- The first sample is not warranted. Please operate this device strictly according to the instructions for use. If you have any questions, please consult customer service.

Warranty and Disclaimer:
Under normal use conditions, the warranty period of the product is 1 year, starting from the time the electrolyzer leaves the factory.

The following conditions are not covered by the warranty:
1. Causes of circuits and control systems themselves, failure of other electronic components, etc.
2. Substandard water quality (e.g. mineral water, tap water or other liquids is used).
3. Ion exchange resin is not used.
4. Operating the equipment in the event of water shortage (including dry burning caused by the return of oxygen from the water inlet due to unreasonable system design).
5. The power supply of the electrolyzer is unstable and mismatched (for example, the current fluctuation amplitude of the power supply is large: the fluctuation amplitude of the current under actual working conditions is large, far exceeding the rated current, and the electrolyzer will be seriously damaged).
6. The electrolyzer is connected to the positive and negative poles of the power supply reversely, resulting in burning.
7. Artificial disassembly and reassembly and its performance cannot be restored.
8. Other man-made and accidental damage or sabotage.

Instructions for use:
I. Product Design:
1. Hydrogen products should be designed with a constant current power supply that matches the voltage and current parameters of the electrolyzer, otherwise they will cause damage to the electrolyzer or the performance is not up to standard;
2. When the product is designed, the height difference between the outlet of water tank and the inlet of the electrolyzer should be greater than 10cm/3.9"; Or equipped with a circulating water pump. When setting the circulating water pump, there is no requirement for the height difference between the outlet of the water tank and the inlet of the electrolyzer;
3. The operating efficiency of the electrolyzer has a high correlation with the working temperature. Frequent low temperature start-up will cause certain damage to the electrolyzer, so the starting temperature should be fully considered in the product design. Solving this problem requires optimization in product design. On the one hand, the supply current output at power supply start-up is controlled by a built-in program. The output current gradually rises and finally stabilizes at the rated operating current (the parameters should be consistent with the relevant model). During this period, the working voltage does not exceed the rated voltage; On the other hand, an automatic instantaneous heating module or water tank heating module should be set between the outlet of the water tank and the inlet of the electrolyzer to ensure that the water temperature flowing into the electrolyzer is not less than 25°C;
4. In order to ensure the long-term stable operation of the electrolyzer, it is recommended to equip the product with an ion exchange resin filtration device when designing. It can be set between the outlet of the water tank and the inlet of the electrolyzer to ensure that the electrolyzed water meets the use standard;
5. If the electrolyzer reuses the circulating water from the oxygen port, it is recommended to use the circulating water after ion exchange resin treatment (conductivity< 5uS/cm). It is recommended to add an ion exchange resin filter;
6. The internal space should be reasonably designed when designing the product, especially there is enough space around the electrolyzer, and the appropriate flow channel design should designed to ensure normal air flow to achieve a good heat dissipation effect;
7. The size of the water tank should correspond to the technical data table. Level control and alarm devices should be set in the water tank to ensure that the water storage is above the minimum liquid level (refer to the technical data table for specific values).

II. Product Assembly Process:
1. In the process of product assembly, it is necessary to fully understand the working principle and characteristics of the electrolyzer, prevent the joints and nozzles of the electrolyzer from being contaminated by other substances, and keep your assembly workshop clean;
2. When connecting the circuit system, carefully distinguish the positive and negative electrodes of the electrolyzer to prevent reverse connection, because reverse connection will cause the electrolyzer to be burned;
3. Pipeline connection should be stable and reliable, with suitable temperature resistance, pressure resistance and hydrolysis resistance to prevent leakage caused by aging or falling off; Materials that come into contact with water must be resistant to corrosion, oxidation and high temperatures. Users who must use metal materials are recommended to use pure titanium.
4. Electrical components should be strictly selected to ensure safety. Adopt a reasonable connection process to reduce unnecessary overheating. The quality of the connection wire between the power supply and the electrolyzer should be ensured. The connection end must be tightened in a reliable way, otherwise a large amount of heat will be generated, resulting in potential safety hazards.

III. Conditions of Use and Common Sense:
- Customers should write accurate and comprehensive product manuals to ensure that users can use the products correctly and reasonably in accordance with the instructions;
- Purified/deionized/secondary distilled water (conductivity <5uS/cm) must be used and C'estbon purified water is recommended;
- Customers must be reminded to pay attention to the water level, and it is strictly forbidden to operate with water shortage to prevent the electrolyzer from burning.
- A PEM electrolyzer is a device that requires specific conditions to function properly. Reasonable design, matching, process and use can greatly extend the service life of the device. High-quality hydrogen products can be used for 3-5 years.
