6.3 Service and maintenance
6.3.1 Service
The 711 Liquino should be serviced once per year by authorized specialists.
If work is often carried out with corrosive chemicals it may be necessary to
arrange for shorter service intervals.
The Metrohm service department will provide you with technical advice
about the service and maintenance of all Metrohm instruments at any time.
6.3.2 Maintenance / Care
Not only highly sensitive measuring instruments but also the 711 Liquino re-
quires adequate care. An excessively dirty instrument could be subject to
functional interference and have a shorter working life. Whenever possible
avoid using the 711 Liquino in a corrosive atmosphere.
Regular cleaning, above all of the Dosinos and the dosing units, can pre-
vent possible functional interference.
Spilt chemicals and solvents should be cleaned up immediately. Great care
should be taken to protect the electrical connections from contamination.
Although the penetration of corrosive liquids is to a large extent prevented
by constructional measures, if aggressive media do penetrate the interior of
the instrument the mains plug must be pulled out immediately to prevent ex-
tensive damage to the electronic system. In such cases please inform the
Metrohm service personnel.
The instrument must not be opened by untrained personnel.
