5.4 Rebuilding the Injection Valve or Auxiliary Valve
Dionex recommends rebuilding the injection valve and the auxiliary valve (if
installed) annually. The Injection Valve Rebuild Kit (P/N 057896) contains all
required replacement parts for one valve.
NOTE If you prefer, you can replace the auxiliary valve “pod,”
instead of rebuilding the valve. Replacing the pod is
easier and faster than rebuilding the auxiliary valve. For
instructions, see Section 5.5
.
1. Turn off the pump from the ICS-2100 Control panel in Chromeleon or from
the touch screen
HOME page.
2. Open the ICS-2100 front door.
3. Disconnect each liquid line connected to the valve.
4. Follow the instructions provided in the Rebuild Kit to replace the rotor seal,
isolation seal, and stator face.
5. Reconnect all liquid lines to the injection valve (see Figure 5-10
) or auxiliary
valve.
6. Close the door.
7. Turn on the pump.
Substituting non-Dionex parts may impair performance, thereby
voiding the product warranty. Refer to the warranty statement in the
Dionex Terms and Conditions for more information.
