7. Apkope

The Systemair K 125M Sileo fan is designed to be reliable and largely maintenance-free. However, periodic checks can help ensure optimal performance and longevity.

• Tīrīšana: Periodically inspect the impeller and housing for dust and debris accumulation. Clean gently with a soft brush or cloth. Ensure power is disconnected before cleaning.
• Pārbaude: Pārbaudiet elektriskos savienojumus, vai tie nav cieši pieguļoši un nav nodiluma pazīmju.
• gultņi: The fan's motor bearings are typically sealed and do not require lubrication.

8. Traucējummeklēšana

If you encounter issues with your Systemair K 125M Sileo fan, consider the following common troubleshooting steps:

• Fan not starting: Check the power supply, circuit breaker, and electrical connections. Ensure the thermal contacts have not tripped (they reset automatically).
• Samazināta gaisa plūsma: Inspect ducts for obstructions or leaks. Check if the fan speed controller is set correctly.
• Neparasts troksnis vai vibrācija: Ensure the fan is securely mounted. Check for any foreign objects in the impeller or housing. Verify that the FK connecting sleeves are properly installed if used.
• Pārkaršana: Ensure adequate ventilation around the fan. Check for obstructions that might restrict airflow. The built-in thermal contacts should protect the motor.

If problems persist after performing these checks, contact qualified service personnel or Systemair support.
