4. Setup
- Initial Cleaning: Before first use, disassemble the bottle by unscrewing the top lid and the bottom base. Clean all parts (glass body, top lid, bottom base) with warm water and the provided cleaning brush. Ensure all components are thoroughly rinsed and dried.
- Assemble the Bottle: Reattach the bottom base to the glass body. Ensure the white rubber seal on the base is properly seated and tightened to prevent leaks. Then, screw on the top lid.
- Initial Charge: Connect the USB charging cable to the charging port on the base of the bottle and to a suitable USB power source. Charge the bottle fully before its first use. A full charge typically takes 2-3 hours and provides power for approximately 15-20 electrolysis cycles.

5. Operating Instructions
- Fill with Water: Unscrew the top lid and fill the glass body with potable water. Do not overfill; leave some space at the top.
- Start Generation: Securely screw the top lid back on. Press the power button located on the base of the bottle. A blue light will illuminate, indicating that the hydrogen generation process has started.
- Electrolysis Cycle: The device will perform a 3-minute electrolysis cycle, during which hydrogen bubbles will be visible in the water.
- Enjoy Hydrogen Water: Once the cycle is complete, the blue light will turn off. Your hydrogen-rich water is now ready to drink.

6. Maintenance
Regular cleaning and proper battery care will ensure the longevity and optimal performance of your Alwa Hydrogen Water Bottle.
- Daily Cleaning: After each use, rinse the glass body and lid with warm water. For thorough cleaning, disassemble the bottle and use the provided cleaning brush to clean the inside of the glass and the base components.
- Deep Cleaning: For optimal performance and hygiene, perform a deep clean of the electrolysis plate in the base every 20 cycles (approximately every 2-3 hours of total operation). Use the cleaning brush to gently scrub the plate.
- Battery Care: To maintain battery health and extend its lifespan, it is recommended to fully charge the device after approximately 20 electrolysis cycles. If the red light flashes, it indicates a low battery and requires charging.
- Storage: When not in use for extended periods, ensure the bottle is clean, dry, and fully charged. Store in a cool, dry place.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bottle is leaking. | Rubber seal on the base is not properly seated or tightened. | Disassemble the bottle, ensure the white rubber seal on the base is correctly positioned, and tighten the base securely to the glass body. |
| Device not generating hydrogen (no bubbles, no blue light). | Low battery or device not turned on. | Charge the bottle fully. Ensure the power button is pressed firmly. |
| Red light flashing. | Low battery. | Connect the USB charging cable and charge the device until the light indicates a full charge (usually turns off or changes color). |
