Maintenance:

1. Cleaning: After each use, empty the ice box and wash the interior and exterior with a mild soap and warm water solution. Clean the lock mechanism gently.
2. Rinsing: Rinse thoroughly with clean water to remove all soap residue, ensuring no water enters the lock mechanism.
3. Drying: Allow the ice box to air dry completely with the lid open to prevent moisture buildup and odor formation. Ensure the lock mechanism is also dry before storing.
4. Storage: Store the clean, dry ice box in a cool, dry place away from direct sunlight and extreme temperatures. Storing it with the lid slightly ajar can improve air circulation.

Precautionary Guidance:

• Avoid Overloading: Do not exceed the stated capacity, as this can strain the structure and compromise insulation and the locking mechanism. Be mindful of the increased weight when fully loaded.
• Secure Lid and Lock During Transport: Always ensure the lid is properly latched and the single lock is engaged before and during transport to prevent accidental opening and loss of cold contents, as well as to ensure the security of the contents.
• Minimize Exposure to Extreme Heat: While insulated, prolonged exposure to intense heat can reduce cooling efficiency and potentially affect the integrity of the lock.
• Use Caution with Dry Ice: If using dry ice for enhanced cooling, ensure adequate ventilation to prevent the accumulation of carbon dioxide gas. Follow established safety guidelines for dry ice handling. Be mindful of potential pressure buildup that could affect the lid and lock.
• Handle with Care: While robust, avoid dropping the ice box or subjecting it to significant impacts that could cause damage to the structure or the locking mechanism. Be extra cautious due to the larger size and potential weight when full.
• Use for Cold Items Only: This ice box is designed for maintaining the temperature of cold items. Introducing hot items can damage the insulation and the plastic material.  
• Maintain the Lock: Avoid forcing the lock and ensure it is free of debris for smooth operation. If the lock becomes stiff, a small amount of silicone-based lubricant may be used.
