To automatically swing the air flow direction Perform this function while the air conditioner is in operation. Push the SWING button on the remote controller.

■ To stop the function, push the SWING button again.

■ To change the swing direction, push the AIR DIRECTION button.

CAUTIONS

- The AIR DIRECTION and SWING buttons will be disabled when the air conditioner is not in operation (including when the ON TIMER is set).

- Do not operate the air conditioner for long hours with the air flow direction set downward during the cooling or dry operation. Otherwise, condensation may occur on the surface of the vertical air flow louver and cause dew dripping.

- Do not move the vertical louver manually. Always use the AIR DIRECTION button. If you move the louver manually, it may malfunction during operation. If the louver malfunctions, stop the air conditioner once and restart it.

- When the air conditioner is started immediately after it was stopped, the vertical air flow louver might not move for 10 seconds or so.

Adjusting the Horizontal Air Flow Direction Preparation:

For the cooling or dry operation, move the vertical air flow louver downward using the AIR DIRECTION button on the remote controller.

■ Take hold of the lever on the horizontal air flow grilles and move them to adjust the air flow direction as required.

■ For the cooling or dry operation, return the vertical air flow louver to the original position using the AIR DIRECTION button on the remote controller.

If your use the AIR DIRECTION button to set the vertical air flow direction, the direction will move downward at first, then turn automatically to the direction as you desire.

When you stop operating with the remote controller, the vertical air flow louver will shut automatically.

HOW THE AIR CONDITIONER WORKS

AUTOMATIC OPERATION

• The air conditioner selects and operates in one of the operating modes of cooling, heating (cooling only type without) or fan only, depending on the room temperature.
  ■ The air conditioner will control room temperature automatically round the temperature point set by you.
  ■ If the Auto mode is uncomfortable, you can select the desired conditions manually.

ECONOMIC OPERATION

When your push ECONO button during cooling, heating (cooling only type without), or AUTO operation, the air conditioner will start following operation. The fan speed will be automatically controlled. In the operation suppression zone where capacity is kept to the minimum, overcooling is prevented by raising the temperature setting by 1^iC after 1 hour and by 2^iC after 2 hours of operation. The room temperature is thus regulated between the operation suppression zone and the set temperature. (It depends on the outdoor 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.

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

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

TEMPORARY OPERATIONS

Temporary Operation

This function is used to operate the unit temporarily in case you misplace the remote controller or its batteries are exhausted.

• Set the TEMPORARY switch to the AUTO position in order to start the automatic operation.
• The COOL position is provided for test runs of the unit, and automatic temperature control is cut off at this position. Never use the position for ordinary operation.

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.

This will protect the machine. (cooling only type without)

● 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.

• Warm air control

When the room temperature reaches the set temperature, the fan 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 outdoor and released into the room. that is so-called heat pump system. When the outdoor temperature is too low, you are recommended to use another heating apparatus in combination with the air conditioner.

Consideration for accumulated snow

Select the position for the outdoor unit where it will not be subject to snow drifts, accumulation of leaves or other seasonal debris. It is important that the air flow for the outdoor unit is not impeded as this will result in reducing heating or cooling performance. During the heating mode (cooling only type without) 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 on the indoor unit will start flashing when power is restored.

To restart operation, push the ON/OFF button on the remote controller.

Lighting or a car wireless telephone operating nearby may cause the unit to malfunction. Disconnect the unit with the power and then connect the unit with the power again. Push the ON/OFF button on the remote controller to restart it.

Air conditioner operating conditions

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

Cooling operation	Outdoor temperature: 18 to 43^iC
	Room temperature: 17 to 32^iC
	CAUTIONRoom 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	Outdoor temperature: -7 to 24^iC
	Room temperature: 0 to 27^oC
Dry operation	Outdoor temperature: 11 to 43^iC
	Room temperature: 17 to 32^iC

If air conditioner is used outside of the above conditions, safety protection features may come into operation.
