5.3 Servicing and Maintenance
5.3.1 Servicing
The maintenance of the 730 Sample Changer should include a
yearly service check carried out by a specialist from Metrohm. If
caustic or corrosive chemicals are frequently used, shorter time
intervals between service checks can be necessary.
The Metrohm Service Department can offer technical advice re-
garding servicing and maintenance of all Metrohm instruments at
any time.
5.3.2 Maintenance / Attendance
Not only do highly sensitive measuring instruments require proper
care, a sample changer also requires this. Serious contaminations
can lead to functional disorders and a shortened life-span of the
rugged mechanics and electronics of the sample changer.
Heavy soiling of the titration heads can influence the results of
measurements. Regular cleaning of exposed parts can prevent
this for the most part.
Chemical or solvent spills should be cleaned up immediately. The
connectors (in particular the power supply) should be protected
from contamination. The sample changer should never be oper-
ated without the covering foreseen for this purpose.
If corrosive media has entered the inside of the instrument, the
power plug has to be disconnected immediately to avoid massive
damage to the instruments electronic components. In case of such
damage, the Metrohm service personnel should be notified.
The instrument should not be opened by untrained personnel.
