5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your air conditioner.
Cleaning the Air Filter:
The air filter should be cleaned every two weeks, or more frequently depending on usage and air quality.
- Unplug the unit from the power outlet.
- Locate and remove the air filter from the back or side of the unit.
- Wash the filter under running tap water (warm, not hot) or use a vacuum cleaner to remove dust.
- Allow the filter to air dry completely before re-installing it. Do not expose to direct sunlight.

However, in high humidity conditions or when using dehumidifier mode, the internal water tank may fill up. When the tank is full, the unit will stop operating and display an indicator.
- Unplug the unit.
- Place a shallow pan or tray under the drainage port at the bottom rear of the unit.
- Remove the drainage plug to allow water to flow out.
- Once drained, replace the drainage plug securely.
Cleaning the Unit Exterior:
- Wipe the exterior with a soft, damp cloth.
- Do not use harsh chemicals, abrasives, or flammable liquids.
