7.2 Flushing the portable toilet

NOTE
Changes in the ambient temperature or the actual height above sea level
while travelling can cause the pressure in the holding tank to rise or fall.
Before use, make sure that the pressure in the holding tank is equalised
by opening and closing the slide valve with the seat cover closed.
➤ Pull out the flush grip to allow the waste to pass into the holding tank (fig. 8,
page 4).
➤ Press the flush button to flush the portable toilet (fig. 9, page 4).
➤ Push the flush grip to close the slide valve.
7.3 Emptying the holding tank
When the filling level display shows "Full", (fig. 0, page 4), the holding tank needs
to be emptied.
➤ Pull the locking grip on the holding tank if the toilet is fitted with the optional
fastening holders. To reach the rear bracket, lift up the toilet and move it.
➤ Pull up the rear latch to disconnect the flush water tank from the holding tank
(fig. a, page 4).
➤ Take the holding tank to a reliable disposal station (or a normal toilet).

NOTE
To protect the environment, never empty the holding tank directly into
the environment, only into an approved disposal station or a toilet.

of the tank.
