1Safety
1.1 Proper use
The CERCON CLEAN single-user vacuum-cleaning unit is used in dental
laboratories for the removal of the dust generated when working with dust-
producing machinery. It is not permitted to attempt to use this unit for the
removal of liquids.
This vacuum-cleaning unit is suitable for removing Category C dust as per
the requirements of the German employers mutual insurance associations
pursuant to DIN EN 60 335-269 (ZH 1/487).
Unauthorized changes and modifications are prohibited for safety reasons.
Compliance with the operation and service conditions laid down in these
Instructions for Use is mandatory.
Caution This unit was not designed as a medical device. Its use on humans is not
permitted!
1.2 Potential hazards
-Do not vacuum any sources of ignition and no flammable gases, fumes and
liquids.
-Turn off the unit using the mains switch before any maintenance,
cleaning or repair work, and physically disconnect from mains (by
unplugging the mains cable).
-Because the vacuumed dust can constitute a health hazard, care
must be taken and insure that the filter bag and the ultra-fine filter are
inserted correctly at all times and that they are undamaged.
-Before accessing the electrical component of the unit, the unit must be
disconnected from mains.
1.3 Authorized operators
The person or entity responsible for the operation of the unit must provide
the operator with the Instructions for Use and ensure that the latter has read
and understood them. Not until this is ensured will the operator be permitted
to operate the unit.
1.4 Safety precautions at the deployment site
The air from the air outlet (45) must be allowed to exit unimpeded.
The distance from the air outlet to the next obstacle (e.g. wall, piece of
furniture) must be at least 10 cm.
The unit must only be used inside cabinets or small rooms if proper
ventilation is ensured. The ambient temperature must not exceed 25 °C.
Do not insert any foreign matter into the unit through the vent openings.

4/15
Danger The unit is not suitable for use in rooms in which special conditions prevail
(e.g. a corrosive or explosive atmosphere).
1.5 Conventions used for the safety instructions in these
Instructions for Use
Note Indicates a practical hint to the user or other particularly useful information.
Caution Indicates a usage or mode of operation whose non-observance may result in

2 Commissioning
2.1 Unpacking the single-user vacuum-cleaning unit
1. Place the box on a level surface.
2. Remove the outer packaging material.
3. Push the packaging material always from the unit and seize the lower edge
of the unit.
4. Two people must be present to lift the unit out of the box (weight
approximately 25 kg).
5. Check to ensure that all components are present:
-Documentation
-Mains cable
-Control cable
-Vacuum hose, 40 mm in diameter, 2 m in length, with two 40-mm
connecting ducts
-Single-use filter bags, paper, 5 ea.
2.2 Short description of the unit –Identification of components
The CERCON CLEAN single-user vacuum-cleaning unit features a powerful
noise-reduced high-capacity pressure fan and is equipped with an internal
potentiometer for regulating the amount of air, an automated power-off
function and a filter change indicator.
The vacuum-cleaning unit can be operated on any voltage between 200 and
240 V without any effect on the preset input air volume.
The CERCON CLEAN is used as a vacuum accessory for dental milling
units.
The vacuum function is turned on automatically as soon as the milling unit is
activated.
The dust is collected in a double-layer single-use filter bag made of paper.
The capacity of this filter bag can range up to 10 kg depending on the type of

5/15
dust collected. The large-area ultra-fine filter downstream from the single-
use filter bag is capable of holding back Category C dust1.

3 Operation
3.1 Checking the filtration module
(see Figs. 1 and 2 on page 4)
Caution The CERCON CLEAN single-user vacuum-cleaning unit must not be
operated without an ultra-fine filter (31) and a filter bag (11), both correctly
installed and undamaged.
1. Open the two clamp locks (3) and remove the cover (2).
2. Check to ensure that the ultra-fine filter (31) is undamaged and tightly
pressed against sealing surfaces (24) using the ledge (29).
3. Check to ensure that the two M6 nuts (28) are tightened firmly and
equally.
4. Check to ensure that the mounting cover (5) is tightly screwed into
place using the two thumb screws (6).
5. Check to ensure that the filter bag (11) is inserted properly in the
basket (12) and that it is undamaged.
6. Check to ensure that the plastic connector (10) of the filter bags is
seated tightly on the connecting duct (15).
7. Replace the cover (2) and close the two clamp locks (3).
3.2 Air volume control
Note The fuller the filter bag (11), the less powerful the vacuum.

