To start up the system:
1. From the system view of the console, click Control > Start up system.
Alternative: Right-click in the control panel and click Start up system.
2. On the Prime Solvents tab, click the solvent manager sub-tab and if necessary, change
the value in the Duration of Prime field.
Notes:
• If you are priming with solvents that differ significantly from the current solvents, prime
the solvent manager for minimum of 5 minutes.
• If you are using a concentrated acid and a concentrated base, it is recommended that
the lines are not primed in succession. Instead, to reduce the risk of salt formation,
ensure the pump is flushed or primed with water prior to priming the second buffer.
• If you want to return settings to their original values on any tab, click Set Defaults.
3. On the Prime Solvents tab, click the sample manager sub-tab and if necessary, change
the settings for the wash and purge solvent.
