The Keter Cortina Bella storage box is designed for low maintenance, thanks to its durable EVOTECH material. Follow these simple guidelines to keep your box in excellent condition:

- Inspection: Regularly inspect the hinges, handle, and all panel connections to ensure they are secure. Tighten any loose fasteners as needed.
- Drainage: Ensure the area around the base is clear to allow for proper water drainage and prevent accumulation of moisture.
- UV Protection: The EVOTECH material is UV protected, ensuring the color and integrity are maintained over time, even with prolonged sun exposure.
7. Troubleshooting
If you encounter any issues with your Keter Cortina Bella storage box, refer to the following table for common problems and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Doors do not close or align properly. | Uneven ground; panels not fully engaged; hinges misaligned. | Ensure the box is on a perfectly level surface. Check that all wall panels are fully clicked into their grooves. Re-align hinges if necessary. |
| Water accumulation inside the box. | Improper assembly of roof or floor panel; damaged seals; extreme weather conditions. | Verify that the roof and floor panels are securely attached and all seals are intact. Ensure the box is on a surface that allows water to drain away from the base. While the box is weatherproof, extreme conditions may allow minimal ingress. |
| Handle is stiff or difficult to turn. | Debris in mechanism; misaligned doors. | Clean the handle mechanism. Check door alignment as per the first troubleshooting point. |
| Panels appear warped or damaged. | Improper handling during assembly; manufacturing defect. | If damage occurred during assembly, assess if it affects functionality. For manufacturing defects, contact Keter customer support with proof of purchase. |
