Waste Circuit Interlock Device
To prevent the interconnection of the chamber with the waste water circuitry, the interlock is composed of two systems:
• One system inside the chamber which prevents utilization of the toilet until the exhaust valve is closed.
• One system outside the chamber which allows expulsion of the content of the waste water tank only when the connection to the chamber is closed.
The system shall aslo features skin valves that are not represented on the drawings.
