5.4 Rebuilding the Injection Valve or Auxiliary Valve
Thermo Fisher Scientific 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 Dionex ICS-1100 Control panel in Chromeleon.
2. Open the Dionex ICS-1100 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 5-4
) or auxiliary
valve.
6. Close the door.
7. Turn on the pump.
Substituting non-Dionex/Thermo Fisher Scientific parts may impair
performance, thereby voiding the product warranty. Refer to the
warranty statement in the Dionex Terms and Conditions for more
information.
