  • Page 5: Introduction To The System

    NTRODUCTION TO THE SYSTEM 3.1 I NTRODUCTION The water purifier system «O maxi+» produces water of Class 2 as defined in ISO 3696 standard, which is intended to be used by clinical analyzers. The principle of purification uses two technologies: the REVERSE OSMOSIS, which is currently the most effective membrane separation process, the demineralization by ion exchange resin.

    General comments on the calibration of the conductivity electrodes The calibration process is not forced by the system. It is possible to adjust the displayed value on the controller’s screen if it is different from the value measured with an external calibrated conductivity meter. For the calibration of the electrodes, it is necessary to use a precise external conductivity meter which must be calibrated (in option, conductivity meter reference 950026).

    6.4 M AINTENANCE PROCEDURES Flow measurement procedure 6.4.1.1 General points The flow measurement is interesting to check the filters and reverse osmosis membrane plugging state. The osmosis membrane flow is function of the supply water temperature. We generally allow a flow drop of 3 % per Celsius degree in a range from 10 to 25 °C. This flow measurement must be compared to the water purifier theoretical nominal value with a fixed temperature, which is 25 °C: Note: this theoretical flow rate represents the production at a "tank outlet"...
