Page 11: Functional Description
Functional description From the reverse-osmosis system (RO system) the fully demineralized water (also called RO water or permeate) is fed via a shut-off valve (18, by others) and a external water filter 5 µm (19, recommended, option or by others) to the central unit (17). In the central unit the RO water is fed via the inlet valve Y1 (11), the conductivity sensor Lf1 (14), and the silver ionization (13) for disinfecting the water and the optional sterile filter (9) to the valve manifold (25) with the spray valves and the drain valve Y10. - Page 12 Monitoring The inlet pressure and the nozzle pressure are monitored with the analogue pressure sensors "PS4" and "PS5". On systems type B without booster pump and without optional sterile filter the nozzle pressure is equal to the inlet pressure, thus the pressure sensor "PS5" is not present. The pressure after the optional sterile filter is monitored with the pressure switch "PS2"...

Page 49: Total System Maintenance
6.2.2 Total system maintenance The frequency of the implementation of a total system maintenance depends on the operating conditions. The state of the humidifier‘s hygiene and its components mostly depends on the quality of the humidifier water, the performance (and the frequency of replacement) of the filter installed before the unit, the air velocity, the air temperature, and the microbiological and chemical composition of the inlet air. - Page 50 In the event of bacterial count concentrations above the limit of 100 cfu/ml, the water supply/water pipes must be subject to a microbiological inspection and appropriate action must be taken immediately (please contact your Condair representative). Bacterial count concentrations in the upper area of the permitted range may be an indication of the onset of bacterial problems in the water supply.
