6. Cleaning and Maintenance
6.1.4 SMART cleaning
The objective of the SMART cleaning is to clear reagent residue from all lines.
A SMART cleaning is necessary in the following cases:
• At regular intervals (approx. once a month and before inserting a new active carbon filter) to
clean the air system/liquid system and reduce deposits in the lines.
• For each change of the station configuration, e.g. when changing from xylene to isopropanol,
ParaLast and if the operating mode (Concentration/Auto by RMS) is switched.
• If the instrument is to be moved or transported for long distances.
• If the instrument is to be shut off for longer than one week (e.g. before vacation periods, etc.).
The prerequisite for the start of SMART cleaning is that the retort has been thor-
oughly cleaned using the extended cleaning mode and that there is no reagent
in the retort.
Only in this way is it possible to ensure that no residue from other reagents gets
into the newly defined stations.
Before transporting the instrument, in addition to the SMART cleaning, ensure
that no reagent residue is in the bottles.
Likewise, there must be no wax in the retort, the paraffin baths or the paraffin
station.
