Important Safety Precautions

To ensure safe operation and prevent injury or damage, please read and follow these precautions:

• Do not overfill the mug. Leave adequate space to prevent spills when closing the lid.
• Keep out of reach of children, especially when the mug contains hot liquids, to prevent burns.
• Do not place the mug in a microwave oven, conventional oven, or on direct heat sources. This can damage the vacuum insulation and pose a fire hazard.
• Do not use for carbonated beverages or dry ice, as pressure buildup can cause the lid to eject forcefully.
• Ensure the lid is securely closed and all gaskets are properly seated to prevent leaks.
• Avoid dropping the mug or subjecting it to strong impacts, which can compromise its insulation performance.
• Do not drink directly from the mug while driving or engaging in activities that require full attention.

Setup

1. Unpacking: Carefully remove the mug and all its components from the packaging. Retain the packaging for future storage or transport if desired.
2. Initial Cleaning: Before first use, wash all parts (mug body, lid assembly) thoroughly with warm water and mild dish soap. Rinse well and allow to air dry completely. Refer to the 'Maintenance' section for detailed cleaning instructions.

Operating Instructions

1. Pre-heating/Pre-cooling (Optional): For optimal temperature retention, pre-heat the mug with hot water or pre-cool with cold water for 5-10 minutes before filling with your desired beverage. Empty the pre-heating/pre-cooling water before proceeding.
2. Filling the Mug: Pour your hot or cold beverage into the mug. Do not fill past the bottom edge of the lid threads to prevent overflow.
3. Securing the Lid: Place the lid assembly onto the mug body and twist clockwise until it is firmly tightened. Ensure the lid is properly aligned and sealed to prevent leaks and maintain temperature.
4. Drinking from the Mug: To drink, simply unscrew the entire lid assembly. The mug does not feature a push-button or flip-top drinking spout.

Maintenance and Cleaning

Regular cleaning is essential for hygiene and to maintain the mug's performance. Always clean the mug after each use.

1. Disassembly: Unscrew the lid from the mug body. Carefully disassemble the lid components (stopper, gaskets) as shown in the parts identification image.
2. Washing:
   • Mug Body: Wash the interior and exterior with warm water and mild dish soap using a soft sponge or brush. The non-stick interior is designed for easy cleaning.
   • Lid Components: Wash all disassembled lid parts thoroughly with warm water and mild dish soap. Pay close attention to gaskets and crevices to remove any residue.
3. Rinsing: Rinse all parts thoroughly with clean water to remove all soap residue.
4. Drying: Allow all parts to air dry completely before reassembling. This prevents mold and odors. Do not use a dishwasher for any components, as this can damage the lid's coating and gaskets.
5. Reassembly: Once dry, carefully reassemble the lid components, ensuring all gaskets are correctly positioned.

Troubleshooting

• Leakage: If the mug leaks, ensure the lid is tightened securely and all gaskets within the lid assembly are properly seated and free from damage or debris.
• Poor Temperature Retention: Verify that the lid is fully sealed. Ensure the mug was pre-heated or pre-cooled if desired. Extreme ambient temperatures can also affect retention.
• Unpleasant Odors: Thoroughly clean all parts, especially the lid components and gaskets, as residue from beverages can cause odors. A mixture of baking soda and water can be used for stubborn odors, followed by a thorough rinse.
