8 Maintenance
If you need to change your turret, use the following instructions for proper
replacement.
1 For a 5890/6890 GC with a tray:
• If you are changing from the 1-sample transfer turret to the 8-sample
turret, disable the tray.
• If you are changing from the 8-sample turret to the 1-sample transfer
turret, enable the tray.
The 5890 Series II GC uses a software program run on a PC connected to
the controller to configure the tray. Run the program, select Configuration,
and either check (to enable) or uncheck (to disable) the tray. Select Send
Settings to ALS to download the new setting to the controller.
All 6890 GCs disable the tray using the GC keypad.
2 Open the injector door. Unscrew and remove the knurled nut from the top
of the turret.
