Regeneration
The regeneration phases run one after one, as follows :
1.
backwashing:
during this phase, the water flush from the bottom to the top of the column,
lifting the resins which are mixed together and release the solids trapped on surfaces of
the resins bed during the service. The backwashing water flows to drain from the top of
the column. This is the only phase, during which the water crosses through the column
from the bottom to the top. During this phase, it is very important to check that there is no
leakage of resins to the drain
.
2.
brine drawing:
during this phase, a concentrated solution of water and sodium chloride
(common kitchen salt, in grain or, better, tablet) is drawn from the brine tank to the resins
column, by an injector. The brine crosses through the column from the top to the bottom.
3.
slow rinse:
it is the first step of the rinse, during which the ion exchanges between
sodium chloride and resins is featured. The time of this phase is not adjusted, since it
starts when the brine tank is completely empty (all brine has been drawn); a special
device built-in the brine float valve avoids the air drawing.
4.
fast rinse:
it is the phase during which the residual of salt is flushed away through the
resins; at the end of this phase the resins column is ready to start again a new service
cycle.
NOTE: During the fast rinse phase the unit supplies the water to the brine tank, in order to
prepare the brine for the following regeneration. The brine tank refill will be
automatically completed when the level mark of water reaches the float valve inside
the tank.
NOTE : During regeneration, (except for "fast rinse" phase) the system supplies non
softened water thanks to a by-pass inside the automatic valve; for AM/METER and
AM/RMETER series, water supply during regeneration is completely inhibited by
means of a membrane valve mounted on the outlet.
See programmer manual for the time of each phase of regeneration.
