General Use & Instruction For Different pH Water

The Benefits Of Hydrogen In Alkaline Water

What is Hydrogen? -----"The fuel of life."

Nobel Prize winner Albert Szent-Gyorgyi stated in his 1937 Nobel Lecture, "A living cell requires energy not only for all its functions, but also for the maintenance of its structure" ... "bring out the fact that our body really only knows one fuel, hydrogen."

[Diagram description: An atomic model showing a nucleus and an orbiting electron, labeled 'Molecular Hydrogen'. Next to it, the chemical symbol 'H' with atomic number 1 and atomic mass 1.00794, labeled 'Hydrogen'.]

Hydrogen is the smallest and lightest antioxidant.

Due to free electrons and reactive nature, hydrogen is a strong antioxidant with high reduction potential. Its small size allows it to penetrate easily through cell membranes, rejuvenating and repairing cells damaged by harmful free radicals. Antioxidants prevent cell oxidation caused by free radicals, a primary cause of diseases. Hydrogen is hundreds of times more effective than antioxidants like Vitamin C and has no side-effects. It is an inner gas produced by bacteria in the large intestine through fermentation.

[Diagram description: A comparison chart showing the antioxidant potential of various substances: Molecular Hydrogen (2), Vitamin C (176), Glutathione (309), Coenzyme Q10 (863), Catechin (290), Vitamin E (431).]

Selective powerful antioxidant ability that only targets and neutralize toxic free radicals(OH)

[Diagram description: A chemical equation showing Molecular Hydrogen (HH) plus Hydroxyl Radical (OH) equals H2O. Icons represent the antioxidant and free radical.]

H2 is extremely small and effective, reaching into cells and the brain where other antioxidants may be blocked, to neutralize free radicals and prevent damage.

How is the Hydrogen-rich water working as an antioxidant?

[Diagram description: Two illustrations. The left shows 'How the hydrogen is working as an antioxidant', depicting Hydrogen-Rich Water interacting with Harmful Oxygen and Beneficial Oxygen. The right shows 'Extracellular' and 'Intracellular' environments with Free Radicals (FR), Hydrogen (H), Vitamin C, and Vitamin E molecules interacting.]

Free radicals outside cells can be removed by polyphenols, Vitamin C, and Vitamin E. Free radicals inside cells are primarily removed by hydrogen-rich water, which penetrates cells due to its small size. The water ionizer produces Hydrogen in alkaline water during electrolysis, separating hydrogen and oxygen. Hydrogen passes through the ion membrane, maximizing dissolved hydrogen and electron concentration.

Principle of Operation

The water ionizer works by electrolysis, changing the pH and Oxidation-Reduction Potential (ORP) to separate hydrogen and hydroxide ions. Water naturally does not decompose into O2 and H2. However, with cathode and anode added and current applied, water is electrolyzed.

Anode materials are typically platinum, which are resistant to dissolution. The oxidation-reduction reactions are:

• 2H₂O + 2e⁻ = 2OH⁻ + H₂ (Alkaline electrolytic water with reductive, E₀=0-0.0591pH)
• H₂O = 2H⁺ + ½O₂ + 2e⁻ (Acidic electrolytic water with oxidative, E₀=1.228-0.0591pH)

After hydrogen and oxygen are produced, the water around the electrodes becomes alkaline and acidic, changing the ORP. A porous semipermeable membrane separates the poles, allowing selective passage. Acidic water (high concentration, oxidative) is collected from the positive pole, and alkaline water (high concentration, reductive) from the negative pole. This is the operational principle of the water ionizer.

Precautions For Use

Please read and follow these precautions carefully to avoid damage to the machine or harm to your health.

• City or municipal water is recommended. Well water or ground water containing impurities, chemicals, or heavy metals is not recommended.
• Replace water filters timely to ensure water quality for health and machine lifespan.
• Do not connect to a water heater. Ensure inlet water temperature is below 45°C (113°F). Keep the machine away from high temperatures and direct sunlight.
• Do not rinse the machine directly with water. Do not use alcohol or volatile solvents for wiping; use a soft cloth with soapy water.
• Do not use aluminum or copper containers for alkaline or acidic water, as they can contaminate the water.
• Do not disassemble the machine or components. Do not block, fold, or break the outlet tube. Ensure the drain water outlet tube is not kept in a high place when the machine is working, to allow free water expulsion. The drain water tube should be no more than 60cm in length.
• Each morning, before collecting alkaline water, run water for 10-30 seconds to flush the machine and filters. At the end of the day, flush for 10-15 seconds using "Purified water" or "Sanitizing" level to prevent scaling.
• Ionized alkaline & acidic water should be used as soon as possible, within 24 hours.
• Do not take medicine with alkaline water; use purified water instead.
• Do not drink acidic water.
• Disconnect the power plug when not using the machine for extended periods.

Troubleshooting

• Issue 1: The power supply light is not on or the LCD screen does not display.
  Solution: Check electricity power supply connection and re-plug the cord.
• Issue 2: Touch control panel does not function or respond (machine still works normally).
  Solution: Unplug the power cord, wait a minute, then plug it back in. The unit should return to normal operation. Note: Do not share the power supply with large appliances. Do not locate the ionizer near electromagnetic radiation appliances (e.g., microwave ovens).
• Issue 3: Background light on LCD is not on and the LCD is dark when water passes through.
  Solution: Tap water pressure is LOW (less than 0.8L/minute output). Increase water pressure and check if the filter is blocked. Replace filters as needed.
• Issue 4: Acidic/alkaline water or purified water does not come out.
  Solution: Replace water filters if needed. If water pressure is too low, increase it. If the "cleaning indicator" light is "ON", initiate a cleaning cycle.
• Issue 5: White sediment in alkaline water.
  Solution: Alkaline water may appear whitish due to air bubbles during production; it will clear soon. This is normal and the water is safe to drink.
• Issue 6: White film on the inner wall of the alkaline water container.
  Solution: This is calcium carbonate crystallization from gas in the air after reaction with solid calcium components. These substances are normal and do not indicate a problem with the water. The water is safe to drink. Note: If persistent, use food-grade citric acid or white vinegar to clean electrode plates, soak for a few hours, and flush thoroughly. Refer to maintenance procedures. If the machine will not be used for a long period, unplug it, remove the filter, drain thoroughly, and store the filter cartridge in a sealed bag in the refrigerator.
• Issue 7: Alkaline water output amount gradually reduces.
  Possible causes and solutions:
  
  • Inlet Water Pressure: Ensure input water pressure is sufficient (above 40 psi).
  • Filter blockage: Ensure filter life is OK and replace filters as needed.
  • Excessive calcium deposits in the outlet tube: Clean the outlet tube as needed. Soak in citric acid if necessary.
  • Excessive calcium deposits on electrolysis plates: Contact customer service for support.
