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
i
Clean and disinfect the suction before
working on the unit�
i
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 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
