General preparations

  1. Run the script: B05 - Shutdown (Long-term) with the following parameter: Module to remove = Pump.

  2. To be able to shift the system base slightly on the workbench for better access to system parts, unlock the system base using the system base locking tools. See Unlocking the System Base.

  3. Move the system stack into an appropriate working position.

Shutdown

  1. Turn off all system modules with their main power switch. Pressing the system power button will not be sufficient to turn off the power to the devices completely.

  2. Disconnect the power cord.

  3. Disconnect all signal cables to other devices.

Flow connections

  1. Remove all flow connections to other system modules:

    • Seal wash pump inlet line from the peristaltic tubing on the seal wash pump

    • Needle wash lines (labeled W and S) from the degasser ports

    • Capillary to autosampler from the pump outlet port

    • Solvent lines from the pump inlet ports

NOTICE

Flow connections and capillary connectors are highly sensitive to contamination. Dust and debris can contaminate these connections.

Always install caps onto capillaries and plugs to open flow connections to protect them from contamination.

  1. Close open flow connections with appropriate plugs, for example, the plugs from the ship kit.

  2. Check the leak tray and drain port. If liquid is present, absorb the liquid with a tissue.
