5 Handling and maintenance
5.1 General information
5.1.1 Care
Warning
The instrument housing must not be opened by untrained personnel.
The instrument requires appropriate care. Excess contamination of the
instrument may result in functional disruptions and a reduction in the serv-
ice life of the sturdy mechanics and electronics.
Caution
Although this is prevented to a great extent by design measures, the
mains plug should be unplugged immediately if aggressive media has
penetrated the inside of the instrument, so as to avoid serious damage
to the instrument electronics. In such cases, the Metrohm Service must
be informed.
Spillages of chemicals and solvents should be cleaned up immediately. In
particular, the plug connections on the rear panel of the instrument (espe-
cially the mains plug) should be protected from contamination.
5.1.2 Maintenance by Metrohm Service
Maintenance of the instrument is best carried out as part of an annual
service, which is performed by specialist personnel from Metrohm. If
working frequently with caustic and corrosive chemicals, a shorter mainte-
nance interval is recommended. The Metrohm service department offers
every form of technical advice for maintenance and service of all Metrohm
instruments.
5.1.3 Operation
Caution
In order to avoid disturbing temperature influences, the entire system
must be protected against direct sunlight.
