7. Cleaning and Maintenance
Editing steps
• To edit a program step, highlight the corresponding line and press the respective table header.
• To disable a step, set the number of cycles to "0". Only cleaning water steps can be disabled.
The following characteristics of each step can be edited:
• Reagent name - only those reagents that are compatible with the reagent station being edited
will be displayed.
• Number of cycles - the duration displayed is calculated based on the number of cycles.
• Retort temperature - temperatures from 50 to 65 °C can be set.
The finish times of clean programs cannot be edited. Program duration is calculated auto-
matically based on the number of cycles set.
Station 13-ext
• The designation "13-ext" is used for an additional station that can be used in place of the
standard station 13.
• Station no. 13 always contains cleaning water. For some applications it is desirable to use a
cleaning water/agent mixture between the cleaning alcohol and the cleaning water.
• If a program contains the step "Station 13-ext", the operator is prompted to insert the reagent
container "13-ext" at the required point in time during the cleaning program, then to remove
it once it is no longer used.
The station 13-ext can be assigned exclusively to reagents from the cleaning water
group. It may only be used for cleaning programs.
7.1.1 Retort cleaning programs (continued)
• The steps of retort cleaning programs are listed in the order in which they are carried out
( Fig. 81) .
• The cleaning program skips any steps not required to complete the cleaning. If, e.g. an infiltra-
tion 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.
