defrosting is started automatically (for approximately 5 to 10 minutes) to maintain the heating effect, and the PRE.DEF lamp is on.

• The fans in both the indoor and outdoor units stop during the defrost operation.

• During defrost operation, defrosted water is drained from the bottom plate of the outdoor unit.

Heating capacity

In the heating operation, heat is absorbed from outdoors and released into the room. That is called the heat pump system. When the outdoor temperature is too low, to use another heating apparatus in combination with the air conditioner is recommended.

Consideration for accumulated snow

Select the position for the outdoor unit where it will not be subjected to snow drifts, accumulation of leaves or other seasonal debris. It is important that the air flow of the outdoor unit is not impeded as this will result in reduced heating or cooling performance. During the heating mode, and at sub-zero temperatures, the water drained off the outdoor unit as a result of the automatic defrost may accumulate and freeze. It is important that adequate drainage or a soak-way is provided.

Power failure

Power failure during operation will stop the unit completely.

• The OPERATION lamp (green) on the indoor unit will start flashing when power is restored.

• To restart operation, push the START/STOP button on the remote control.

• Lightning or a car wireless telephone operating nearby may cause the unit to malfunction. Turn the power

supply switch to off and then to on. Push the START/STOP button on the remote control to restart.

Air conditioner operating conditions

For proper performance, operate the air conditioner under the following temperature conditions:

Cooling operation

Outdoor temperature: 15°C to 43°C Room temperature: 21°C to 32°C

CAUTION

Room relative humidity – less than 80%. If the air conditioner operates in excess of this figure, the surface of the air conditioner may attract condensation.

Heating operation

Dry operation

If the air conditioner is used in conditions other than above, safety protection features may come into operation.

Outdoor temperature: –10°C to 24°C Room temperature: Less than 28°C Outdoor temperature: 15°C to 43°C Room temperature: 17°C to 32°C
