6.2
Changing the suction motor
The motor of the suction device has a service life of approx. 1,200 hrs.
You will notice the motor is worn when suction does not start in either
automatic or manual mode. When this happens, have the motor
replaced by a trained service engineer.
6.3
Using the cleaning hose and the wet cleaning
process
CAUTION
Risk of injury on calibration pins/instruments
If you put your hand in the production chamber, you could injure it on
the calibration pins / instruments.
Be careful not to brush against the calibration pins/instruments with
your hand.
The processing chambers of devices used for dry milling of zirconium
oxide should be cleaned regularly in order to prevent deposits of
zirconium oxide dust in the chamber. A manual suction set with cleaning
hose can be used before the wet cleaning process in order to support
the user when vacuuming zirconium oxide dust out of the device's
processing chamber. This set is available as a spare part (REF 67 21
307). We recommend vacuuming the chamber after each dry-milled
restoration and performing a wet cleaning process (or wet grinding of a
restoration) at least once a week.
Proceed as follows to use the manual suction set and to execute the
recommended wet cleaning process:
1. CEREC MC XL / MC X / MC: Open the door of the production
chamber. The motors are in the home position.
