No direct user interaction is required for the fan's operation once correctly installed.

7. Maintenance

• Regular Inspection: Periodically inspect the fan for any visible damage, obstructions, or excessive dust accumulation.
• Cleaning: If dust accumulates on the fan blades or housing, gently clean it using a soft, dry brush or a can of compressed air. Ensure the humidifier is unplugged before cleaning. Do not use water or liquid cleaners on the fan.
• Avoid Obstructions: Ensure that the humidifier's air vents are clear and not blocked, as this can impede airflow and affect the fan's performance.

8. Troubleshooting

• Fan Not Spinning:
  • Ensure the humidifier is properly plugged in and powered on.
  • Check the fan's 2-wire connection to the humidifier's circuit board for looseness or incorrect insertion.
  • Verify there are no physical obstructions preventing the blades from spinning.
  • If the issue persists, the fan may be faulty and require replacement.
• Unusual Noise from Fan:
  • Disconnect power and inspect the fan for any foreign objects (e.g., dust clumps, debris) caught in the blades.
  • Ensure the fan is securely mounted and not vibrating against the humidifier casing.
  • If the noise is persistent and not due to obstructions or loose mounting, the fan bearings may be worn, indicating a need for replacement.
