Functions:

1) Automatically and manually wash RO membrane.
2) Manually wash RO memebrane with chemicals on machine.
3) Machine automatically stops when high water level of purified water, and runs when low level.
4) Multi-stage pumps protect the machine when lack of water.
5) Protection in such cases as no power, lower pressure, higher pressure, shot circuit, creepage, etc.
6) Large eletric current, creepage protect and so on.
