6. Maintenance
6.1. Filter Cleaning
The unit is equipped with a removable and washable double-layer filter. Regular cleaning of the filter is essential to maintain air quality and unit efficiency. Clean the filter every two weeks or more frequently depending on usage and air quality.
- Unplug the air conditioner from the power outlet.
- Locate and remove the filter from the back or side of the unit.
- Wash the filter under running water (warm, not hot) or use a vacuum cleaner to remove dust.
- Allow the filter to air dry completely before reinserting it into the unit. Do not expose to direct sunlight.
6.2. Water Drainage
The Acekool portable air conditioner 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.

Figure 6.2: This image provides a close-up view of the rear of the portable air conditioner, highlighting the self-evaporation system and the internal components that manage water drainage, effectively reducing the need for manual emptying.
In high humidity conditions, the internal water tank may fill up. If this occurs, the unit will stop operating and display an error code (refer to troubleshooting). Connect the provided drain hose to the drainage port and place the other end into a suitable container or floor drain to empty the water.
6.3. Storage
When storing the unit for an extended period:
- Drain any remaining water from the unit.
- Clean the air filter.
- Unplug the power cord and coil it neatly.
- Store the unit in a cool, dry place, preferably in its original packaging, away from direct sunlight and extreme temperatures.
