Maintenance
Regular maintenance ensures optimal performance and longevity of your Acekool Mini Split AC system.
Filter Cleaning:
The unit features a detachable and easy-to-clean filter. Regularly clean the filter screen to prevent dust accumulation, which can affect efficiency.
- Frequency: Increase cleaning frequency in dusty environments.
- Procedure:
- Shut down the machine and cut off the power supply for more than 5 minutes before cleaning.
- Remove the filter screen carefully.
- Clean the filter using a soft brush or vacuum cleaner. For stubborn dirt, wash with lukewarm water and a mild detergent.
- Allow the filter to dry completely before reinserting.
- Do not touch the fins of the indoor unit after removing the filter screen to avoid scratching.

Defrost Cycle:
In heating operation, the appliance can automatically activate a defrost cycle to clean frost from the condenser and restore heat exchange function. This procedure typically lasts 2-10 minutes, during which the indoor unit fan stops. After defrosting, it automatically resumes heating mode.
For forced defrosting, press the ECO button 10 times within 8 seconds under heating mode. This will defrost outdoor ice much faster.
General Cleaning:
- Never use volatile liquids (e.g., paint thinner, benzene) as they will damage the air conditioner.
- Wipe the exterior surfaces with a soft, dry cloth. For stubborn stains, use a cloth dampened with a neutral detergent.
