3. How does the water softening device work?
Hard water containing iron and manganese flows through the main supply line into your
home.
This water is passed into the water softening appliance which flows through the ion ex-
changer, which softens the water. The treated water then flows into the water system in your
house. An individually programmed softener controls the remaining amount of water for
treatment.
After reaching the ion exchange capacity of the ion exchanger, the device is automatically
revitalised with prepared saline solution (saline solution in the brine tank). During the
revitalisation, the device replenishes the programmed amount of brine in the ion exchanger.
This "recharges" the ion exchanger with sodium ions again. The rinsed-out water from the ion
exchanger is discharged into the sewage system. During rinsing. During the revitalisation pro-
cess, the appliance regains its ion exchange capacity and can treat water again. This revitalisa-
tion process allows you to use the water treatment system for a long time.

5. Overall View of the water softener appliance
1
The control system is the most important part
of the softening appliance. Its functioning
technique is based on ceramic plate technol-
ogy, which is dependent on the relative posi-
tion to one another, which generate succes-
sive work and revitalisation cycles.
The water softener is factory-ready and will
work immediately after connection. Only the
time of day, the water hardness and the revi-
talisation time have to be entered.
2
The bypass is another important element that
accomplishes several important functions in
the operation of the water softening system.
Thanks to this bypass, it is possible to quickly
and easily remove or add the water softener
in to or out of the existing water installation.
In addition, you can adjust the water flow in
the system, so that softened water or normal
tap water flows through. The bypass can also
handle mixing functions.
3
The tank is filled with a filter which allows ion
exchange. For optimal operation of the device,
the filter should be replaced at least every 10
years (depending on the water quality and
water hardness).
4
The body of the appliance is made of durable, flexible plastic. It acts as a salt and brine tank.
Inside there is mounted a cylinder with a filter, an ion exchanger and a float valve. Check and
control the level of the brine in the tank - Protect the unit from overfilling. There is an over-
flow pipe on the side wall of the housing.
5
The float valve regulates the refilling process of water and supplies the saline solution. Proper
functioning ensures the correctness of the revitalisation process.

6. Installation
TO BE PERFORMED BY AUTHORIZED PERSONS ONLY
After unpacking the device, you must remove the power pack and the bypass valve from the
salt container and remove the protective film from the device. Use the special cutouts in the
housing to lift and move the device.
The device must not be lifted by the cable, control head or supply lines. This can cause dam-
age.
Before installation, make sure that the water pressure is higher than 2.0 bar and less than 6.0
bar. If the pressure is higher, a pressure reducer must be installed in front of the device.
If possible, choose an optimal location near your water connection and sewer drain. A con-
stant power supply is required to control the system.
The floor should be stable to support the water-filled system. The ambient temperature
should never drop below 5 ° C, otherwise the device can be permanently damaged. It is not
advisable to install the devices in rooms with high humidity. The location should be large
enough to ensure free access to the device because regular refilling of the salt is required.
7. Installation of Bypass
The device is equipped with a valve that allows you to bypass the system if necessary, to pass
on unfiltered water.
• Close the water inlet.
• Remove the safety bar from the slide.
• Pull the screw connection out of the bypass and mount it on the control sec-
tion of the water softener using the seals provided.
• There is a turbine at the outlet that can measure the water flow. Before as-
sembly, check whether the turbine is rotating freely. Check this by blowing
hard into the drain. Push the water softener bypass onto the screw connec-
tion (control head).
• Insert the safety bar.
• Insert the plug to connect the water meter - drawing (A).

www.bestwater.de 9
Drawing. A. Installation of Bypass
8. Installation of the device
The device must be connected with a flexible hose (not supplied) for installation. A mechani-
cal coarse particle filter (min. 50 microns) should be installed in front of the water softener to
protect it from contamination. If the device is to be operated with the additional bypass valve,
it must first be connected to the device and then to the hoses. You can also bypass the usual
valves as shown in the illustration (C).
Look for the flow direction arrows on the control head on the water inlet and outlet connec-
tion. The turbine should be at the outlet of the device. Before assembly, check that the tur-
bine is rotating freely. To assemble the device, you must use the existing installation materi-
als. If you have any problems or questions, contact a qualified company or authorized service
company.

The regeneration water drainage from the control head can be connected to the sewage sys-
tem using a flexible ½ “hose.
The overflow mounted on the device housing should also be connected to the sewer drain
with a ½ “flexible hose.
The sewage connections must be installed below the level of the salt pool in the storage con-
tainer so that the overflowing water can drain off without pressure.
After connecting the softener, the storage container should be filled with regeneration salt
tabs. The regeneration salt level should always be higher than the water level in the storage
container. If necessary, the regeneration salt should be refilled so that the salt pool is availa-
ble in sufficient quantity for the upcoming regeneration processes. Table 2 shows the average
regeneration salt consumption.
Attention: Please only use regeneration salt in tabs form.

