5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your Acekool Mini Split AC system. Always disconnect power before performing any maintenance.
Cleaning the Unit:
- Power Off: Before cleaning, shut down the machine and cut off the power supply for more than 5 minutes.

- Avoid Water Flushing: Under no circumstances should the air conditioner be flushed with water.
Filter Screen Maintenance:
Pay attention to cleaning the filter screen regularly to avoid dust accumulation, which can affect the filter's effectiveness and airflow. If the operating environment is dusty, increase the cleaning frequency appropriately.
- Removal: Carefully remove the filter screen according to the instructions in the full user manual.

Defrost Cycle:
In heating operation, the appliance can automatically activate a defrost cycle. This is essential to clean frost on the condenser and recover its heat exchange function.
- Automatic Defrost: This procedure usually lasts for 2-10 minutes. During defrosting, the indoor unit fan will stop operation. After defrosting, it resumes to HEATING mode automatically.
- Forced Defrosting: If necessary, you can initiate a forced defrosting cycle by pressing the ECO button 10 times within 8 seconds under heating mode. This will defrost the outdoor ice much faster.
