OPERATING INSTRUCTIONS
4.12 Revised 10/02/2012
Special Conditions and
Considerations
Understanding the Process
Scheduler
In order to achieve continuous processing, the instru-
ment’s scheduling software internally calculates a process
schedule to efficiently process and transfer the specimen
basket or magazine set. Depending upon the immersion
times and number of baskets or magazine sets simultane-
ously in process, the instrument’s internal process
scheduler may create a delay to prevent baskets or
magazine sets from immersing too long in Retorts #1 or
#2 if baskets or magazine sets in the Unloading Station
are not removed.
For example, if four baskets or magazine sets are
processed simultaneously, and the duration of the
immersion time is 15 minutes for each of the four pro-
cessing stations, the start of processing for the next
basket or magazine set in the Loading Station may be
delayed even though Retort #1 is READY. This is not an
error. The basket or magazine set in the Loading Station
will be transferred within 20 minutes.
Reagent Volume Monitor
Each time a basket or magazine set is transferred, the
instrument checks the reagent volume when the reagent is
pumped into retort. If the instrument detects that the
reagent level is not sufficient for the next basket or set, the
word, “SHORTAGE” displays in the STATUS row on the
Process Monitor screen. The instrument will continue
processing the basket(s) or magazine set(s) that are
already in process, however, the instrument will not accept
any new baskets or magazine sets until the shortage is
corrected.
If a “SHORTAGE” occurs, proceed as follows:
1. Allow all baskets or magazine sets currently being
processed to complete their processing.
2. Remove the baskets or magazine sets from the
Unloading Station when processing is completed.
3. Perform a manual shutdown of the instrument (see
“Manual Shutdown” on page 4.11 for details).
4. After the shutdown process has completed, replace
all reagents (see “Pre-Processing Solution Replace-
ment” on page 7.3 for details).
On board Pre-Processing Solution must be replaced
on condition (after a specified number of hours) to ensure
proper preprocessing. The instrument can be configured
to count the number of hours the solution has been in the
instrument to aid in determining when to replace the Pre-
Processing Solution (see “System Operation”, page 4.5).
NOTE: Depending on the types of tissues processed the
Pre-Processing Solution should be replaced every 3
hours.
To replace the Pre-Processing Solution:
WARNING: THE PREPROCESSING CONTAINER MAY
CONTAIN BIOHAZARDOUS WASTE. DISPOSE OF
THE CONTENTS IN ACCORDANCE WITH LOCAL
REGULATIONS.
1. Open the Loading Station Door.
2. Remove the loading Station Container.
3. Discard the Pre-Processing Soution per local
regulations.
4. Wipe the inside of the loading station container with
gauze.
5. Perform a manual start of the instrument (see
“Manual Start” on page 4.3 for details).
6. When the WARMING UP SYSTEM cycle is complet-
ed (see “System Warm Up (Figure 4-E)” on page 4.4
for details), the user may resume processing.
Door Open
To prevent the risk of injury due to contact with the
Transfer Arm while in motion, the Transfer Arm stops
moving immediately when any Access Door (Loading
Station Access Door, Retort Access Door or Unloading
Station Access Door) is opened during processing. The
instrument resumes processing when the door is closed.
