4.5 Service programs
S1 - Five minutes no flushing
For a manual cleaning of the urinal, the flushing program is deactivated for five min-
utes. Then, a main flush is activated. Finally, the control reactivates the preset flushing
program.
S2 - Intermittent flushing
Flush stop for 2 minutes, e.g. to allow the descaling solution to sit. Then, 5 flush cycles
are started within 10 minutes with a short flush every 2 minutes. The last of the 5 flush
cycles is the main flush. Finally, the control reactivates the preset flushing program.
