4.3 Functions of the Appliance
How the Appliance Works
Hard water contains a combination of calcium (Ca), magnesium (Mg) and iron (Fe).
Softening is used to remove positively charged ions using an ion exchange resin.
When the ion exchange resin loses its effectiveness, it is activated through a
regeneration process.
Regeneration
Regeneration is carried out by rinsing the sludge with a salt solution and flushing
the absorbed calcium and magnesium ions into the wastewater.
Regeneration is carried out automatically in an intelligent, logical way: based on the
water consumption of the previous 7 days, the system itself selects the day of
regeneration at the set time. During regeneration (60 min), unsoftened water is
available.
The regeneration process consists of 4 cycles:
1. Regenerating agent replenishment
2. Rinsing with the regenerating agent solution
3. Backwashing
4. Quick rinsing
Water Softening System Structure
The system is configured for 0.7 kg of regenerating agent per regeneration. The
amount of water softened between regenerations is calculated with the formula:
Z = 1350x10 / Y
Z—means the amount of softened water between regenerations,
Y—means the hardness of the tested water based on dH (German degrees of
hardness).
Example of calculation of the amount of softened water between regeneration
processes:
The tested water hardness is 15°dH.
The amount of water Z between regeneration processes is calculated as follows:
Z = 1350 x 10/15 = 900 litres.
With a water hardness of 15°dH, 900 litres of softened water will be obtained.

Standards, Rules and Regulations
•The water used to supply the appliance must be of drinking water quality and
conform to the requirements of the regulations for the use of water of the public
utility at a site.
•All parts in contact with the treated water must be made of waterproof material.
•Ensure that a soil drainage is installed at the water treatment site. The
purchaser is responsible for the drainage.
•The maximum temperature of the supplied water should not exceed 30°C.
•Do not remove the water softening system during use.
•Do not open the water softening system, otherwise the warranty will be voided.

Control Function
Control Valve
Before starting, set the current time and water hardness in degrees.
The valve is set by default to regenerate at 2:00 AM at 20 German degrees.
Salt Replenishment Reminder
The system automatically detects the salt level in the brine tank each time after
regeneration. If the salt level is below normal, the low salt sensor will relay this to
the intelligent control system, and a "SALT" alarm will be displayed in the screen.
The buzzer will sound daily from 7:30 PM to 10:30 PM to remind the user to
replenish the salt.
Salt should be replenished on time to avoid using unsoftened water. When the
display shows the "SALT" alarm, the salt in the brine tank can be used for 2 or 3
more regenerations.
Bypass
The bypass connection allows for convenient installation and maintenance. There
are three different types of states when the bypass handle is rotated.

DRY Brine Tank
The system fills the brine tank each time just a few hours before regeneration to
keep the brine tank largely dry, preventing salt from accumulating above the tank or
leaking out.
INTELLIGENT Control
•The water softening system is equipped with the latest intelligent control valve,
described below.

Technical Data
14 / 30 109901
EN
Upflow regeneration system. Unlike downflow systems, a water softening
system with the upflow system directs the water flow upward. Water flows from
the bottom of the brine tank in an upward swirling motion through the resin. The
upflow system is a high-efficiency system. Thanks to regeneration with the water
stream directed upward, the system can use 30% less salt.
Proportional regeneration. The system regenerates the used resin only
according to the water consumption condition. This saves salt and keeps the
resin fresh.
Holiday mode When the system is not going to be used for a long time, the
holiday mode can keep the resin fresh. Holiday mode can be activated by
pressing and holding the button in softening mode until HOLIDAY appears
in the display. To switch the holiday mode off, press the button until the
HOLIDAY message is no longer displayed.
•If the control valve does not detect water consumption greater than 6 LPM (litres
per minute) or 85 LPD (litres per day) in the next 4 days, the control valve will
initiate 100% regeneration at the set time of the 4th day, and then remain in
standby mode in the operating position.
•If the control valve does not detect water consumption greater than 6 LPM (litres
per minute) or 85 LPD (litres per day) in the next 4 days, the controller will only
perform a 5-minute backwash and quick rinse at the programmed time on the
2nd and 4th day, respectively.
•If the control valve detects water consumption greater than 6 LPM (litres per
minute) or 85 LPD (litres per day), the holiday mode is discontinued and the
control valve switches to normal mode based on previous conditions. The
amount of water consumed is added via the control valve to the records.

Water Softening System Installation
1. After preparation for installation, place the appliance in the designated room
according to the installation plan.
2. Connect all supply and drain lines. The appliance's connections are shown in
the following figure:
Fig. 4
–Connect the water supply line (2) and drain pipe (1) to the appliance.
–Connect the flexible sewage pipe (1/2") to the connection pipe (5) and to
the drain or sewage system.
ATTENTION!
The sewage pipe must be large enough to allow 5 l/m of rinse water to
drain. The drain pipe must be rigid enough not to break and lead to
blockages and overflowing of the brine tank, as well as to the malfunction
of the regeneration process.
–A mechanical fine filter should be installed in front of the water softening
system to protect the appliance from mechanical damage caused by
sediment from water pipes.
–Fill the brine tank of the water softening system with salt tablets.
–Then add 3 litres of water.
–Check all connections to the appliance and tighten them if necessary.
–Connect the water softening system to a single grounded outlet.
