3.3 Functional description
3.3.1 Ion exchange process
The softliQ water softener works according to the ion exchange process. The exchange of
calcium and magnesium ions for sodium ions causes the water to become soft.
Figure Explanation
The exchanger contains ion exchanger resin in the form of small resin
beads.
Sodium ions adhere to each resin bead.
Hard water containing lots of calcium and magnesium ions flows through
the exchanger.
The ion exchanger resin absorbs calcium and magnesium ions from the
water in exchange for sodium ions.
This reaction is called ion exchange.
The calcium and magnesium ions are retained in the exchanger.
Soft water without calcium and magnesium ions, but containing sodium
ions, leaves the exchanger.
This process continues until no more sodium ions are available. The ion
exchanger resin is exhausted.
The exchange can be reversed if a large amount of sodium ions is
added.
The exchanger is flushed with brine (water containing salt).
By their sheer number, sodium ions displace calcium and magnesium
ions on the ion exchanger resin.
This water containing calcium and magnesium ions is discharged to the
drain.
The initial condition is restored.
The ion exchanger resin is regenerated, and thus ready for operation.
Sodium ion Calcium ion Magnesium ion
Your dishwasher works according to the ion exchange process, too.

3.3.2 Intelligence of the softliQ:SC water softener
Based on the consumption values of the past three days, the system capacity is
automatically adjusted to the individual water consumption of the owner/user. The water
softener softliQ:SC offers two selections. The energy and resource saving Eco Mode is set
by the factory. In case of considerable fluctuations in the water consumption, however, it is
possible to switch to the Power mode in the settings menu. The currently set mode is
displayed in Information menu 1.
A regeneration is released daily, if at least 50 % of the current system capacity is used up.
The point of regeneration automatically is placed in a time period where usually no water is
consumed. The point of regeneration can also be set at a fixed time. Should water be
required during the regeneration process, non-softened water is available.
During each regeneration, only the used-up system capacity is regenerated and only as
much salt is used as necessary. For hygienic reasons, the system releases a complete
regeneration after four days at the latest, as required by DIN standard 19636-100.
The intelligence of the softliQ water softener allows for an efficient operation at the lowest
salt and power consumption possible.
3.4 Response behaviour
● Eco mode
Resource and energy-saving operating mode for households with a consistent
withdrawal profile.
● Power Mode
Optimised provision of soft water for households in which the withdrawal profile
fluctuates considerably.
3.5 Optional features for softliQ:SC23
3.5.1 Pre-alarm salt supply
Once per regeneration, a light sensor briefly checks the filling level of the regeneration salt. If
the filling level is below the minimum, the control unit provides feedback in the form of a
warning message. This is indicated by a yellow symbol in the control unit. After the minimum
filling level is being undershot, the control unit of the softliQ:SC23 calculates how many days
the salt supply is expected to last, and indicates this value in days in the warning message.
The days the salt supply is expected to last are calculated based on the water consumption
of the past days. In case of fluctuating water consumption, the indicated range of the salt
supply also fluctuates.

BA_TD3-BS000en_074_softliQ-SC.docx

system and may only be performed by a specialist installer.
Item Designation Item Designation
1 Safety device protectliQ 2 Drinking water filter pureliQ
3 Garden water pipe 4 Insulation set softliQ:SC
5 Water withdrawal point 6 EXADOS dosing computer
7 Drain connection DN 50 acc. to DIN EN 1717
5.1 Requirements in relation to the installation site
Observe local installation directives, general guidelines and technical specifications. The
installation site must be frost-proof and ensure the system's protection from chemicals, dyes,
solvents and vapours.
Always install a drinking water filter and, if required, a pressure reducer (e.g. fine filter
pureliQ:KD) upstream of the system. A shock-proof socket is required within a distance of
approx. 1.2 m of the system. A drain connection (DN 50) must be available to discharge the
regeneration water.
Note: The system will not function without continuous power supply.
● No soft water will be available if the system is operated without electricity.
► Do not interconnect the socket with a light switch, heating emergency switch or
the like.

