6.4.2.3.2 Measurement
Switch on the water purifier.
Let flow the water during 15 to 30 seconds.
Remove the conductimeter’s cap.
Rinse the cap and the conductimeter probes with the purified water.
Fill the cap entirely with purified water and plunge the conductimeter in it: the displayed value is
the conductivity in µS/cm.
Repeat the operation 2 or 3 times and retain the value of the last measurement.
Switch off the conductimeter and put back the cap on the conductimeter.
6.4.2.3.3 Interpretation
If the “membrane outlet” conductivity measurement is above 25 µS/cm, it is necessary to replace it
(see paragraph 6.4.7) as well as the flow restrictor (see paragraph 6.4.8).
6.4.2.3.4 Restarting
Close the storage tank valve.
Disconnect the pipe with its closed valve and put back the oulet connection pipe of the storage
tank.
Open the storage tank valve.
Open the tap water valve. The water purifier is operational again.
