7. Reinstall the valve assembly and reconnect all liquid lines.

8. Turn on the power to the Dionex AS-DV.

Replacing a High-Pressure Valve Pod

This procedure describes how to replace the mechanical parts (the “pod”) of an
optional high-pressure valve.

NOTE Substitution of non-Dionex/Thermo Scientific parts may

impair valve performance and void the product
warranty.

The following tool is needed to complete this procedure: 3-mm Allen wrench.

1. Turn off the Dionex AS-DV power.

2. Raise the top cover.

3. Remove the Dionex AS-DV front cover by gripping the indentations at each

side and pulling the cover straight off toward you.

4. Disconnect each liquid line connected to the valve.

The Dionex AS-DV power must be turned off before you replace a
valve pod. If the power is on when you disconnect or connect the
valve cable, the Dionex AS-DV may be damaged.
