Operation TresCon UNO

5.8 Valve control
General If the TresCon UNO is operated without sample filtration (e.g. PurCon),
sediments may collect in the overflow vessel. We recommend to use
the overflow vessel with the TC/ ÜB V controllable valve (accessory).
Thus the overflow vessel is emptied automatically; the sediments are
removed.
Note
How to install the TC/ ÜB V overflow vessel with valve is described in
section 3.6.2 from page 3-24.
Note
We recommed to adjust the opening time and interval to the settings of
AutoCal and AutoClean. Thus, a lack of sample cannot occur during
the opening. The valves always open for 5 seconds.
