Introduction

Thank you for choosing to purchase this quality product. To minimise the risk of injury, we ask you to always take some basic safety precautions when using this product. Please read this operating manual carefully and make sure that you understand it. Keep these operation instructions in a safe place.

Use and warning notices

• Installation, commissioning, or maintenance of this water softener must be carried out by qualified personnel.
• Liability for consequences caused by improper installation is excluded.

Safety instructions

• The water softener can only be supplied with 12 V and 1500 mA. Observe all safety precautions in connection with the operation of electrical appliances during operation and maintenance.
• If the mains cable of the water softener is damaged, it must be repaired by a qualified electrician.
• The water softener is only suitable for filtering pre-treated tap water. It cannot be used to filter water with an unknown level of contamination or an unknown proportion of harmful organisms.
• The water softening liquid cannot be drunk directly. Do not drink it directly.
• Do not block the overflow pipe and the drain pipe of the water softener.
• Do not place any objects on the water softener. · Do not immerse the water softener in water.
• Do not use the water softener outdoors or in direct sunlight. · The temperature of the water entering the treatment device must not exceed 38.
• After the water softener has been out of operation for a certain period of time, manual treatment must be carried out before reuse to ensure the quality of the water produced.
• The power supply must not be interrupted while the water softener is in use in order to avoid timing errors of the water softener, which would affect the originally set regeneration start time of the water softener. Otherwise, users could misuse water that has not yet been softened.
• If the water consumption increases significantly (compared to normal consumption) or the hardness of the raw water increases, the regeneration cycle must be shortened accordingly or the hardness of the raw water must be adjusted so that the regeneration times are extended.
• As hot water can severely damage the internal treatment system, it should be ensured that there is a connecting pipe of at least 3 m in length between the outlet of the softener and the inlet of the hot water boiler. If the 3-m connection line cannot be assured, it is recommended to install a non-return valve between the water softener and the hot water boiler.
• The permissible ambient temperature of the system is 5­40. The ion exchange resin in the housing can easily freeze and break. If in doubt, take suitable frost protection measures so that the resin is not affected.
• During operation of the water softener, shocks to the water must be avoided, e.g., by quickly opening or closing the valve and switching off the water pump in emergencies.
• Do not apply force to the machine and avoid direct sunlight and exposure to heat from other sources.

Functionality

Functions and features

Automatic operation

• The built-in time control has a 24-hour time control and can automatically calculate and regenerate the amount of renewable water according to the set resin capacity, raw water hardness, and regeneration coefficient. This happens when the remaining amount of water produced drops to zero and the regeneration trigger time has been reached (the factory-set time is 2 a.m.). Regeneration can also be initiated after the set regeneration interval days have elapsed if the remaining water production is not zero and the set regeneration trigger time is reached (factoryset to 2 a.m.).
• The control system can calculate and design an economical and effective soft-water treatment scheme according to the actual water supply and water consumption of the users.

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 Mg2+, so that the concentration of Ca2+ and Mg2+ 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 exchange 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.
  WilTec GmbH is not responsible for detrimental effects and damage caused by an excessively high outlet pressure of the booster pump on the water softener.

• If the main water supply is interrupted, the main valve of the supply line should be closed immediately or the bypass valve of the water softener should be switched to the bypass station to prevent the water softener from being damaged by the negative pressure in the pipework caused by the municipal water supply.

• When the main water supply is restored, a large number of pollutants in the water pipe contaminate the treatment device. Therefore, first switch the bypass valve of the treatment device to the bypass station, open the tap in the house, and drain the water from the dirty water supply station.

• The water softener must not be tilted or laid on its side during transport, installation or use.

• The floor on which the water treatment device is installed should be level and have a loadbearing capacity of more than 300 kg/m. In addition, an AC power supply, a water inlet and outlet interface, a waste water pipe, and a floor drain should be available.

• Installation area:

  • SOFT-V1: 380 × 550 × 690 mm (L×W×H)
  • SOFT-V2: 380 × 550 × 1150 mm (L×W×H)

• Do not install the softener near acidic and alkaline substances or near gases to avoid corrosion on the softener.

• The water softener must be installed indoors. Measures must be taken to insulate the housing and pipework, in particular to protect against frost and solar radiation and for sealing.

• It is forbidden to install the softener on a water pipe with a water pressure of more than 4.5 bar. If the water inlet pressure exceeds 4.5 bar, a pressure-reducing valve must be installed (to be purchased separately), otherwise the company accepts no responsibility for consequences such as impairment or damage to the water softener due to excessive water inlet pressure and any resulting damage.

