5.1 Operation
CAS 1 Combi-Separator
The task of the CAS 1 combi-separator is to pro-
vide 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 transpor-
ted to the centrifuge (8), where the amalgam par-
ticles are then separated.
Underneath the centrifuge is a replaceable amal-
gam collector vessel (12), into which the separa-
ted 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 collec-
tor vessel is in use.
The compact size of the CAS 1 Combi-Separator
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-clean-
ing process also leads to smooth and silent run-
ning, as well as providing a separation efficiency
of more than 95%, even under heaviest loads.
5.2 Separation
At the inlet connection (3) of the CAS 1, the aspi-
rated fluid/air mix is accelerated and set into a
spiral motion in the separation unit (6). The result-
ing centrifugal forces sling the aspirated particles
against the outer wall. The air is continuously
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 suction unit.
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 con-
nection (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 ena-
bled.
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 con-
tinuously to the collector vessel (12). The fluids
ejected by the centrifuge are pumped through
the fluid output (4) to the central waste water
system.
As soon as no further fluid is fed to the amalgam
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-

EN

off brakes the motor, as a result of which the ring
of water, which continues to rotate due to inertia,
rinses the separated particles out of the centri-
fuge (8) downwards into the collector vessel.
The separated amalgam particles form a sedi-
ment 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 (underside of the
cone pump) in the collector vessel. The float sen-
sor sinks. Two light barriers (9a) and (9b) meas-
ure the fluid level. Once the level reaches 95% in
the collector vessel, this is displayed on the dis-
play 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 illu-
minated 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 message 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.

danger, disconnect it from the mains.
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).
❯Only connect units when there can be no
question of danger to operator or to patient.
❯Only connect units when it is safe to do so and
when there is no risk of damage or harm to the
surroundings.
❯If 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 ver-
ify that the setup is safe.
7.2 Installation of the CAS 1 in
treatment units
The CAS 1 Combi Separator for KaVo treatment
units must be set up in a defined installation
setup in order to meet the relevant safety stand-
ards. For this reason it must only be installed in
the treatment units that have been designed and
approved for this purpose by KaVo.
KaVo-approved treatment units:
New units delivered from 01/2016 onwards: E50,
E50 Life, E70/E80, E70/E80 Vision, 1058, 1058
Life
Spare parts requirements for old units such as
1078 and 1080 among others.
WARNING
Infection due to contaminated unit
❯Clean and disinfect the suction before
working on the unit.
❯Wear 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 transmission
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 surround-
ings.
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
Inlet and outlet hoses
Connect and attach the inlet and outlet hoses
with DürrConnect connectors to the relevant
connections on the unit. Route the hoses at an
incline.
Recommended diameter of the connection
hoses: Æ25 mm.
The minimum nominal width for the outlet hose is
15 mm.

Spittoon connections
In some dental units it is possible that noises can
be heard at the spittoon, which are amplified 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 treatment
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 effectively.
