Curative descaling (about 10 hours)
If a preventive descaling is not enough to restore the original flow of purified water, it’s necessary to do a curative
descaling.
This operation is the last way you have before having to replace the membrane.
Depending on the membrane’s state, the nominal flow won’t be systematically restored (clogged membrane) or (worn
membrane).
1.
Shut off the tap for purified water.
2.
Disconnect the hose for purified water from the appliance (disconnect before the non-return valve if a storage
tank is installed).
3.
Disconnect the electrical plug and then plug it back again to make the appliance switch to flushing mode.
4.
Let the water purifier flush.
5.
Unscrew the container of filter II as described under “Replacing the filters”.
6.
Put 200gr of OSMONET (the descaling agent) into the container. Fill the container almost to the top with
lukewarm water ( 20° to 40°C). Stir until the powder has dissolved (picture
A
).
7.
Screw the container (filled with the descaling solution) into place with the aid of the filters spanner.
8.
Open the tap for purified water and let RO400C operate for 45 seconds.
9.
While the tap is still open, disconnect the electrical plug. Then close the tap. Don’t touch the water purifier for
10 hours ( for example during the night).
10.
At the end of the 10, unscrew the container. Discards its content and rinse it with water.
11.
Put a filter II in the container; refit and tighten the container by hand.
12.
Connect the electrical plug and let the water purifier finish the flushing operation.
13.
Open the tap for purified water and let the water flow for 10 minutes. Then close the tap. The water purifier
flushes for some minutes.
14.
Connect the hose for purified water to the appliance ( or the non-return valve if a storage tank is installed).
