Programme cycle functions
•
Function: After the raw water has flowed through the water softener at a certain pressure and
flow rate, the Na
+
units in the active groups contained in the ion exchange resin are exchanged
for cations contained in the water, such as Ca²
+
and Mg
2+
, so that the concentration of Ca
2+
and
Mg
2+
in the water is reduced and the water is softened.
•
Backwashing: After the ion exchange resin has been saturated, it should be backwashed before
regeneration. This is done to wash out the suspended particles from the water that have settled
and clumped together on the surface of the resin, as well as broken resin splinters. Secondly, a
loosely compacted resin layer favours full contact of the resin components with the regeneration
liquid during regeneration, which creates good conditions for the regeneration of the ion ex-
change resin.
•
Brine and slow brine: Brine at a specific concentration and flow rate flows through the entire ion
exchange layer to regenerate the saturated resin and restore its exchange capacity.
•
Re-fill: Water is poured into the brine tank to dissolve the regenerating salt, produce saturated
resin, and restore the softening exchange capacity.
•
Fast brine: Remove any remaining brine in the resin layer and clean the resin layer until the
outflow is perfect. The resin layer is compressed to achieve the best softening effect.
Creating a saturated salt solution with a uniform concentration
The water in the brine tank is topped up from the bottom and the salt water settles from the top to the
bottom, so that the salt water is mixed evenly by natural circulation and the saturated state can be
achieved more easily.
Reminder feature for low-salt alarm (optional)
If a lack of salt is detected, a low salt alarm is automatically displayed and the user is reminded to top
up the salt in good time. When the user has topped up the salt, he or she can press any button on the
water supply station to stop the low salt alarm (after topping up salt, it takes about 6 hours to clear).
Installation and maintenance
Installation notes
To avoid installation errors, please read the following instructions carefully.
•
As the control components are controlled by electronic circuits, a three-day power failure (72
hours) or an intermittent power supply may cause the time shown on the control valve display
panel to result in an incorrect regeneration time for the water softener (check the time shown
on the control valve panel and the actual time after continuous operation of approximately 3
months). After restoring the power supply, check whether the time displayed on the control panel
is correct. If this is not the case, refer to the instructions for the control valve to find out how to
set the water softener clock.
•
If the water pressure of the water softener is lower than the specified operating pressure, install
a booster pump, which should be installed at the front of the water inlet of the water softener.
At the same time, the outlet pressure of the booster pump must not exceed 4.5
bar, otherwise
a pressure-reducing valve must be installed between the booster pump and the water softener.
