7. Cleaning and maintenance
7.1 Clean programs
The cleaning programs are at the end of the list of all pro-
grams ( Fig. 43 ). To display a clean program, highlight the
respective line and press EDIT.
A cleaning program comprises a
minimum of three and a maximum
of four steps:
1. Solvent
1 step from station 11
2. Cleaning alcohol
1 step from station 12
3. Cleaning water
1 step from station 13
Optional between steps 2 and 3:
Cleaning water/detergent
1 step from station 13-ext.
• The steps of retort clean programs are listed in the order in which they are carried out ( fig. 73 ).
• The clean programs skip any steps not required to complete the clean. If, e.g. an infiltration
program has been aborted during the alcohol step, the subsequent clean program will skip the
cleaning solvent step and will start with the cleaning alcohol step.

Three retort cleaning programs and a paraffin cleaning program are defined in the ASP300 S.
Clean programs cannot be copied or deleted.
Replacement schedule for cleaning reagents:
The cleaning reagents (cleaning xylene and cleaning alcohol) must be replaced weekly ( refer
to Chapter 3.6.1 ).
If fatty tissue, bloody tissue, biopsy sponges or the like are processed, both the reagents and
the cleaning reagents must be replaced more frequently.
