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 rinsed 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 water softener softliQ:SD

Based on the consumption values of the past 4 weeks, the system capacity is automatically adjusted to the individual water consumption of the owner / user. SoftliQ water softeners offer several selection options (= modes of operation). The factory setting is Comfort. In case of considerable fluctuations in the water consumption, however, it is possible to switch to the Power mode in the Settings. With low water consumption, Eco offers an energy and resource-saving option. The currently setting is displayed in Information menu 1.
A regeneration is triggered 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. No later than after 4 days without regeneration, the system releases a complete regeneration, as required by DIN standard 19636-100, for hygienic reasons.
The intelligence of the softliQ water softener allows for an efficient operation at the lowest salt and power consumption possible.

3.4 Function

The water softener softliQ:SD offers 5 selections:
● Comfort (factory-setting)
Optimum use of resources and system output.
● Eco
Minimum use of resources in case of normal consumption.
● Power
Maximum performance for highest demands.
● Individual
To enter your individual user profile.
● Fix
To enter a permanently fixed capacity figure without looking at the past and adjusting the capacity figure.

3.5 Additional equipment softliQ:SD21 and softliQ:SD23

3.5.1 Salt supply display

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 shown by a yellow symbol in the control unit. The control unit of the softliQ:SD21 and softliQ:SD23 calculates how many days the salt supply is expected to last, and shows 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.

3.5.2 Illuminated LED ring

The illuminated LED ring is used as a visual signal in water treatment, operation and fault. In the standard setting, the illuminated LED ring behaves as follows:
● Is illuminated during water treatment
● Is illuminated during operation of the control unit
● Intermittent flashing in case malfunctions do occur
● Intermittent flashing in case of pre-alarm salt supply
The illuminated LED ring can be set to continuous illumination or be deactivated completely (refer to chapter 6.2).

3.5.3 Water sensor

The water sensor detects water at the installation location of the softliQ, provides information via the softliQ control or the Grünbeck myProduct app, and triggers an audio signal (if activated).

3.6 Product registration

You have the following options to register your product:
● Registration on Grünbeck's website (www.gruenbeck.com).
● Registration using the Grünbeck myProduct app (refer to chapter 6.3).
● Registration via the enclosed postcard.
Registration extends your warranty by 1 year.

4.1 Requirements for the installation site

Observe local installation directives, general guidelines and technical specifications.
● The installation site must be frost-proof and ensure the product is protected from chemicals, dyes, solvents and vapours.
● 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.
● Always install a drinking water filter and, if required, a pressure reducer (e.g. fine filter pureliQ:KD) upstream of the product.
● A shock-proof socket is required within a distance of approx. 1.2 m of the system. The socket requires a permanent power supply and must not be connected to light switches, emergency heating switches or similar devices.
● A drain connection (DN 50) must be available to discharge the regeneration water.
● There must be a water withdrawal point near the product.
● A floor drain suitable for the system size must be available at the installation site
or a protection device e.g. protectliQ or a protection device with water stop of the same quality must be installed.
● Ensure that lifting systems are resistant to salt water or use our regeneration water delivery pump (refer to chapter 3.7).

4.3.1 Installing connection block

1. Install the water meter screw connection into the pipe.
2. Check the flow direction given on site.
The direction of flow is indicated by an arrow on the connection block.
3. Make sure that the strainer insert is inserted on the inlet side.
4. Mount the connection block by tightening the union nuts without applying tension.
» The connection block is installed.

4.3.3 Establish waste water connection as per DIN EN 1717

The duct connection facilitates DIN-compliant connection (refer to chapter 3.7).
NOTE: Waste water backing up due to kinked hoses.
● Risk of water damage. ► Run the hoses to the drain with a downward slope and without kinks and bends.
1. Shorten the flushing water hose (diameter 12 mm) to the required length.
2. Fasten the flushing water hose (regeneration water flows out under pressure).
3. Shorten the overflow hose (diameter 16 mm) to the required length.
4. Run the overflow hose to the drain with a downward slope.
5. Make sure there is a free outlet to the drain in accordance with the standard.
6. Fasten the overflow hose.
If the flow pressure is at least 3 bar, the flushing water hose can be routed up to 2 m above the floor. It is then not possible to connect the overflow hose.
» This completes the installation.
Protect the product from contamination until it is started up.
► Slide the protective sleeve from the packaging over the product.
