  • Page 12: Functional Description

    Functional description From the reverse-osmosis system (RO system) the fully demineralised water (also called RO water or permeate) is fed via a shut-off valve (18, by client) and a water filter (19, by client) to the central unit (17). In the central unit the RO water is fed via the inlet valve Y1 (13), the conductivity measurement Lf1 (16), and the silver ionisation (15) which degerminates the water and the sterile filter (10) to the valve mani- fold (21) with the spray valves Y5-Y7 (7 control steps), Y5-Y7+Y9 (7 control steps with double stage), Y5-Y8 (15 control steps) or Y5-Y8+Y9 (15 control steps with double stage) and the drain valve Y10.
  • Page 13 Hygiene function/Flushing In order to prevent standing water, each spray circuit which is not active is emptied via the corresponding spray valve (the spray valves are connected to the drain in currentless status). If the conductivity in the water supply line exceeds a preset value or if the humidification system has been without demand for more than 23 hours, the drain valve Y10 opens and the water supply line and the water lines in the central unit are flushed for a certain time with fresh RO water.
