843 Pump Station with Membrane Pumps
5 Handling and maintenance
5.1 General information
5.1.1 Care
The 843 Pump Station requires appropriate care. Excess contamination of
the instrument may result in functional disruptions and a reduction in the
service life of the sturdy mechanics and electronics.
Spilled chemicals and solvents must be removed without delay. Above all,
the plug connections on the rear panel of the instrument (in particular the
mains connection socket) should be protected from contamination.
Caution
Although this is extensively prevented by design measures, the mains
plug should be unplugged immediately if aggressive media has penetra-
ted the inside of the instrument, so as to avoid serious damage to the
instrument electronics. In such cases, the Metrohm Service must be
informed.
5.1.2 Maintenance by Metrohm Service
Maintenance of the 843 Pump Station is carried out as part of an annual
service, which is performed by technicians of the Metrohm company. If
working frequently with caustic and corrosive chemicals, a shorter mainte-
nance interval could be necessary.
The Metrohm service department offers every form of technical advice for
maintenance and service of all Metrohm instruments.