NOTE: The valves of the system are operated electrically.
● Water can flow to the drain unchecked if there is a power failure during
regeneration.
► If there is a power failure, check your product and shut off the water supply, if
necessary.
NOTE: Malfunction of the lifting system if there is a power failure.
● Water damage in case the lifting system fails
► Secure your water installation against inadvertent water leakage if there is a
power failure.
The installation room must be provided with a floor drain. If no floor drain is available, an
appropriate safety device has to be installed to prevent water damage. We recommend
using a protectliQ safety device (refer to chapter 3.7).
If the softened water is intended for human consumption in the sense of the German
Drinking Water Ordinance, the ambient temperature must not exceed 25 °C. For applications
that are purely technical, the ambient temperature must not exceed 40 °C.
Downstream of the system, a withdrawal point for cold water must be available in close
proximity.
NOTE: Functional failure if lifting systems are not resistant to salt water.
● Water damage in case the lifting system fails
► Use a salt water-resistant lifting system or our regeneration water delivery pump
(refer to chapter 3.7).

7.4.1 Taking a water sample
Note: If the flow rate is too low during the sampling, the result will be falsified.
● The system will be programmed with incorrect values for the raw water hardness.
● The required soft water value will not be attained.
► Fully open the water withdrawal point for cold water or the sampling valve. A flow
rate between 0.4 m³/h and 0.6 m³/h must be attained.
► When taking a soft water sample, the flow rate can be read in information level 2.
1. Open a water withdrawal point for cold water.
a In order to take a raw water sample, use a water withdrawal point for cold water
upstream of the system.
b In order to take a soft water sample, use a water withdrawal point for cold water
downstream of the system.
2. Let the water run for at least 30 seconds.
3. Take a water sample with the test tube:
a Fill the test tube up to the °dH mark to determine the water hardness in °dH.
b Fill the test tube up to the marking °f (x 0.1 = mol/m³) in order to determine the
water hardness in °f, mol/m³ or mmol/l.
7.4.2 Determining the water hardness in °dH/°f
1. Add one drop of titration solution (1 drop = 1 °dH or 1 °f).
2. Shake the test tube until the titration solution is mixed with the water.
3. In case of red colouring, repeat steps 1 and 2 and count the drops until the colour
changes to green.

BA_TD3-BS000en_074_softliQ-SC.docx
» If the colour changes to green, the water hardness has been determined.
The number of drops corresponds to the degree of hardness in °dH or °f.
Example:
Test tube filled up to the °dH mark: 6 drops = 6 °dH.
Test tube filled up to the °f mark: 6 drops= 6 °f.
7.4.3 Determining the water hardness in mol/m³ (mmol/l)
1. Determine the water hardness in °f as described.
2. Divide the °f measured by 10.
The water hardness in °f divided by 10 corresponds to the degree of
hardness in mol/m³ (= mmol/l).

13 Other information
13.1 Explanation of terminology
System capacity
Indicates the quantity of fully softened water that the water
softener can produce.
Regeneration water
After the regeneration, this water is saturated with calcium
ions and is flushed out of the system into the drain.
Raw water
Raw water is the untreated water before it passes through
the water softener.
Drinking water
Drinking water is any water that is intended for use in the
domestic environment for drinking and all other food
preparation purposes, for personal hygiene and cleaning as
well as for cleaning objects that do not only temporarily
come into contact with foodstuffs or the human body.
Turbine water meter
A very small turbine fitted in the system which transmits
pulses to a sensor by means of a magnet, thereby allowing
the water flow rate through the system to be measured.
Fully softened water
Water with a residual hardness of 0 °dH (0 °f).
Soft water
Soft water is the general term for softened water. It is also
referred to as decalcified water.
Page 65
Other information
65 | 76
BA_TD3-BS000en_074_softliQ-SC.docx
13.2 Sodium content in the water
When softening water by 1 °dH (0.18 mmol/l), the sodium content increases by approx.
8.2 mg/l. The German Drinking Water Ordinance specifies that the sodium content of
drinking water must not exceed 200 mg/l. Select a soft water hardness with a sodium content
less than 200 mg/l.
The local water suppliers will inform you about the sodium content of your raw water.
Sample calculation:
Raw water hardness: 28 °dH (50 °f, 5 mmol/l)
Sodium content in the raw water: 10.5 mg/l
Admissible increase of the sodium content by softening:
● 200 mg/l - 10.5 mg/l = 189.5 mg/l
● 189.5 : 8.2 = 23 °dH (41 °f, 4,1 mmol/l)
The raw water hardness may be reduced from 28 °dH (50 °f, 5 mmol/l) to 5 °dH (9 °f,
0.9 mmol/l).
13.3 Hardness ranges
The hardness ranges were classified according to the German Act on Detergents and
Cleaning Agents published in 2007.
Hardness range °dH °f
Soft < 8.4 < 15
Medium 8.4 – 14 15 – 25
Hard > 14 > 25
► When dosing cleaning agents, take the new hardness range of your water into
account.
