6. Maintenance

Regular maintenance ensures the longevity and efficient operation of your air conditioner. Always disconnect power before performing any maintenance.

• Clean filters every two weeks or more frequently depending on usage and air quality.

Unit Surface Cleaning:

• Wipe the indoor and outdoor unit surfaces with a soft, damp cloth.

• Ensure the drainage hose is clear and not blocked.
• Consider professional inspection and cleaning annually.

7. Troubleshooting

Before contacting service, please check the following common issues:
