1. Add water indicator (Add Water) light (accompanied by a warning buzzer sound), and open the top cover of the machine, add water, add water outlet from the water to the sub-tank, add water until the light goes out or fill the reserve tank so far. If automatic water through external sources, the system will automatically open the solenoid valve from an external water source water to the sub-tank, fill up to the specified location, make sure external sources of water and there is a certain pressure.

2. The lack of water indicator (Lack Water) lights up, the main water tank. Wait for automatic replenishment from the sub tank to the main tank (about 0.5 minutes).

3. Over-temperature indicator light (Over Temperature): Description The last time the machine is running, the cell over-temperature protection, there is no cooling down, continue to wait until this fault LED is off.

4. Overvoltage indicator light (Over Pressure): Description when the last shutdown, I do not let go of the gas, you should turn on the gas equipment valves, let go more than a part of the air, or in the next operation (set electrolysis current), the host current setting is not displayed on the panel, but the load current.

5. The pump operation indicator light (Pump Runing): indicates that the machine is water-resistant to the main tank or cupping, and is normal. Pump running lights of time should not exceed 3 minutes, as more than three minutes, then it is abnormal, it may cause is vice-water tank, resulting in high pressure diaphragm pump is less than the reserve tank in the water, unable to complete the replenishment requirements, so pump has been running, trying to water in the tank pumped deputy.
