The mixture of liquids, solid particles and air drawn in passes through the inlet connection and into
the suction unit� The coarse filter holds back the solid particles�
Inside the separation unit, the aspirated fluids and solid particles pass through a two-stage separation
system and are separated from the suction air� This separation system consists of a cyclone separa-
tor and a separation turbine�
The aspirated mixture flows into the cyclonic separator, where it is set into a spiral motion� In this first
stage, the resulting centrifugal forces force the fluid constituents and any remaining solid particles
against the outside wall of the separation chamber of the cyclone separator� This initially only effects a
"coarse separation" of the fluid�
In the subsequent second stage, the separation turbine effects "fine separation" of the remaining liq-
uid from the air flow that has carried it to this point�
EN

9000-606-31/30 1905V003 13
Product description
The fluid and solids accreting in the separation chamber are continuously fed to the amalgam centri-
fuge, where the amalgam particles are removed� The fluid extracted via the centrifuge is fed through
the waste water valve and the outlet connection into the central waste-water system�
Under the centrifuge there is an interchangeable collecting container into which the separated amal-
gam particles fall once the motor is switched off�
A sensor checks the fill level in the collecting container, and when it is full, an LED on the display pan-
el indicate that the collecting container needs to be replaced� Depending on the type of work carried
out and the amount of amalgam arising, the collector vessel should be changed approx� every
6-9months� A secure twist cap makes the replacement and closing of the collector vessel easier�
A pump connected to the centrifuge keeps the fluid level constant in the collecting container� This
prevents accidental overflow when replacing the collecting container�
The air separated from the liquid is sucked off by the vacuum pressure generated by the turbine
wheel� The air is then blown through the noise reduction hood and over the exhaust air connection
and out of the machine�
The turbine wheel, separation turbine and amalgam centrifuge are driven by the motor�

6.3 Use of nitrous oxide
This unit is technically suitable for the aspiration
of nitrous oxide (laughing gas)� However, when
assembling a system for aspiration of nitrous
oxide, it is important to ensure that the other
components in the system are also suitable for
this purpose� Those responsible for setting up
the system must assess this and approve and
release the system for the aspiration of nitrous
oxide�
Operation with nitrous oxide is only per-
mitted if the exhaust air is transported
from the unit to the outside of the build-
ing�
6.4 Pipe materials
Only use vacuum-sealed HT-waste pipes
manufactured from the following materials:
– Polypropylene (PP),
– Chlorinated polyvinyl chloride (PVC-C),
– Unplasticized polyvinyl chloride (PVC-U),
– Polyethylene (PE)�
The following materials must not be used:
– Acrylonitrile-butadiene-styrene (ABS),
– Styrene copolymer blends (e�g� SAN + PVC)�
6.5 Hose materials
For waste connections and suction lines only
use the following hose types:
– Flexible spiral hoses made of PVC with inte-
grated spiral or equivalent hoses
– Hoses that are resistant to dental disinfectants
and chemicals
Plastic hoses will display signs of ageing
over time� Therefore, they should be in-
spected regularly and replaced as neces-
sary�
The following types of hoses must not be
used:
– Rubber hoses
– Hoses made completely of PVC
– Hoses that are not sufficiently flexible

6.6 Installation and routeing of hos-
es and pipes
iExecute the on-site pipe installation in accord-
ance with the applicable local regulations and
standards�
iLay the hose installation of the drains to or
from the unit at a sufficient incline�
If incorrectly laid, the hoses can be-
come blocked with sedimentation�
6.7 Information about electrical
connections
iEnsure that electrical connections to the
mains power supply are carried out in accord-
ance with current valid national and local reg-
ulations and standards governing the installa-
tion of low voltage units in medical facilities�
iInstall an all-pole disconnect switch with a
contact opening width of at least 3mm in the
electrical connection to the mains power sup-
ply�
iObserve the current consumption of the de-
vices that are to be connected�

7.5 Noise reduction
If the noise level from the exhaust air vent or the
flow noise generated is too high, noise reduction
can be installed in the exhaust air line�
7 System components
The system components listed below are re-
quired or recommended for various procedures
or for installation�
7.1 Rinsing unit
In the absence of a spittoon or rinsing unit in the
treatment unit, it is absolutely essential that a
rinsing unit be installed in the VSA300S� In ad-
dition, for surgical procedures and for proce-
dures using airflow a rinsing unit must always be
installed in the treatment unit to supply a small
amount of water to the system during aspira-
tion� Any secretions present will thus be diluted
and can be transported away more easily�
For further information, refer to the rinsing unit
installation and operating instructions
7.2 Spittoon valve
To ensure that the waste water from the spit-
toon bowl is directed into the suction pipe, a
spittoon valve needs to be installed between the
drain of the spittoon bowl and the suction pipe�
The spittoon valve must switch on the suction
machine if required�
7.3 Flow accelerator
In order to keep the suction system free of de-
posits, a flow accelerator can be fitted in con-
junction with a spittoon valve� When using a
bowl rinse system, water will collect before the
flow accelerator� The next time suction takes
place using the large cannula, the collected fluid
is transported in surges and at high speed to
the suction system� This ensures automatic
cleaning of the suction pipes�
7.4 Exhaust air filter
For hygienic reasons, we recommend the instal-
lation of a bacteria filter in the exhaust air line�
If the unit is installed in the surgery and the ex-
haust air cannot be discharged to the outdoors,
it is essential to install a bacteria filter�
Depending on the type and condition of the
bacteria filter, it will need to be replaced every
1-2 years at the latest�
The separation integrated in the system
does not retain bacteria; this is why we
recommend installing a suitable filter in
the exhaust air system�

The actual connection can vary depending on the chosen installation option� The connection
shown is only an example�
8.1 Installation and routeing of hoses and pipes
iEstablish connections between the pipe system and the unit using the flexible hoses supplied� This
will prevent vibrations from being transmitted to the pipe system�
iThe connection between the pipe line and unit suction connection should be kept as short as pos-
sible and straight, without bends�
iInstall the drain hoses with a downward gradient so that the waste water can drain off�
iWaste water connections must be implemented in accordance with applicable local and national
regulations�
