2. Leave the vacuum supply line connected and the vacuum source turned on.
3. Switch off the AC power switch on the Echo Liquid Handler.

Note: If the Echo Liquid Handler is going to be shut down for longer than a week, start up and run the pump once
a week to keep the acoustic transducer wet. For more information, see Extended Non-Use and Storage.
