Operation
The toilet is flushed by pressing the push button. The pneumatic push button is connected to control mechanism with
a control hose, which transports the air pulse from push button to control mechanism. The air pulse starts the flushing
cycle and connects the vacuum to water valve and discharge valve.
The water valve opens and lets rinsing water into the bowl through a flushing ring. After a short delay, the vacuum acts
in discharge valve housing and forces the rubber diaphragm in discharge valve to open, thus connecting the bowl to
vacuum sewer. The contents of bowl are forced into the vacuum sewer by a pressure difference between the bowl and
vacuum sewer.
The flushing cycle in the control mechanism starts the closing cycle. Athmospheric air pulse enters the discharge
valve, which closes. After a short delay, athmospheric air pulse reaches water valve, which closes and lets a certain
level of water at the bottom in the bowl.
After the flushing cycle has stopped, the push button and system will be ready for next flush.
