5. Maintenance
Regular maintenance ensures efficient operation and extends the lifespan of your air conditioner.
5.1 Air Filter Cleaning
Clean the air filter every two weeks or more frequently if the unit is used in a dusty environment.
- Unplug the unit from the power outlet.
- Locate the air filter panel, usually on the back or side of the unit.
- Remove the filter.
- Wash the filter with warm, soapy water. Rinse thoroughly and allow it to air dry completely before reinstalling. Do not expose to direct sunlight.
- Reinstall the dry filter and close the panel.
5.2 Water Drainage
The unit has an internal water tank that collects condensed water. When the tank is full, the unit will stop operating and display an error code (e.g., "FL").

- Continuous Drainage (Recommended for Dry Mode): Connect the provided drain hose to the continuous drain port and route it to a floor drain or a larger container. Ensure the hose is sloped downwards for proper drainage.

If storing the unit for an extended period:
- Drain all condensed water completely.
- Clean the air filter.
- Run the unit in Fan mode for a few hours to dry the interior.
