2. Safety Information
Always observe the following safety precautions to prevent injury or damage to the device:
- Ensure the machine is placed on a stable, level surface away from direct sunlight, heat sources, and flammable materials.
- Use only purified water or distilled water with a TDS (Total Dissolved Solids) level below 3ppm. Using tap water or mineral water can damage the electrolysis module.
- Do not block the ventilation openings on the machine. Ensure adequate air circulation around the unit.
- Keep the machine out of reach of children and pets.
- Do not disassemble or attempt to repair the machine yourself. Contact qualified service personnel for assistance.
- Unplug the power cord before cleaning or performing any maintenance.
- Avoid operating the machine in excessively humid environments.
- If you experience any unusual odors, sounds, or malfunctions, immediately turn off the machine and unplug it.
3. Product Components

4. Setup Instructions
Follow these steps to set up your hydrogen machine:
- Unpack the Machine: Carefully remove the machine and all accessories from the packaging.
- Placement: Place the machine on a firm, flat, and stable surface. Ensure there is sufficient space around the unit for ventilation. The machine is equipped with wheels for easy movement.
- Fill with Water: Locate the water tank inlet. Fill the tank with purified or distilled water (TDS < 3ppm) up to the maximum fill line. The machine has a 9.6-liter capacity.
- Install Filter Element: Insert the provided filter element according to the instructions in the filter compartment.
- Connect Power: Plug the power cord into the machine's power inlet, then plug the other end into a suitable electrical outlet (220V/50HZ).
- Attach Inhalation Accessories: Connect the nasal inhalers to the transfer takeovers, and then connect the takeovers to the machine's hydrogen outlets. Use the Y-type connector if two users will inhale simultaneously from a single outlet, or connect directly to the three independent outlets.

5. Operating Instructions
The machine features a touch screen LCD display for easy control.
- Power On: Press the power button on the control panel. The LCD display will illuminate, showing real-time monitoring information.
- Adjust Flow Rate: The machine offers three adjustable air volume levels: 1500ML/min, 2250ML/min, and 3000ML/min. Use the controls on the touch screen to select your desired flow rate.
- Start Inhalation: Once the desired flow rate is set, place the nasal inhaler comfortably into your nostrils. The machine will begin producing hydrogen.
- Monitor Display: The display shows hydrogen purity (99.99%), current flow rate, and accumulated usage time.
- Intelligent Shutdown: The machine features an intelligent shutdown function. Refer to the display for timer settings or manual shutdown.
- Multiple Users: The three-outlet design allows for independent hydrogen/oxygen output, enabling up to two people to inhale hydrogen simultaneously.
