6 Maintenance and repair
CAUTION
Risk of uncontrolled release of fine dust
If the suction device is not operated with the inserted filter bag or
HEPA filter provided, fine dust may be discharged uncontrollably.
➢ Only operate the suction system with original spare parts (see
“Spare parts and consumables [→ 26]“).
6.1 Changing filter bags and HEPA filters
Changing filter bags
If there is a significant fall in suction power, the filter bag could be full
and will need replacing.
NOTE
For the CEREC suction device, we recommend changing the filter
bag at the following intervals:
CEREC MC XL / MC X / MC: after approx. 120 restoration units.
After 120 dry-milled restorations, a notice appears on the home
screen of the touch interface. This number may differ depending on
the amount of zirconium oxide material milled and suctioned.
CEREC Primemill: after around 8 hours of processing.
After 8 hours of processing, a yellow warning appears on the home
screen of the touch interface. If the filter bag is not changed, a red
error message appears after 10 hours of processing.
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.
4. Put the maintenance cover on and screw it down with the two
knurled nuts.
NOTE
Do not jam the filter bag
Make sure that the cap is sealed properly and the filter bag is not
jammed.
