5 Handling and maintenance
5.1 General information
5.1.1 Care
The 873 Biodiesel Rancimat 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.
Spillages of chemicals and solvents should be cleaned up 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 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 873 Biodiesel Rancimat 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 main-
tenance interval could be necessary.
The Metrohm service department offers every form of technical advice for
maintenance and service of all Metrohm instruments.
5.2 Replacing the dust filter
The dust filter (3- 20 ) is mounted in the opening marked with Filter on the
rear of the instrument and serves for filtration of the air sucked in through
the air pump. It must be checked at periodic intervals and replaced in the
case of more intense contamination (order number: 6.2724.010).
