Familiarize yourself with the operating modes and features to maximize your comfort.
Operating Modes
The unit offers three primary operating modes: Cooling, Dehumidifying, and Fan.

5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your portable air conditioner.
Cleaning the Air Filter
The air filter should be cleaned every two weeks or more frequently depending on usage and air quality. A dirty filter can reduce efficiency and airflow.
- Unplug the unit from the power outlet.
- Locate and remove the air filter from the back or side of the unit.
- Wash the filter with warm, soapy water. Rinse thoroughly.
- Allow the filter to air dry completely before reinstalling. Do not expose to direct sunlight.
Water Drainage (Self-Evaporation)
This unit features a self-evaporation system, which significantly reduces the need for manual water drainage. Most condensed water is evaporated and expelled through the exhaust hose.
In high humidity conditions, some water may accumulate in the internal reservoir. If the reservoir becomes full, the unit will stop operating and display an error code. In such cases, manually drain the water:
- Unplug the unit.
- Place a shallow pan or tray under the drainage port (usually located at the bottom rear of the unit).
- Remove the drain plug to allow water to flow out.
- Once drained, replace the drain plug securely.

6. Troubleshooting
Before contacting customer support, please refer to the following common issues and solutions.
- Unit does not turn on: Check if the power cord is securely plugged into a working outlet. Ensure the unit is not in standby mode and the timer is not set to off.
- Unit is running but not cooling: Verify that the air filter is clean. Check if the exhaust hose is properly installed and not blocked. Ensure windows and doors are closed to prevent warm air from entering the room. The room temperature might be below the set temperature.
- Unit is noisy: Ensure the unit is placed on a flat, stable surface. Check for any obstructions in the air inlets or outlets.
- Water leakage: Check if the drain plug is securely in place. In high humidity, manual drainage might be required.
- Error codes: Refer to the specific error code displayed on the LED panel. Common codes relate to full water tanks or sensor malfunctions.
