Preprogramming start conditions
Periods are used to automatically start the short flush with fresh water and
purification process. See "Periods" on page 58.
The NoNa
+
will not start automatically if there is insufficient water in the
drain water tank. This will trigger an alarm.
Intermittent (acid) cleaning will start automatically once a preset volume of water is
reached. See "Intermittent (acid) cleaning" on page 59.
Maximum inactive duration
In order to keep membranes in good condition, it is necessary to flush them briefly
with fresh water on a regular basis. This is done once every 48 hours as standard if
the system has been idle for that duration of time.
The
Maximum inactive duration
setting is set to 48 hours by default (path:
). If this time elapses, the NoNa
+
will generate an alarm message. The
NoNa
+
will not start automatically.

The alarm screen
The alarm screen lists the following information for each alarm: status, location, time
and corresponding message.
If you tap an alarm, a pop-up appears with detailed information about the alarm. This
is also where you can acknowledge the alarm. Acknowledging an alarm resets it.
However, if the cause of the alarm has not yet been resolved, the alarm will probably
return almost immediately.
