5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your air conditioner.
5.1 Air Filter Cleaning
The air filters (evaporator and condenser filters) should be cleaned every two weeks or more frequently depending on usage and air quality.
- Unplug the air conditioner from the power outlet.
- Locate and remove the air filters from the back of the unit (refer to Image 3.1 for filter locations).
- Wash the filters with warm, soapy water. Rinse thoroughly.
- Allow the filters to air dry completely before reinstalling. Do not expose to direct sunlight.
5.2 Drainage
This unit is designed as a 'Non-Drain Type' for most cooling operations, meaning condensed water is typically evaporated and expelled with the exhaust air. However, in high humidity conditions, the internal water tank may fill. The unit has a continuous drainage hole for optional use.
- If the unit stops operating and displays a 'Full Water' indicator, manually drain the water.
- Locate the drainage hole at the bottom rear of the unit (refer to Image 3.1).
- Place a shallow pan or tray beneath the drainage hole.
- Remove the drain plug to allow water to flow out.
- Replace the drain plug once all water has been drained.
- For continuous drainage, connect a suitable drain hose (not included) to the drainage hole and direct it to a floor drain or bucket.
5.3 Storage
When storing the unit for an extended period:
- Unplug the unit and drain any remaining water.
- Clean the air filters.
- Run the unit in fan-only mode for a few hours to dry the internal components.
- Cover the unit with a plastic bag or cloth to protect it from dust.
- Store in a dry, cool place.
