Grade 3: Full deep clean
If your new material cannot tolerate any contamination at all, you should clean the processing station
manually
.
Contact your service representative if you are not trained to do this yourself.
Purge the processing station
The processing station should be cleaned and purged before changing to a different type of material.
NOTE: You will need 30 liters of the new material (15 liters from each of the supplier connectors), to be
used f
or purging. This material will be disposed at the end of the purge process.
The purge process will use new material to recirculate it multiple times through all the subsystems and
ho
ses of the processing station. The new material circulation will remove the remaining particles of the
old material, and, eventualy, the purge process will get rid of it.
IMPORTANT: The processing station should always be cleaned before purging. See Clean the
processing station on page 283.
IMPORTANT: If the system is switched off in the middle of the process, the process will need to be
s
tarted again (cleaning included), and more fresh material will be needed.
CAUTION: It is important to keep the purge tool in the indicated position during the whole process. In
case o
f system error, do not disconnect the hoses; restart the processing station and restart the
process, or start an unpacking process to ensure that the material left in the hoses is properly cleaned.
If it is not possible to do either of these things, remove the tool from its position, keeping it horizontal to
avoid possible material spillages.
1. At the front panel, tap the Settings icon , then Material management > Purge processing
station.
2. Replace the external tank by a new one, which will be used for waste material.
3. Put in place the new material cartridges containing the material that you want to use.
