- Fan Speed Control: Multiple fan speed options are available to adjust airflow intensity.
- Operation Modes: Choose from Cooling, Auto, Dehumidification, Heating (for heat pump models), and Fan modes to suit different climate needs.
- Jet Cool: A feature on the wireless remote for rapid cooling at super high fan speed.
- Plasma Purification (Optional): Available on some models via the wireless remote to start or stop the plasma-purification function.

- Forced Operation: A manual ON/OFF button on the unit allows for basic operation in case the remote control is unavailable. This mode operates in cooling at high fan speed and resets in 18 minutes.
- Auto Restart: After a power failure, the unit automatically resumes previous operating conditions. The fan starts at a low speed, followed by the compressor after 2.5-3 minutes, then the fan speed returns to its previous setting. This function is enabled by default but can be disabled/enabled via a specific button sequence on the ON/OFF button.
Maintenance Features
Regular maintenance is crucial for optimal performance and longevity of the air conditioner:
- Cleaning the Unit: The indoor unit should be cleaned with a soft, dry cloth. Harsh detergents, solvents, or water hotter than 40°C should not be used to prevent deformation, discoloration, or damage.
- Air Filters:
- Frequency: Check and clean air filters every 2 weeks or more often if necessary.
- Procedure: Remove filters as per diagrams, clean with a vacuum cleaner or warm soapy water. For stubborn dirt, use a detergent solution in lukewarm water. Dry thoroughly in the shade before reinstalling.
- Plasma Filters:
- Frequency: Check and clean plasma filters every 3 months or more often if necessary.
- Procedure: Remove filters (after air filters), clean with a vacuum cleaner. If dirty, wash with water and dry well in the shade before reinstalling.
- Safety Note: Do not touch the plasma filter within 10 seconds of opening the inlet grille to avoid electric shock.
- Deodorizer Filters:
- Frequency: Remove and expose to direct sunlight for 2 hours to refresh.
- Procedure: Reinsert into original position after exposure.
- Replacing Picture/Photograph: The front panel allows for easy replacement of the displayed image. This involves turning off power, opening the front panel, removing the existing picture/mat, placing the new image between the mat and the old picture (or directly if no mat is used), and securing the panel.
- Long-Term Storage: If the air conditioner will not be used for an extended period:
- Operate in Air Circulation mode for 2-3 hours to dry internal mechanisms.
- Turn off the circuit breaker.
- Remove batteries from the remote controller.
- Re-use After Storage:
- Clean and reinstall air filters.
- Check that indoor/outdoor unit air inlets and outlets are not blocked.
- Verify that the ground wire is correctly connected.
Safety Precautions: Always turn off the main power, disconnect the circuit breaker, and unplug the power cord before performing any maintenance. Contact authorized service technicians for repairs or complex maintenance.