Drawing C. An example of a recommended assembly scheme
The following requirements should be observed for assembly and use:
• All parameters such as water hardness, time, etc. are already set on delivery.
If you do not supply the system with power for a longer period of time (ap-
prox. 30 days), the values must be reset.
• The menu language is German, another language can be set before delivery
• The water hardness is automatically determined by the system and "sof-
tened" according to your specifications
• Special knowledge or execution by a specialist is advisable during installation
It is absolutely necessary to use a drinking water filter, if possible, with a pres-
sure reducer, with at least 50-micron filter
• All connections must be made in accordance with the applicable guidelines
and standards.
• The subsurface must be level and able to bear the weight of the filled water
system
Connections must be made according to local conditions
• The connection to the existing installation must be made using flexible hoses
Control valve control head may only be connected to the existing water sys-
tem with flexible hoses.
• Flexible hose included should be connected to the drain. The line should not
be longer than 6 m.
• In the case of threaded connections without an additional seal, a suitable
sealant e.g. Use PTFE Teflon tape.
• Only open the main water connection when all work has been properly car-
ried out

Water checks (e.g. with litmus paper) should be carried out at regular inter-
vals. This guarantees the correct operation of the device.
• Please use only salt tablets suitable for the device for water softening (purity
should be 99.5%). Others, such as finely ground salt, are not permitted.
• The device is only to be installed for indoor use, in the temperature range of 5
- 45 ° C, with no excessive air humidity.
• If the water line pressure is greater than 6 bar, a pressure reducing valve must
be connected upstream.
• Only original parts may be connected to the control valve.
• Please protect from children

11. first time of Usage
11.1. Vent the installation
For safety reasons, it is necessary to bleed the entire system before the first start-up. First,
the water supply to the water treatment system must be stopped or the slide switch of the
bypass set to "closed". Then the valve on the water softener for sampling must be open and
the water inlet can be opened slowly, step by step, to let water run into the system. The air
escapes audibly through the inflowing water through the open valve on the water purifier.

www.bestwater.de 16
The valve can only be closed again when no air escapes from the valve but a steady stream of
water. The water should run in slowly and a pause should be taken when taking in the water if
necessary.
The installation is now vented.
CAUTION! Water and salt must be filled in before the first start-up. After that, you should
wait 30 minutes to dissolve the salt in the water. A first regeneration must then be carried
out.
11.2. First Regeneration
you can start the Regeneration with the button for manual setting .
The Regeneration runs automatically and after the first regeneration the system is ready for
operation
12. Operation of the water softener
12.1. Checking the salt inventory and filling up the salt
The salt level in the container should be checked regularly (preferably once a week) to avoid a
lack of salt. Table 2 shows the average amount of salt consumed per regeneration. Salt must
then be refilled if necessary. It must be ensured that the salt stock is higher than the water
level (water surface must not be visible). Salt may only be used in tablet form.
CAUTION! Dissolved salt can cause irritation in contact with eyes and skin. In case of contact,
rinse quickly with plenty of clear water.
salt replenishment

www.bestwater.de 17
12.2. Avoiding salt deposits
High humidity or the wrong type of salt can lead to salt deposits and lumps in the salt con-
tainer. This can slow down the solution process and less brine can be provided, which reduces
functional performance. The water hardness will then not develop as desired. If you suspect
salt deposits and clumping, it is recommended to pour warm water into the brine container
and to remove the deposit by tapping the container lightly. If normal humidity levels exist at
the location, please check the quality of the salt used.
Drawing. Salt deposits
12.3. Cleaning the injector
In the event of contamination by sand, small stones and other dirt, the injector, which is re-
sponsible for the introduction of the brine, can be blocked. If a sediment filter (drawing F) is
installed in front of the water treatment system and the salt is of sufficient quality, the injec-
tor should not become blocked. If this is the case, the injector must be cleaned.
The design of the injector is described in drawing F. The main parts responsible, in case of
constipation, are marked with 3 and 2. To carry out the removal and cleaning, you must first
stop the water supply. Then the cold-water inflow must be unscrewed. The fastening screw
must be loosened using a screwdriver (marked with 1). Then the injector can be detached
from the control section. Pay attention to the integrity of the seals. Parts 12 and 14 must be
loosened with a screwdriver. All parts should be rinsed under clear, warm water and then
blown through. Then all parts are reassembled in reverse order.

12.4. Regeneration started manually
Manual regeneration is recommended if:
• a particularly large amount of water was required in a short period of time
• Salt has been added to the brine tank (if no salt has been added for a long time)
For the start of the regeneration press .
13. System operating cycles
NORMAL OPERATION - the system is in the 1st cycle - water softening
BACKWASH - the system is in the 2nd cycle - the water runs through the valve and the cen-
tral pipe backwards through the brine tank and is then discharged through the drain into the
sewage system.
REGENERATION - the system is in the 3rd cycle - regeneration with salt and slow rinsing. The
container slowly fills with fresh water. As soon as the container is completely filled, the con-
tents together with the “used” brine are drained into the sewage system. Then the container
is rinsed again with fresh water to ensure that all salt residues are removed. Also, in this cy-
cle, no water is released into the house installation to protect it from contamination.
SALT REFILL - the system is in the 4th cycle - water is fed into the salt container to dissolve
new salt in the water and prepare new brine for regeneration. The salt stock is adjusted with
the help of refill time. The longer the refill takes, the more salt can be dissolved.
QUICK WASH - the system is in the 5th cycle - the brine bed (grounds container) is rinsed
again and discharged through the main pipe into the sewage system.

www.bestwater.de 19
After the quick wash is completed (the 5th cycle), the system automatically returns to normal
operation.
