3.2.2. The Hardware Management Window
Prime and LM Shutdown can be executed in this window. Prime and LM Shutdown can be executed in this
window. An LM Shutdown must be carried out after the last measurement has been run and before shutting
down the Cedex HiRes Software 2.2. The Liquid Management system is then prepared for an extended pause,
i.e. overnight or weekend.
An LM Shutdown is automatically preceded by a Standard Clean routine. The 8-way valve is then rinsed with
distilled or de-ionized water to prevent crystallization, and compressed air fi nally presses the Trypan Blue
solution back into its container (see “
Carrying out an LM Shutdown and HW Shutdown”).
3.2.3. Carrying out a Cleaning Routine
The different cleaning routines always have the same starting procedure. Ensure that there is always a Cedex
Sample Cup attached to the single sample port or a Cedex Sample Cup placed in the DefaultCup position of
the Multi Sample tray.
Follow the instructions below:
1
Click on the Clean button in the Shortcuts area of the Control Center or else select Cleaning Routines
in the Functions menu. The Cleaning window will open.
2
Click on the appropriate button (e.g. Fast Clean) to automatically start the cleaning routine.
■
The Cedex HiRes Analyzer is blocked during the cleaning routine, and the duration is continuously displayed
in the Estimated Total Time fi eld.
3.2.4. Interrupting/Terminating a Cleaning Routine
Use the EMERGENCY STOP button to interrupt the cleaning routine immediately if any leaks are detected in
the Liquid Management system, even in the case of an Ultra Fast Clean being carried out automatically.
The Intensive Clean procedure can be interrupted to shorten the long detergent phase in the fl ow chamber.
Click on the Cancel button, which is only activated during the long detergent phase, in the Liquid Management
window.
3.3 Scanning the Chamber to Verify the Effectiveness of Cleaning Routines
The complete fl ow chamber can be scanned using the Scan button in the Cleaning window. Using this, the
success of the cleaning can be verifi ed after a cleaning routine.
Proceed as follows:
1
Click on the Clean button on the Cedex Control Center to open the Cleaning window.
2
Click on the Scan button in the lower right-hand corner of the Cleaning window. The fl ow chamber will
be scanned, i.e. an image of the entire chamber will be created. This process can take 1 – 2 minutes during
which the estimated time is displayed in form of a progression bar.
