Product description
The spiral motion feeds the separated fluid con-
tinuously to the pump wheel, which transports
the fluid into the collector vessel� The fluid is
transported to the centrifuge (8) via a pump
cone (11)�
An external station selection valve connects
the CAS1 with the suction unit via the vacuum
connection (2)�
5.3 Spittoon connections
The waste water from the spittoon flows through
a protective strainer on the fluid inlet (1) and
into the collector vessel (12)� Once sufficient
fluid has been collected, the float sensor (13)
activates a light barrier (9a) and (9b) via a sensor
housing (10) and switches on the motor (1)� The
fluid is transported to the centrifuge (8) via a
pump cone (11)�
5.4 Station selection valve / safety
valve
The station selection valve has 2 tasks:
1st task:
The station selection valve interrupts the suction
flow between the hose manifold and the suction
unit� As soon as a suction hose is removed
from the hose manifold, a solenoid valve opens
the station selection valve and suction flow is
enabled�
2nd task:
The station selection valve also acts as a safety
valve� If the CAS1 is over-full or not functioning
properly, the system will perform a safety shut-
down� This safety shutdown prevents fluids from
being drawn into the dry suction pipe�
For single station suction systems, the
station selection valve takes over the
function of the safety valve�
In various types, a station selection valve is
already integrated in the CAS1� The station
selection valve is on the connection (2) of the
CAS1�
5.5 Amalgam separation
The switches in the hose manifold or the light
barrier of the sensor system switch on the
motor and the associated centrifuge (8)�
The fluid containing amalgam particles flows
continuously to the collector vessel (12)� The
fluids ejected by the centrifuge are pumped
through the fluid output (4) to the central waste
water system�
5.1 Operation
CAS1 Combi-Separator
The task of the CAS1 combi-separator is to
provide continuous separation of secretions and
air as well as the amalgam separation of all the
waste water from the treatment unit�
The waste water flows through the connection
(1) from the spittoon directly into the centrifuge
(8) and amalgam separation�
During the suction phase the aspirated secre-
tions are separated from the aspirated air in the
separation unit (6)� The secretions accumulating
in the separation unit are continuously trans-
ported to the centrifuge (8), where the amalgam
particles are then separated�
Underneath the centrifuge is a replaceable
amalgam collector vessel (12), into which the
separated amalgam particles (15) are rinsed
once the centrifuge (8) is switched off� A float
sensor (13) checks the level within the collector
vessel and sends a signal to the display panel
when it needs replacing� In combination with a
light barrier (9c), this float sensor also monitors
whether a collector vessel is in use�
The compact size of the CAS1 Combi-Separa-
tor allows it to be installed in dental treatment
units� This results in short secretion carrying
lines� After the centrifuge is switched off, the
braking cycle triggers a self-cleaning process�
This self-cleaning process also leads to smooth
and silent running, as well as providing a sepa-
ration efficiency of more than 95%, even under
heaviest loads�
5.2 Separation
At the inlet connection (3) of the CAS1, the
aspirated fluid/air mix is accelerated and set into
a spiral motion in the separation unit (6)� The
resulting centrifugal forces sling the aspirated
particles against the outer wall� The air is contin-
uously separated from the fluid and escapes via
the spinning separation rotor (7) to the suction
unit�
The aspirated air is subject to high centrifugal
forces by the separation rotor (7), which is
driven by the motor (1), which ensures that no
fluid or blood foam can be carried into the suc-
tion unit�
EN