8/15
Thanks to the built-on power stabilizer, the preset input air volume is kept
constant as the mains voltage changes (between 180 and 264 V).
3.3 Automatic turn-off and filter change indicator
(see Fig. 6 on page 9).
Note As soon as the filter bags (11) has been filled to the maximum permissible,
an underpressure switch will actuate the automatic turn-off function, and the
filter change indicator on the milling unit will be lit. The vacuum will not be
turned off until the milling procedure is completed. The milling unit can only
be turned back on when the filter bag has been replaced or the ultra-fine
filter cleaned.
1. The filter bag (11) has to be replaced, see Section 4.1.
Note If the automatic turn-off function has turned off the unit, cycling the unit off
and on and tapping the filter bag (11) will allow the operator to keep working
for a little while longer without having to replace the filter bags.
2. To tap the filter bag (11), open the two clamp locks (3) and remove the cover
(2) (see Figs. 1 and 2 on page 4).
Note If the automatic turn-off function has turned off the unit (filter change
indicator is lit) and the filter bag (11) turns out not to be full, the ultra-fine
filter (31) must be checked (see Section 4.3).
4 Cleaning and maintenance
4.1 Replacing the filter bag
(see Figs. 1 and 2 on page 4 and Fig. 4 on page 7)
1. Open the two clamp locks (3) and remove the cover (2).
2. Use both hands to pull the plastic connector (10) off the duct (15).
3. Close the filter bag (11) using the attached plastic cover (17).
4. Carry the filter bag (11) to the designated disposal site within its basket (12)
and dispose of properly.

9/15
Fig. 4: Removing the filter bag
Caution The single-use filter bags must never be emptied and reused. Not only might
this constitute a health hazard, but it would also impair the function of the
unit.
Caution Do not use pressurized air to remove any dust present in the filtration
chamber (20).
Do not allow any foreign matter to enter the air intake opening (26) because
this might damage the vacuum motor.
5. Insert the new filter bag snugly and check the filtration module (see Section
4.2).
4.2 Inserting the filter bag
(see Fig. 1 on page 4 and Figs. 6 and 7 on page 9)
1. Fold new filter bag (11) as shown in Fig. 5 and insert into basket as shown
(12).

10/15
Fig. 5. Inserting the filter bag
2. Slide the new filter bag (11) in its basket (12) into the unit. The duct of the
filter bag (10) will engage the duct (15) inside the filtration chamber (20)
tightly.
3. Slide the plastic connector (10) tightly onto the housing duct (15) of the
vacuum unit.
4. Place the cover (2) on the housing (1) and tighten using the clamp locks (3).
4.3 Cleaning (replacing) the ultra-fine filter
(see Figs. 1 and 2 on page 4 and Fig. 6 on page 9)
Note Approximately every tenth time the filter bag (11) is changed, the ultra-fine
filter (31) should be removed and cleaned (dry cleaning process) or
replaced.
We will be happy to clean the ultra-fine filters (31) for you by way of a filter
exchange. In this way you can be certain that only type-tested filters
pursuant to DIN EN 60 335-2-69 (ZH 1/487 para. 2 with a certificate
pursuant to DIN 24184) are used.
1. Open the two clamp locks (3) and remove the cover (2).
2. Open and remove the thumb screws (6) and und mounting cover (5).

11/15
3. Loosen the two nuts (28) and lift out the ledge (29) with the longitudinal
holes.
4. Remove the ultra-fine filter (31).
Caution No dust may be present on the sealing surfaces (24) or in the air intake
chamber (32), as the dust may damage the vacuum motor (23).
The air intake chamber (32) and sealing surfaces (24) must be cleaned by
vacuuming. Do not use pressurized air.
5. Insert the cleaned or new ultra-fine filter (31).
6. Slide the ledge (29) onto the threaded pins from above.
7. Tighten the two M6 nuts (28) firmly and equally.
8. Tightly screw the mounting cover (5) into place using the two thumb screws
(6).
