，
We recommended to use purified water, and the water temperature is
controlled at below 35 ℃. If exceed 35 ℃, it need to replace the circulating water or add ice
cubes to the water to reduce the temperature（It recommends that users choose chiller, or use
Clean water tank (water change)：firstly off the power，Unplug the tube inlets,，let the laser