7117100018L30 1712V002 11
Product description
As soon as no further fluid is fed to the amal-
gam separator, e�g� when the suction hose is
placed back in the hose manifold, the centrifuge
drum is switched off after a short delay time�
This switch-off brakes the motor, as a result
of which the ring of water, which continues to
rotate due to inertia, rinses the separated parti-
cles out of the centrifuge (8) downwards into the
collector vessel�
The separated amalgam particles form a sed-
iment in the replaceable collector vessel� The
level of fluid in the collector is regulated by the
pump cone so that the risk of fluid escaping
when the collector vessel is changed can be
avoided�
5.6 Sediment level measurement
The fill level in the collector vessel (12) is
checked by a float sensor (13) every time the
main power switch is switched on�
The centrifuge motor starts, fluid is transported
via the pump cone to the centrifuge drum (8)
and provides a constant level of fluid (under-
side of the cone pump) in the collector vessel�
The float sensor sinks� Two light barriers (9a)
and (9b) measure the fluid level� Once the level
reaches 95% in the collector vessel, this is dis-
played on the display panel�
5.7 Operating problems
If the unit is not ready for operation due to a
fault, this will be indicated on the display panel
via illuminated LEDs and an audible signal�
5.8 Service key
On the display panel there is a service key that
can be used to switch off the audible signal in
the event of a fill level warning or if a fault mes-
sage is indicated� This button can also be used
to start the device manually� To do this, press
the button for longer than 2 seconds until the
drive motor starts up�

7 Installation
Prior to working on the device or in case
of danger, disconnect it from the mains
(e�g� pull the mains plug)�
7.1 Combining devices safely
Take care when connecting units together or to
parts of other systems as there is always an ele-
ment of risk (e�g� due to leakage currents)�
iOnly connect units when there can be no
question of danger to operator or to patient�
iOnly connect units when it is safe to do so
and there is no risk of damage or harm to the
surroundings�
iIf it is not 100% clear from the unit data sheet
that such connections can be safely made or
if you are in any doubt, always get a suitably
qualified person (e�g� the manufacturer) to
verify that the setup is safe�

Spittoon connections
In some dental units it is possible that noises
can be heard at the spittoon, which are ampli-
fied by the funnel shape of the spittoon itself�
In this case, the outlet between spittoon and
CAS1 should be bled� A corresponding siphon
trap with ventilation is available as a special
accessory�
Rinsing unit
It is recommended that the suction system is
equipped with a rinsing unit, e�g� in the treat-
ment unit� The rinsing unit provides a small
amount of water during aspiration� This dilutes
the aspirated fluids (blood, saliva, rinsing water,
etc�), which can then be transported more effec-
tively�
For further information, refer to the rinsing unit
installation and operating instructions
7.2 Installation of the CAS 1 in
treatment units
WARNING
Infection due to contaminated unit
iClean and disinfect the suction before
working on the unit�
iWear protective equipment when
working (e�g� impermeable gloves,
protective goggles and mouth and
nose protection)�
Attach the unit vertically at a suitable position
in the treatment unit�The unit is mounted on
rubber pads and suspended in a metal frame�
This mounting arrangement prevents the trans-
mission of any vibrations to the treatment unit
while the device is running� Vibrations may
occur if the unit is not positioned vertically� A
minimum distance of 3mm must be maintained
to the surroundings�
Station selection valve
In various types, the station selection valve is
directly mounted on the CAS1� The station
selection valve (for separate installation) should
be fitted in the suction pipe in the treatment
unit, preferably near the end connection in the
floor socket� In some installation setups the
station selection valve also functions as a safety
valve, so its actuation must be implemented via
the CAS1�
For further information, refer to the station selec-
tion valve installation and operating instructions

At the connection for the rinsing unit, a
suction unit relay, forexample, can be
connected if there is no isolation pres-
ent between the suction unit signal and
station selection valve in the treatment
unit� Note the power consumption of the
suction unit relay�
Display panel
The display panel is used to indicate
messages acoustically and visually (via
LEDs)�
A display panel is already integrated in the unit
and should be visible/audible at all times�
If the display panel is not visible/audible, fit an
additional display panel in an easily visible loca-
tion� The display panel is connected to the X6
socket (RJ-45 socket)� An existing Dürr Dental
display panel with a 6-pin connector can be
connected to the X6A connector when replacing
an older device�
If the installation of the amalgam separator in a
neighbouring room or in the basement results
in distances of more than 3m, we recommend
installing a shielded network cable with RJ-45
sockets�
