4.4 Care and maintenance
4.4.1 Care
The 853 CO
2
Suppressor requires adequate care. If it becomes excessi-
vely dirty then this could interfere with its functions and shorten the
working life of its robust mechanism and electronics.
Spilt chemicals and solvents must be wiped up immediately. The elec-
trical connections on the rear panel of the instrument (the mains con-
nection in particular) should be protected against contamination.
Although constructive measures to a large extent prevent liquid pene-
tration, if aggressive media should nevertheless penetrate the interior
of the instrument then the mains plug of the external 6.2152.020
Power supply should be pulled out immediately to prevent serious
damage to electronic components. If such damage should occur
please contact Metrohm Service.
The instrument should only be opened by specialists from Metrohm.
