Operating procedures for laboratory-specific ultra-pure water machines

1. Check whether the stainless steel ball valve switch of the water source is turned on, whether the power cord is connected, and make sure it is turned on.

2. Press the "Power" button, at this time the indicator light of "System Water Production" is on, and it starts to work normally.

　　4. Please keep the plastic ball valve on the water storage tank in the same direction as the pipeline connection. It is open at this time. Do not close the ball valve switch. Do not twist the vacuum plug at the bottom of the water storage tank, otherwise the water storage tank will be scrapped.
　　5. Pre-preprocessor cleaning: When the instrument is used for a period of time, the white PP polymer fiber filter element starts to change from white to yellow. At this time, use a special wrench to remove the preprocessor barrel, and take out the fiber filter element with high pressure Rinse with tap water, you can tap and rinse until it is confirmed that it is rinsed clean before reinstalling. When reinstalling, check whether the plastic pad inside the barrel is well-matched, and make sure that the barrel does not leak after installation. If it leaks, remove it and check again .
