Chapter 3
1) Type of Cleaning Operations
There are two types of cleaning operations: Retort cleaning where the interior of the retort and tubing are cleaned
with cleaning xylene and cleaning alcohol to clear attached paraffin, and warm water flush where precipitate
build-up formed in the interior of tubing when neutral buffered formalin is used are cleaned with warm water.
2) Starting Retort Cleaning
Retort cleaning is performed in one of two ways: Perform retort cleaning at when the tissue processing ends (or
is aborted), or select Clean Retort on the Utility screen.
The cleaning details are the same.
 Retort cleaning when the tissue processing ends
(or is aborted)
Once the tissue processing ends, the specimens are
removed and the retort is drained, the retort cleaning
start screen appears. After confirming the message,
touch Confirm.
Touching START starts retort cleaning. The retort is
warmed up to 70°C for 10 minutes. Thereafter, clean
retort nine times with Sta. C1 (cleaning xylene), and
clean five times with Sta. C2 (cleaning alcohol). At the
end, the retort is dried. When finished, the completion
window appears.
Note
The same applies when Clean Retort is
selected on the Utility screen.
Caution!
If retort cleaning is not performed within 10
minutes after switching to this screen, a
window with the waning message "Start Clean
Retort" appears.
Touching EXIT takes you back to the standby
screen, but if paraffin has been filled in the
retort, tissue processing, warm water flush
and automatic transfer cannot be performed
unless the retort is cleaned.
 Retort cleaning from the Utility screen
Touch the Utility tab to display the Utility screen.
Touch the Clean Retort icon.
Touching START starts retort cleaning.
Note
Details are the same as with the retort cleaning
performed when the tissue processing ends
(or is aborted).
Caution!
Confirm that no specimens are left in the
retort. Remove the paraffin deposits on the
back of the retort lid. If retort cleaning is not
performed within 10 minutes after switching to
this screen, a window with the waning
message "Start Clean Retort" appears.
Touching EXIT takes you back to the standby
screen, but if paraffin has been filled in the
retort, tissue processing, warm water flush
and automatic transfer cannot be performed
unless the retort is cleaned.
When the retort cleaning is complete, clean
the retort lid, interior walls of the retort and
areas around the retort.
