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 immediately. Above all, the
plug connections on the rear of the instrument (in particular the mains con-
nection 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 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.

5.1.2

Maintenance by Metrohm Service

Maintenance of the 843 Pump Station is best 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.

Pump

Caution

The Pump Station must be switched off immediately with the Emergency
Stop switch if the peristaltic pump becomes blocked. If this is not done,
then the pump could suffer damage from overheating.
