5.1 General notes
5.1.1 Care
The 823 Membrane Pump Unit requires appropriate care. Excess contami-
nation of the instrument may result in functional disruptions and a reduc-
tion in the lifetime 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 823 Membrane Pump Unit is best carried out as part
of an annual service, which is performed by specialist personnel of the
Metrohm company. 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.
