5.1 Maintenance / Service
The maintenance of the 824 Easy Sample Changer should take place
within the framework of an annual service carried out by trained
Metrohm technicians. If harsh and corrosive chemicals are frequently
used then shorter maintenance intervals are necessary.
The Metrohm Service Department will provide competent advice about
the care and maintenance of all Metrohm instruments.
5.2 Care / Maintenance
Not only highly sensitive measuring instruments but also sample
changers need adequate care. Excessive contamination of the instru-
ment could interfere with its functions and reduce the working life of the
really robust mechanism and electronics of the sample changer.
Excessive contamination of the titration head can influence the results
obtained. This can largely be prevented by cleaning the exposed parts
regularly.
Spilt chemicals and solvents should be removed immediately. The con-
nections strip (and the mains connection in particular) should be pro-
tected against contamination. Never use the sample changer without
the connections cover and splash protector in position.
Although the design prevents liquid penetration to a great extent, if ag-
gressive media should enter the housing then pull out the mains plug
immediately, in order to prevent massive damage to the instrument’s
electronics. In such a case please contact your distributor's service de-
partment.
Warning
The instrument must not be opened by untrained personnel!
