A vacuum drain removes waste from the toilet bowl to an underfloor waste holding tank. An electronic vacuum system controller controls the system and related electronic components. The toilet system is divided into:
-
The cabin installation
-
The cabin underfloor installation.
The cabin installation has a single toilet assembly in each lavatory. The
cabin underfloor installation has:
-
A waste holding tank assembly
-
A Liquid Level Transmitter (LLT) (tank mounted)
-
A Liquid Level Sensor (LLS) (tank mounted)
-
A vacuum generator
-
A Vacuum System Controller (VSC)
-
A check valve (vacuum pressure)
-An altitude pressure switch
-
A check valve (installed in each flush Line of the waste tank)
-
A waste drain valve
-
A waste service panel
-The pipelines (overfloor and underfloor).