• The water softener should be installed and used in a room with a floor drain and smooth drainage. If the drain pipe or floor drain is blocked and the drain pump cannot drain normally due to a power failure or other malfunction, please close the building’s main water inlet valve immediately. At the installation site, it must be ensured that objects in the neighbouring area or in the part of the building below are not damaged or flooded if water escapes from the water softener or the connection pipe.

• As shown in the illustration below, the drain pipe and the overflow pipe must be secured with ring clamps to prevent leakage during water drainage.

• Before connecting the water supply pipe, remove any dirt and dust remaining in the pipe. Then close the main valve before connecting the system.

• The overflow and drain pipe must be provided with a free pipe guide. The length of the pipe may not be increased and the pipe diameter may not be reduced without authorisation.

• For the pipe connection, the pipe should be as close to the wall as possible, the pipe should run straight, and the angles should be free. After installation, the pipe should be fixed to the wall with a ring clamp. Pay attention to the height and placement angle of the pipe when it is connected. There should be no obvious stresses after connecting the pipe to avoid water pipe bursts and water leakage from the treatment device or pipework due to stresses in the pipework during long-term use.

• It is forbidden to combine the overflow and drain pipes in one pipe and insert it into the wastewater outlet.

• If the waste-water pipe or floor drain is blocked, the water softener must not be used. · After installation, check whether water is leaking from the connection nozzles, the connection
  between the control valve, and the GRP tank (glass fibre plastic) and the bypass connection, and whether the water level in the brine tank is rising. · Seals are usually installed when connecting threaded parts. It is therefore not advisable to apply too much force, as this can easily lead to the thread slipping and cracking. · The waste-water pipe must be level and there must be an air gap between the waste-water pipe (overflow pipe) and the waste-water outlet. · The waste-water pipe (overflow pipe) must not be connected to the sewage system in a sealed manner, as otherwise the machine can no longer work normally or the waste water can no longer flow back to the machine due to the negative pressure.

Installation

The water softener must be installed, tested, and put into operation for the first time by a specialist. The following installation steps are only intended as a guide (using a PPR pipe as an example).

1. Install the water-inlet and -outlet pipes on the wall according to the actual height of the product above the floor (sold separately).

14. Treatment of bypass valves in special cases: In the event of a failure of the device or other special circumstances, the bypass valve of the machine can be set to the bypass state (push the pull rod to the operating position as shown in Fig. 3). You can temporarily use the municipal water supply directly. Once the fault or problem has been rectified, set the bypass valve to the operating position (push the pull rod to the position shown in Fig. 2) to restore the soft water supply

15. Bypass valve with water mixing function (depending on model) ­ The further the water mixing regulator is turned clockwise, the greater the proportion of mixed water and the higher the degree of hardness of the outgoing water.

21. The general installation scheme is divided into two installation methods (as shown in the figures below).

22. Transformer

If an operating room is available, it is recommended to use the installation method shown in Figure 5. Otherwise, only the drain pipe and the overflow pipe can be inserted into the floor drain. As shown in Figure 6, make sure that the two pipes are fixed to the wall to prevent the pipe from being flushed out of the floor drain when emptying. This can have detrimental effects and lead to damage.

Install connections

• The connection and laying of the pipe system is carried out in accordance with the provisions of the construction standards for water supply and drainage pipes. The inlet and outlet interfaces of the water softener and the water pipe interfaces are connected by a ¾ PPR inner pipe or a corrugated pipe and must be installed on the same axis (see installation plan). The inlet and outlet points must not be installed in reverse.
• Connect the water inlet and outlet pipes, the drain pipes, and the overflow pipes in sequence to ensure that all connections are tight and that there are no leaks. It is recommended to use flexible pipes to connect the water softener inlets and outlets, the drain, and the overflow (note: 304 stainless steel, alloy forged steel, high-strength engineering plastics, and other materials are to be used for the connection of pipe fittings and valves; valves and pipe fittings made of iron are strictly prohibited).

Installing the drain and overflow pipes

• First loosen the clamp and insert it into the prepared pipe, then insert the pipe into the drain and overflow connection to the floor, and finally turn the clamp onto the connection of the pipe, drain, and overflow connection and tighten it firmly. The drain and overflow pipe must be secured with a clamp. (Note! This procedure is intended to ensure that the hose is not pushed away or pushed out of the sewer if the flat is connected to the sewer or the water pressure of the floor
  drain is high).

• The position of the control valve must be higher than the floor drain and the length of the drain and overflow pipe must not exceed 2 m. The installation of shut-off devices in the drain pipe is strictly prohibited. The sealing of the pipe fittings may only be made of PTFE.

Instructions for first use

1. Initial settings of the operating system
   When the softener is switched on for the first time, the system indicates that water is being added. Press the button to access the operating system and set the current time, the regeneration time, and the raw water hardness.

