Changing filter bags
The touch display automatically displays a notification to change the
filter bag of the CEREC suction system after 120 dry-milled restoration
units. This number may differ depending on the amount of zirconium
oxide materials milled and suctioned. If the filter bag is full before the
notification, the touch display might display a warning at low pressure,
meaning that the filter bag needs to be replaced.
NOTE
If there is a significant fall in suction power, the filter bag could be full
and will need replacing.
1. Loosen the two knurled nuts (A) on the maintenance cover.
2. Remove the lid.
3. Remove the filter bag from the nozzle and put a new filter bag on.

NOTE
Do not jam the filter bag

jammed.
