1. The external power supply of the equipment is three-phase, four-wire 380V. If it is not connected to the zero line, the machine will not work, and the lack of phase operation will damage the equipment.

2, the use of pure water, long-term use of no filtered tap water may block the pipeline, it is recommended to use pure water can prolong the service life of the machine.

3, working environment temperature 0-40℃, good ventilation, prohibited in a closed environment.

4, the equipment requires that the external power grid has good lightning protection effect, otherwise the power should be shut down and cut off when lightning strikes.

5, the equipment is strictly prohibited from washing with water, only clean the dust in the machine with clean cloth or compressed air.

If the sensitive parts such as eyes should be washed with water and then seek medical treatment immediately. Therefore, the user should be ready to several bottles of vinegar, in case of emergency.

How to maintain hydrogen production equipment to prolong its service life:

1. Under normal circumstances, the electrolyte in the equipment shall be released to replace the new liquid after use every six months. If it works normally (gas production does not change), it is maintained once a year.

2. Check regularly whether the pipe joint in the equipment is loose or leaky.

3, often use dry compressed air to clean the electrolytic power supply and equipment.
