2. Remove the Purge Ledge assembly by lifting it straight up.
3. Use a cleaning brush (in the system start-up kit) to remove debris from around the Tip Wipe and
Purge Ledge area.
4. Clean and inspect the surface around the locating pins - make sure that the Tip Wipe Assemblies
and Purge Ledge can sit flush on the surface.
5. Inspect the Kapton tape around the upper funnel chute. Replace the Kapton tape if wear or tears
are evident.
• The Kapton tape is secured to the upper funnel chute with self-adhesive material. To replace the
tape, peel the tape from the chute.
• Clean the area around the top of the upper funnel chute with Isopropyl alcohol and a clean, lint-
free cloth.
Peel the backing material from the new Kapton tape and carefully position the shield in place on
•
the upper funnel chute - the top edge of the adhesive area should be even with the top of the
chute.
• Press the Kapton tape in place to secure.
6. Inspect the Purge Ledge assembly:
• The purge surface should be free from pock marks or surface irregularities.
• Install a new purge ledge assembly if necessary. Use a PPSF purge ledge assembly when using
PPSF or ULTEM material.
