2.2.12.2 Inspection and Troubleshooting of Valve Clogging
1. To prevent the possibility of liquid flowing onto the base plate when the tube connected to the
valve is pulled out, the tube pulled out needs to be placed into the small sample cup, and tissue
paper should be used as a pad to prop up any affected components. The sample cup should be
removed once the liquid has stopped flowing.
2. Disassemble the valve. Then open the valve cap to check if there is any clogging caused by
impurities; if so, remove the impurities.
3. See Figure 2-20 and Figure 2-21.

Figure 2-21 2-way valve (L)
4. Place the components in their original positions. (Note that the parts with instructions are kept on
the same side during installation. Then remove the tissue paper and clean the bottom.)
