1.Evaluation

Inspect the belts for signs of wear, cracks, fraying or any other damage

Check for proper tension Belts should have a slight give when pressed with moderate force

2.Replacement

Replace any belts showing significant wear or damage advisable to replace all belts at once to ensure uniformity and prevent issues choose highly quality belts suitable for your AHU specifications to ensure longevity and reliability

3.Adjustment

Use the manufacturer guidelines to adjust the tension of the belt correctly

Overtightened belt can cause premature wear on bearing and other component

Loose belt can slip and reduce efficency

Tension adjustment may involve loosening or tightening the tensionsing mechnanism such as tensioner pulley or adjustable motor mount

4.Alignment

Ensure proper alignment of pulleys to prevent premature wear and tear on the belts

Use a straight edge or laser alignment tool to align pulley horizontally and vertically misaligned pulley can cause belts to wear unevenly and lead to vibration issues

5.Testing

After adjustments, start the AHU and observe the belts in operation

Listen for any unusal noises or vibrations that may indicate further adjustments are needed

Monitor the belts periodically, especially after initial adjustments, to ensure they maintain proper tension and alignment

6.Documentation

Keep detailed records of belt maintenance, including replacement dates, tension adjustments and any issues encountered

Note any unusual wear patterns or recurring problems for future reference
