How to Create Custom Vacuum Zones
Clean with isopropyl alcohol the area of the overlay sheet where the new foam tape
3.
is to be applied.
Measure and add foam tape in desired locations to create zones. When creating a
4.
zone it is recommended active vacuum holes are a minimum of 15 mm from the
outside edges of the media. This will optimize the sealing effect between the media
and the table.
Flip the overlay sheet over and position it on the registration pins.
5.
Completely cover all zones, close the bleed valve, turn on vacuum and verify the
6.
closed system vacuum level is > 20 inches of Hg. Also verify that the time it takes
for the vacuum to establish is less than 4 seconds.
Repeat step 6 for the all other zones individually.
