14.2 Features
14.2.1 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.
2.
3.
The first phase includes the actual flushing process. The solenoid inlet and drainage valves
are opened at the same time for 30 seconds. The water supply pipes and/or tubes are
rinsed. This ensures that the FIRST water present in the supply line (possibly hygienically
questionable) is not atomised as it is drained directly without filling up the fluid tank. The
flushing volume depends on the pressure of the demineralised water (Fig. 35) and the flush
time (Tab. 13-1).
In the second phase the solenoid valve supply is closed again. The solenoid valve drain
remains open for another 3 min. 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 valve supply opens and the solenoid
valve drain 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 humidifier is determined by the pressure of the
demineralised 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.
