For non-continuous operation with cooling by supply line water (individual meas-
urements separated by relatively long interruptions) a stabilizer must be added to
the water circuit to prevent the formation of algae (Aqua-Pro), especially if the de-
vice will not be used for long periods of time.
To do this, start a measurement without placing a sample in the decomposition ves-
sel and then manually activate the &DQFHO function key during the preliminary ex-
periment (after filling the inner vessel).
The measuring cell cover opens and the water is pumped in the inner vessel.
While the water is being pumped out, add about 4 ml of Aqua-Pro to the inner ves-
sel.

connection.

Instructions.
