6. Installation Guidelines and Use Precautions

6.1 Installation Guidelines

1. Surface Preparation: Clean the trough thoroughly to remove dust, debris, and residues.

2. Positioning: Align the U-shaped liner carefully in the trough.

3. Securing the Liner: Use appropriate brackets, clips, or fasteners to ensure a tight and secure fit.

4. Final Inspection: Verify even placement to prevent gaps and ensure smooth material flow.

6.2 Use Precautions

• Avoid exceeding recommended load limits to prevent liner deformation.

• Monitor conveyor operation for unusual vibrations or noise, which may indicate improper installation.

• Avoid direct exposure to temperatures beyond the specified operating range (-40°C to 80°C).

• Regularly inspect liners for abrasion, cracks, or chemical damage.

7. Storage and Handling Conditions

Proper storage and handling are crucial for maintaining the integrity and longevity of the liner:

• Storage Environment: Keep in a cool, dry, and shaded location, away from direct sunlight.

• Stacking: Store flat and not exceeding recommended stacking height to avoid deformation.

• Handling: Avoid dragging or dropping; handle with care to prevent surface scratches or impact damage.

• Shelf Life: When stored properly, the liner maintains performance for 5–10 years.
