5 MAINTENANCE AND SERVICE
To ensure long-term functioning of the analyser, it is necessary to clean the
measuring-chamber and replace worn parts from time to time depending on
the frequency of analyses and general pollution levels. Depending on the
load of the appliance, maintenance work should be done at intervals of
about 6 months.
Maintenance is easy to perform. We recommend that the maintenance is
performed by trained personnel. Always observe the following safety
