5.1 Operating function
The waste water from the spittoon flows through
the coarse filter into the collector vessel If
enough fluid is present then the magnet in the
float sensor is detected by the control electron-
ics The control electronics start up the suction
unit with the suction unit relay and actuate the
solenoid valve for the compressed air supply
The inflowing compressed air opens the shut-off
valve via a piston The fluid from the collector
vessel is then sucked into the suction pipe As
soon as the fill level in the collector vessel has
dropped, this is detected by the control elec-
tronics and the solenoid valve is switched off
While waste water continues to flow in from the
spittoon the collector vessel refills and the proc-
ess starts again from the beginning
5.2 Cleaning function
The cleaning function is activated by permanent
pressure on the yellow cleaning button on the
spittoon valve or on the cleaning button on the
switch control panel (if present) As a result the
solenoid valve for the compressed air supply,
and therefore the shut-off valve, is opened and
the suction unit relay is actuated in order to start
up the suction unit
The cleaning and disinfection solutions can now
be aspirated without hindrance through the spit-
toon valve into the suction pipe and into the
suction unit A suction noise can be heard at the
spittoon
