● Pour the solution through the filter and the resin,
letting it flow down freely.
● Wait about 5 minutes, then hold the softener under
a tap and rinse it with water. When the water coming
out of the softener is no longer salty, the resins are
regenerated and the softener is ready for use once
again.
● Put the softener back on the rubber tube and
replace it horizontally on the bottom of the tank.
● On completion of this operation, the machine can
be started up again by repeating the procedure
described in paragraph 7.3.
