Collecting vessel and hoses between the solenoid valve and collecting vessel
The automatic cleaning function of the Liquiline System CAT860 comprises the filter and
practically all the hoses. The collecting vessel and the hose between the solenoid valve and
collecting vessel do not fall within the scope of the automatic cleaning function. This excludes
the possibility of the measurement result being affected by the cleaning solution. Therefore, the
collecting vessel and the hose between the solenoid valve and collecting vessel must be cleaned
manually on a regular basis. The cleaning interval in a typical application is 1 week.
