5.1 General notes
5.1.1 Care
The 772 Pump Unit requires appropriate care. Excess contamination of the
instrument may result in functional disruptions and a reduction in the life-
time of the sturdy mechanics and electronics.
Spilled chemicals and solvents should be removed immediately. Above all,
the plug connections on the rear 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 have pene-
trated the inside of the instrument, so as to avoid serious damage to
the instrument electronics. In such cases, Metrohm Service must be
informed.
5.1.2 Maintenance by Metrohm Service
Maintenance of the 772 Pump Unit is best carried out as part of an annual
service, which is performed by specialist personnel of the Metrohm com-
pany. If working frequently with caustic and corrosive chemicals, a shorter
maintenance interval could be necessary.
Metrohm Service offers every form of technical advice for maintenance
and service of all Metrohm instruments.
