Powering Down The System - Waters 600e User Manual

Operation
The Gradient Controller provides storage for 15 sets of tables. Each set of tables consists
of a gradient table and an event table that run together during gradient operation. The
gradient and event tables can each contain a maximum of 15 operational steps.
You can program separate tables to:
• Equilibrate the system
• Change over eluent
• Automatically purge and shutdown the system
• Lower the system flow rate after an analysis
At its completion, you can program a table to initiate the start of another table. You can
also link a table back to itself to cause a method to repeat.

2.5 Powering Down the System

If you do not plan to use the Waters 600E system for a long period of time (overnight or
longer), power down the system.
Before You Power Down
Observe these precautions before powering down your system:
• To prevent microbial growth, do not leave water or buffers in the fluidic lines while
the system is not in use.
• Flush the lines with high-purity filtered water (such as that provided by
reverse-osmosis/ion-exchange water systems), followed by an aqueous 10%
methanol solution.
• Remove the column if it is incompatible with this storage protocol.
Turn off the Waters 600E by pressing the On/Off switch on the front panel of the
controller to the 0 (Off) position.