2. First water supply for water softeners
   Before the first water supply, close the water inlet valve of your building, switch the bypass valve to the operating position and to the unlocked state, press the button to start regeneration; “system is back washing” is shown on the display panel. When the power is switched off, the water softener remains in backwash mode. Open the water inlet valve slowly to ¼ (opening it quickly can damage the appliance and lead to resin loss). At the beginning, the sound of slowly escaping air should be heard in the blow-off pipe. After the air in the GFK tank has escaped (i.e., when the water in the blow-off pipe flows out evenly), the water inlet valve should be fully opened.
   Attention! If the water inlet valve is fully opened directly, the water will flow into the softener too quickly, causing the softener resin in the tank to be stirred up, which will easily cause the upper collection tank to break and damage the softener. It is therefore necessary to open the water inlet valve slowly ¼ to allow the water to flow slowly into the tank, release the air in the tank and fill the tank with tap water. During backwashing, the outlet of the blow-off pipe must be checked several times until it is really clean. The backwash time should not be less than 5 min.

3. First filling of the brine tank with water After completing the above steps, switch on the system. Press to call up the brine and slow rinse option, then press once to call up the refill option. In the refill option, a certain amount of water is added to the brine tank so that the appliance has ready-to-use brine available for the next regeneration. Once refilling is complete, the system switches to the quick-rinse option, in which it takes around 5 min for the discharge to be recognised. Once the hardness has been determined, proceed to the next step and return to the operating option to produce softened water.

4. Salt addition to the brine tank and salt addition process Open the lid and pour a sufficient amount of soaked salt into the brine container. The salt in the brine tank must be above the water level. As a rule, the salt should exceed the level of the water in the brine tank and salt particles should always be visible.

5. First complete regeneration
   Once the above steps have been completed, the water softener must stand for 6 hours so that the salt particles filled into the brine tank can dissolve sufficiently and a sufficiently concentrated brine is produced. In the unlocked state, press to start regeneration so that the system runs automatically and performs a complete regeneration. During this process, the water and electricity must not be switched off and no buttons must be pressed.

6. First use

Maintenance

Please check the water softener regularly and see

• if there is a water leak in the water softener pipe or if water is seeping through ­ if this is the case, contact a specialist;
• if the overflow pipe is blocked ­ if this is the case, remove the blockage in good time;
• if the salt container is vertical ­ align it correctly in good time (as shown).

The recommended service life of the ion exchange resin is 5­10 years. It should be replaced regularly according to the local water quality and actual water consumption. As the product is updated regularly, the actual product may differ from the instructions.

Note! As the pressure in the water pipe fluctuates (the water pressure is generally higher at night than during the day), it is advisable to check the individual connections for leaks two days before installing and commissioning the appliance.

Function and meaning of the control panel
The functions and parameters of the water treatment device are set both in the foreground and in the background. The foreground mode is intended for users. Only the current time, the regeneration time, the raw water hardness, and other parameters can be set. The background mode is set by the manufacturer at the factory, e.g., backwash, brine and slow rinse, refill, quick rinse, wash time, etc.

Operation and troubleshooting

Once the system has been set up and you have carefully read the parameter settings and instructions, switch on the power supply. The display panel lights up, and “12:12” flashes. Set the current time according to the setting method in the table below. Once you have set the current time, go to the settings menu where you can set the “Regeneration time setting” (the default setting is 2:00 am and does not normally need to be changed) and the “Raw water hardness setting” (to determine the raw water hardness, see the “Water hardness and testing” section).

Once the water softener has been installed, the three parameters shown above must be set.

Water hardness and testing

Total water hardness
The total water hardness results from the total content of calcium and magnesium ions in the water, including the carbonate hardness (i.e., the calcium and magnesium ions that can be excreted as carbonate by heating, therefore also referred to as temporary hardness) and the non-carbonate hardness (i.e., the proportion of calcium and magnesium ions that can no longer be excreted after heating, therefore also referred to as permanent hardness).

Testing the raw water hardness
Immerse the reaction zone of the hardness-test paper in the liquid to be tested for 2 s. Remove and wipe off the excess water droplets. After 15 s, compare the colour with the colour chart. The colour is close to the concentration value. Make a note of the measured value for later use.

The hardness expressed by the CaCO content can be roughly divided into

After setting the parameters, switch on the water inlet switch and observe the operation of the water

softener. In the water-supply position, press the button so that the machine automatically switches to service mode to rinse the resin. At the same time, check that no water is leaking from the individual components and that no resin is leaking. During normal use, the user does not need to carry out any further work on the softener, but simply needs to add a certain amount of salt to the brine tank at regular intervals.

Troubleshooting table

If the water softener does not work, please check if there is a problem with the water supply or the power supply (see table). — If the water softener is leaking, please close the tap water valve connected to the water inlet of the water softener.
