- Grey water tank
- Fresh water tank (optional)
- Communication via Thetford app or vehicle board control
- Discharge device
- Discharge storage bin

System flow
Depending on the settings, the toilet is flushed with fresh or grey water.
Toilet waste water goes to the black water tank. Additive from the
corresponding three cartridges are added in the process. When the black or
grey water tank is full, a notification will be visible in the communication
app. The tanks can be emptied at a designated place with the aid of the
discharge device.

button again on the discharge control panel to stop the discharge process.
If you don’t manually press the discharge button to stop, the discharge
process will continue discharging, even when the mobile holding tank is full.
If wastewater is spilled around the tank, rinse with fresh water and leave the
place tidy.

■ Place the cap on the holding tank.
■ Empty the holding tank at a designated location.
■ If necessary, repeat the discharge procedure until the tanks are completely
discharged.
■ Store the discharge device back in the discharge storage bin (refer to steps
8, 9, 10 and 11 of Discharge the tanks).
