Output Characteristics:
- Normal working voltage/current: 10.2 - 14.1V/33A
- Surface temperature: <60℃
- Theoretical water consumption: about 1.2ml/min (Note: Every 1L of water produces 0.111kg of hydrogen and 0.889kg of oxygen, with a hydrogen density of 0.089kg/m³ and an oxygen density of 1.429kg/m³.)

Environment Requirements:
- Working temperature: 15℃ to 40℃
- Storage temperature: 0℃ to 40℃
- Relative humidity: 5% - 85%
- Altitude: ≤3000m
- Cooling method: fan cooling
- Life time:
  Method 1: Circulating water supply within an electrical density of 1A/cm² and a water quality of 1ppm. Power on for 60 minutes - power off for 30 minutes, with a total operating time of 5000h.
  Method 2: Circulating water supply within an electrical density of 0.625A/cm² and a water quality of less than 1ppm, working continuously for 1000 hours.
  Judgment: The working voltage of a single electrode group is within 2.35V, and it can work normally in a constant current state with continuous and stable output.
- Waterproof level: non-waterproof
- Electrical safety: the power supply is DC low-voltage weak current input, with no risk of electric shock.
- Safety distance: The surface temperature of products that have been working for a long time is relatively high, and they must be at least 3cm away from plastic parts. Products with poor ventilation must be cooled by air cooling.
- Water pressure resistance: it can withstand a maximum working water pressure of 0.5MPa and a maximum burst pressure of 1.0MPa

Package Included:
- 1 x Electrolytic Cell Module

Connection Explanation:
- 1/4" quick connectors are standard for inlet and outlet connectors: If the inlet and outlet connectors do not use the standard quick connectors, a 1/8" NPT threaded connector can be selected.
- The power input wire must use composite specification pure copper core wire, and be wired according to the positive/negative pole identification. It must not be reversed, as reversing may burn the electrode; M4 or M5 screws/nuts/washers can be used for wiring, and they must be firmly fixed, otherwise there is a risk of sparking and catching fire.

Mounting:
- The product can be directly fixed and installed.
- To ensure the water level in the electrolytic cell, the product must be installed vertically, with the inlet located below and the outlet located above.
- The electrolytic cell must be placed under the water tank, with a water level difference of 15cm at the inlet, and the return pipe should not be lower than the inlet pipe. If a circulating pump is used for water supply, the pressure after the pump should not exceed 0.5MPa.
- The product will generate high temperatures during operation, and appropriate ventilation space should be maintained. It is not allowed to directly contact plastic parts, and a fan should be used for air cooling if necessary.

Precaution:
- Water supply source: pure water in accordance with GB19298-2014, and a mixed bed resin filter with positive and negative ions must be connected to the water supply outlet to ensure that the water quality input into the electrolytic cell meets the working requirements.
- When using, ensure that the electrolytic cell is fully soaked in water before powering on to avoid damaging the membrane components due to water shortage. Water shortage will damage the electrodes.
- Water supply pressure requirements: It is recommended to use a circulating pump for water supply. For small-sized electrolytic cells (within 300m), if gravity flow water supply is used, it is recommended to have a liquid level difference of about 15cm between the water supply tank and the inlet, and ensure smooth water supply through pipelines.
- Water supply system monitoring: Water supply sources must undergo water shortage and quality monitoring, such as water level sensors in water tanks, water flow sensors in water supply pipelines, and water quality sensors in water supply pipelines, to prevent water shortage, dry burning, or substandard water quality issues.
- If there is icing during the storage and transportation process, it must be placed in a warm room before use, until it is confirmed that the ice in the electrolytic cell and pipeline has completely thawed before being powered on for use. If it is an outdoor equipment, temperature control and monitoring must be adopted to ensure that the pipeline does not freeze.
- If the electrolytic cell has not been used for more than 6 months, it is recommended to perform activation treatment before installation.
- Power parameters must meet the requirements of section 3.1: For large-sized electrolytic cells with a working current of 20A or more, it is recommended to adopt a soft start gradually increasing current working mode to reduce impact and effectively protect the electrolytic cell and power supply.
- Note that the +/- pole of the power input should not be reversed, and the wiring should be firm.
