12.2 Features
12.2.1 Flushing of water supply line
The humidifier goes into flushing mode, which is carried out in two phases depending
on the time, for the following events:
1.
Initial start-up (operating voltage is present for the first time)
2.
Operating voltage is applied again (after each interruption of operation voltage)
3.
After each humidifying pause which is longer than the AquaDrain cycle
The first phase
includes the actual flushing process. The solenoid inlet and drainage
valves are opened at the same time for 160 seconds. The water supply pipes and/or tubes
are rinsed. This ensures that the FIRST water present in the supply line (possibly hygieni-
cally questionable) is not atomised as it is drained directly without filling up the fluid tank.
The flushing volume depends on the pressure of the pure water (fig. 24).
In the second phase
the solenoid inlet valve is closed again. The solenoid drainage valve
remains open for another 160 s to ensure that the water that might still be inside the fluid
tank is drained.
If a humidification request is made after the two-phase rinse operation, the humidifier will
go into normal operation. At the same time, the solenoid inlet valve opens and the solenoid
drainage valve closes. The fluid tank is filled up to maximum level. After that, provided that
all internal and external safety elements allow for operation, humidification starts.

* The filling time for the fluid tank of the NKBD is determined by the pressure of the
pure water.
If no humidification request follows after the two-phase rinse operation, the humidifier will
go into standby mode until a humidification request is carried out.
