Important safety precautions Read all instructions before using.

To prevent injury to the user or other people and property damage, the following instructions must be followed.

■ Incorrect operation due to ignoring of instruction will cause harm or damage, the seriousness is classified by the following indications.

WARNING

: This symbol indicates the possibility of death or serious injury.

CAUTION

: This symbol indicates the possibility of injury or damage to properties only.

■ Meanings of symbols used in this manual are as shown below.

				Be sure not to do.
				Be sure to follow the instruction.

WARNING

■ Do not install, remove and reinstall the unit by yourself.

• Improper installation will cause water leakage, electrical shock, or fire. Please consult authorized dealer or specialist for the installation work. Please note fault caused by improper installation is not covered by warranty.
• Unit must be installed in an easily accessible area. Any additional cost required to hire a special equipment to service the unit will be the responsibility of the customer.

CAUTION

Please confirm the following important points during installing.

■ This room air conditioner must be earthed.

It may cause electrical shock if grounding is not perfect.

■ Do not install the unit at place where leakage of gas may occur and/or in an explosive atmosphere.

In case gas leaks, the gas may accumulate the unit and it may cause fire ignition.

■ Confirm drainage piping is connected properly.

If it is not connected perfectly, it may cause water leakage and dampen the furniture.

■ The reverse cycle system of the air conditioner is based on the air cooling type heat pump which absorbs heated air from the outdoor unit and discharges it indoor.

Therefore if the outdoor unit is exposed to very low temperature, specifically below 0^ C, the heating capacity drops off rapidly.

WARNING

- Otherwise, it will cause electrical shock or fire due to heat generation.

- It will cause electrical shock or fire due to heat generation.

- It will cause electrical shock or fire. - If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a hazard.

Auto Operation

1 Press the Start/Stop button. The unit will respond with a beep. 2 Open the door on the remote control. To select Auto Operation, press the Operation Mode Selection button. Each time the button is pressed, the operation mode is shifted in the direction of the arrow. 3 The temperature and fan speed are automatically set by the electronic controls based on the actual room temperature. If you want to change the set temperature, close the door on the remote control and press the Room Temperature Setting buttons. The cooler or warmer you feel, the more times (up to two times) you should press the button. The set temperature will then be changed automatically. 4 To raise the temperature To lower the temperature

During Auto Operation:

☐ You cannot switch the indoor fan speed. It has already been set by the Fuzzy rule.
☐ If the system is not operating as desired, manually switch to another mode. The system will not automatically switch from the cooling mode to the heating mode, or from heating to cooling, it must be done by manually resetting.
☐ During Auto Operation, pressing the Airflow direction Start/Stop button makes the horizontal louvers swing up and down automatically. If you want to stop auto-swing, press the Airflow Direction Start/Stop button again.

Healthy Dehumidification Operation

□ Never use any of the followings:

• Water hotter than 40^ C Could cause deformation and/or discoloration.
• Volatile substances Could damage the surfaces of the air conditioner.

• Lift the front access panel and pull the filter tab slightly forward to remove the filter.
  ● Clean the filter with a vacuum or warm, soapy water.

- If dirt is conspicuous, wash with a solution of detergent in lukewarm water.

- If hot water (40°C or more) is used, it may be deformed.

● After washing with water, dry well in the shade.
● Re-install the air filter.

Air Purifying Filters(Option)

This filter consists of two filters. One is electrostatic filter to remove very fine dust as small as 0.1 micron such as tobacco smoke and pollen etc., the other is deodorant filter to remove unpleasant smell such as food, sweat, and fungus.

Helpful information

The air filters are your electric bill.

If the air filters become clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air conditioner will be wasted.

Troubleshooting Tips! Save time and money!

Check the following points before requesting repairs or service.... If the fault persists, please contact your dealer or service center.

Have you made a mistake in timer operation?Has the fuse blown or has the circuit breaker been tripped?	Check that this is not a damp smell exuded by the walls, carpet, furniture, or cloth items in the room.	Condensation occurs when the airflow from the air conditioner cools the warm room air.	This is the protector of the mechanism.Wait about three minutes and operation will begin.
Is the air filter dirty? See air filter cleaning instructions.(Refer to page 19)Has the temperature been set incorrectly?Are the indoor unit's air inlet or outlet vents obstructed?	For a noise that sounds like water flowing.-This is the sound of freon flowing inside the air conditioner unit.For a noise that sounds like the compressed air releasing into atmosphere.-This is the sound of the dehumidifying water being processed inside the air conditioning unit.	Are the batteries depleted?Are the batteries inserted in the opposite (+) and (-) directions?	This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature.

NOTE

WATER RESISTANT: The outdoor side of this appliance is WATER RESISTANT. The indoor side is not water resistant and should not be exposed to excess water.
