General preparations
Run the script: B05 - Shutdown (Long-term) with the following parameter: Module to remove = Pump.
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.
Move the system stack into an appropriate working position.
Shutdown
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.
Disconnect the power cord.
Disconnect all signal cables to other devices.
Flow connections
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.
