Indoor Unit Parts And Major Functions

Unit Parts

Operating Conditions

Use the system at the following temperature for safe and effective operation. If the air conditioner is used outside of the following conditions, it may malfunction or be less efficient.

Features

Default Setting
When the air conditioner restarts after a power failure, it will default to the factory settings (AUTO mode, AUTO fan, 24°C (76°F)). This may cause inconsistencies on the remote control and unit panel. Use your remote control to update the status.

Auto-Restart (some models)
In case of power failure, the system will immediately stop. When power returns, the Operation light on the indoor unit will flash. To restart the unit, press the ON/OFF button on the remote control. If the system has an auto restart function, the unit will restart using the same settings.

Louver Angle Memory Function (Optional)
Some models are designed with a louver angle memory function. When the unit restarts after a power failure, the angle of the horizontal louvers will automatically return to the previous position. The angle of the horizontal louver should not be set too small as condensation may form and drip into the machine. To reset the louver, press the manual button, which will reset the horizontal louver settings.

Refrigerant Leak Detection System (some models)
In the event of a refrigerant leak, the LCD screen will display “EC” and the LED indicator light will flash.

Energy Saving Tips

• DO NOT set the unit to excessive temperature levels.
• While cooling, close the curtains to avoid direct sunlight.
• Doors and windows should be kept closed to keep cool or warm air in the room.
• DO NOT place objects near the air inlet and outlet of the unit. This will reduce the efficiency of the unit.
• Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.
• If you don’t plan to use the unit for a long time, remove the batteries from the remote control.
• Clean the air filter every two weeks. A dirty filter can reduce cooling or heating efficiency.
• Adjust louvers properly and avoid direct airflow.

Care And Maintenance

Safety Precautions

• Contact an authorized service technician for repair or maintenance of this unit. Improper repair and maintenance may cause water leakage, electrical shock, or fire, and may void your warranty.
• DO NOT substitute a blown fuse with a higher or lower amperage rating fuse, as this may cause circuit damage or an electrical fire.
• Please make sure the drain hose is set up according to the instructions. Failure to do so could cause leakage and result in personal property damage, fire and electric shock.
• Make sure that all wires are connected properly. Failure to connect wires according to instructions can result in electrical shock or fire.

Unit Maintenance

BEFORE CLEANING OR MAINTENANCE

• Always turn off your air conditioning system and disconnect its power supply before cleaning or maintenance.
• DO NOT use chemicals or chemically treated cloths to clean the unit
• DO NOT use benzene, paint thinner, polishing powder or other solvents to clean the unit. They can cause the plastic surface to crack or deform.
• DO NOT wash the unit under running water. Doing so causes electrical danger.
• DO NOT use water hotter than 40°C (104°F) to clean the front panel. This can cause the panel to deform or become discolored.
• Clean the unit using a damp, lint-free cloth and neutral detergent. Dry the unit with a dry, lint-free cloth.

How To Clean The Air Filter

The filter prevents dust and other particles from entering the indoor unit. Dust buildup can reduce the efficiency of the air conditioner. For optimum efficiency, clean the air filter every two weeks or more frequently if you live in a dusty area. Replace the filter with a new one if it’s heavily clogged and unable to be cleaned.

WARNING: DO NOT REMOVE OR CLEAN THE FILTER BY YOURSELF 

Removing and cleaning the filter can be dangerous. Removal and maintenance must be performed by a certified technician.

NOTE: In households with animals, you will have to periodically wipe down the grille to prevent blocked airflow due to animal hair.

1. Unlock the grille by pushing the two tabs towards the middle simultaneously.

2. Unplug the display panel cable from the control box on the main body.

   

3. Detach the grille from the main unit by holding the grille at a 45° angle, lifting it up slightly, and then pulling the grille forward.
   NOTE: Some models include an auto-lifting panel function, which allows the grill to move vertically and simplifies the filter cleaning process.

   

4. Remove the air filter.
5. Clean the air filter by vacuuming the surface or washing it in warm water with mild detergent.
   1. If using a vacuum cleaner, the inlet side should face the vacuum.

   2. If using water, the inlet side should face down and away from the water stream.

      

6. Rinse the filter with clean water and allow it to air-dry. DO NOT let the filter dry in direct sunlight.
7. Reinstall the filter.
8. Reinstall the front grille and reconnect the display panel cable to the control box on the main body.

Repairing Refrigerant Leaks

WARNING

• If the refrigerant leaks, turn off the air conditioner and any combustible heating devices, ventilate the room and call your dealer immediately. Refrigerant is both toxic and flammable. DO NOT use the air conditioner until the leak is repaired.
• When the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant concentration from exceeding the safety limit in the event of refrigerant leakage. Concentrated refrigerant causes a severe health and safety threat.

Refrigerant Leak Detection System (some models)

• In the event of a refrigerant leak, the LCD screen will display “EC” and the LED indicator light will flash.

Preparation For Periods Of Non-Use

Maintenance after Extended Non-Use
