    If the sample flow rate is too small, the instrument will be in Alarm and display “Status: Flow”. On instruments fitted with Manual Cleaning Unit (OMD-2008 EV-FC MCU), sample a higher or a lower flow rate can be adjusted. To get the higher flow rate, remove the smaller O-Ring (9.5x2) from the Manual Cleaning Unit.
