Regeneration of the system
:
The quantity of calcium and magnesium
ions that the resin may retain is limited;
therefore, the volume of water that a
water softener can treat is limited as
well.
The system must periodically carry
out a process known as regeneration,
which allows the resin to recharge with
sodium ions, so it can continue softening
water. In the Ergo, the regeneration
process starts automatically when the
programmed water volume is achieved.
Regeneration is composed of several
stages, which are described below:
Note: During the regeneration process,
the system will allow untreated water to
pass through, in order to maintain the
water supply.

Rinsing with brine/slow rinsing:
Hard water enters the equipment
through the inlet, flows towards the
compartment of the Venturi tube, which
carries the brine (or sodium chloride
solution) from the brine tank. Brine
flows downwards towards the resin and
then enters the central tube through the
lower distributor.
Following this, the brine flows towards
the drain tube through the drain valve.
The resin beads are replaced by sodium
ions from the brine solution during the
rinsing with brine and the slow rinsing
stages, in order to force the calcium and
the magnesium out of the resin beads.
Subsequent washing:
Hard water enters the equipment
through the inlet of the valve, flows
downwards to the resin bed and the
lower distributor, until the central tube.
Then, the water for the subsequent wash
flows towards the drain tube through the
drain valve.

Refilling the brine tank:
Once the subsequent wash is done, the
brine tank refills with hard water through
the brine valve, in order to prepare the
brine solution for the next regeneration.
A brine level float controls the water
level in the tank. This process is fully
automatic, therefore it is not necessary
to add any water to the brine tank
(except during the start-up, as indicated
in ‘Section 7’).
Note: The brine line is under pressure
when in service. Please check carefully
that there are no leaks in the brine line
during water treatment.
Regeneration degree and capacity:
The exchange capacity is the quantity of
hardness that a certain resin volume can
retain before getting exhausted. This
