b. Under Installed Options, verify that the Degas check box is selected.
c. Under Degas Mode, verify that the Always Off option is not selected. If
it is, select one of the following settings:
• Cycle, and select On: 30 seconds and Off: 10 minutes
• Monitor
d. If the Degas Mode settings are correct, but the degas assembly still does
not run, test the assembly by selecting the Always On option. The pump
should turn on immediately. If it does not, the vacuum degas assembly
may need to be replaced. Contact Dionex for assistance.
e. If the degas pump runs when you select Always On, but does not run
when Monitor mode is selected, recalibrate the degas assembly (see
Section 5.1.4
).
Select the Degas Mode, Always On option only when testing the vacuum
degas assembly. Do not select the Always On option for routine use.
