5.5 Replacing an Auxiliary Valve Pod
This procedure describes how to replace the mechanical part (the “pod”) of the
optional auxiliary valve. This procedure is an alternative to rebuilding the valve
(see
Section 5.4 ).
NOTE If the valve electronics require service, contact Dionex.
Electronics-related repair procedures must be
performed by Dionex personnel.
1. Turn off the pump flow 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. Unscrew the black locking ring
on the front of the valve (see
Figure 5-11 ) and remove the
ring.
5. Grasp the front of the valve pod
and pull firmly to remove it
from the ICS-2100.
Figure 5-11. Unscrew the Valve Locking Ring
6. Check that the new pod (6-port, P/N 061947; 10-port, P/N 061948) has the
correct number of ports for the valve being serviced.
7. Align the slots in the new pod with the runner in the valve holder on the ICS-
2100 (see Figure 5-12 ). Valve pods are keyed to fit only one way (one slot is
narrower than the other). Verify that the slots are aligned with their matching
runners.
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.
