5. Maintenance
- Moisture Management: Due to the airtight seal, moisture can accumulate inside, especially in humid environments. To prevent this, ventilate the box regularly by opening it for a few hours.
- Silica Gel: It is recommended to place silica gel bags inside the box to absorb moisture and prevent odors. Replace these bags regularly as they become saturated.
- Cleaning: Wipe the exterior with a damp cloth. Do not use abrasive cleaners or solvents. Ensure the sealing gasket is clean and free of debris to maintain its effectiveness.
6. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Moisture inside the box | Airtight seal trapping humidity; high ambient humidity. | Regularly ventilate the box. Use and replace silica gel bags. Store in a less humid environment if possible. |
| Lid difficult to close/seal | Items obstructing the seal; debris on the gasket; lid not aligned correctly. | Ensure no items are blocking the seal. Clean the gasket. Align the lid properly before closing and applying firm pressure to engage the twist lock. |
| Lock mechanism feels stiff | Lack of lubrication; minor misalignment. | Apply a small amount of graphite lubricant to the key and lock cylinder. Ensure the key is fully inserted and turned smoothly. |
