11.1 Cleaning Options
It is also recommended to use MCU or the Automatic Cell Cleaning device to clean the
Measuring Cell.
Cleaning of the Sample Glass Tube could be simplified with a MCU or an Automatic Cell
Cleaning Device.
Using the Manual Cell Cleaning Unit MCU:
Ensure that there is a clean water supply through the cell.
Activate the Manual Cleaning Unit by gently pressing the handle several times.
Each time the handle is pressed, the wiper goes through the Sample Glass Tube
once.
Check, that the reading is between 0 to 2 ppm.
Additional conventional cleaning with the Cell Cleaning Brush may be necessary.
The MCU may also be used during operation with sample water. An alarm may
occur, because the wiper is passing the light source.
Using the Automatic Cell Cleaning Device:
The Automatic Cell Cleaning Device can be set to cleaning intervals from a minimum of 1
minute to maximum of 8 hours (See 21.2.2 Functional Button “ON”). This cleaning
sequence can be set from the display at all time. Even if the cleaning interval has been
set before and is not finished.
i
It is recommended to assist the Automatic Cell Cleaning Device by manually
cleaning the Sample Glass Tube at regular maintenance schedule, or as necessary.
If the Measuring Cell is equipped with a Cell Cap, please refer to section 12.
Operator Maintenance.
