2. 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 exchanger,
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 process,
the appliance regains its ion exchange capacity and can treat water again. This revitalisation
process allows you to use the water treatment system for a long time.

4. 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 technology, which is
dependent on the relative position to one
another, which generate successive 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 revitalisation
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 overflow 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.

5. Preparation for the installation
After unpacking the unit, remove the power supply and the bypass valve from the brine tank. When
lifting and moving the device, use only the provided recesses in the housing. Do not lift the appliance
when it is connected to power or water pipes, as these may then be damaged or torn off. The
appliance should be placed as close as possible to the mains water supply pipe of the building (at the
water meter for a public water supply) or hydrophore (with own water supply) and near access to
the sewage system. In addition, a constant power supply is required to operate the device. Make
sure the floor is stable and can support the weight of the water-filled appliance. The selected
location should be chosen so that there is free access for the maintenance of the appliance.
6. Technical data for the water softener appliance
The specifications of the water treatment system depend on its size. Because of the small size of the
ion exchanger, the system should only be used if water does not receive more than 1ppm of iron and
manganese.

7. Water supply connection
ONLY BY AUTHORIZED PERSONS
The appliance should be connected to the existing water supply with flexible hoses (not included).
A mechanical filter (at least 50 microns) must be installed. This pre-filter is installed to protect
against contamination of the water installation supply and sanitary facilities, such as: rust, sand
particles, mud, fibres, etc. It is recommended to install a mechanical filter in front of the water
treatment appliance as this will extend its life and ensure a properly functioning appliance.
Locate the water inlet and outlet on the control head (marked with arrows pointing into or out of the
device). At the output of the device (in the bypass) is a turbine. Make sure that the turbine is free
and rotatable before installation. Use only the specified water installation materials when mounting
the unit.
7.1 Connecting the appliance to the wastewater outlet
The flexible wastewater hose must be connected to the wastewater drain and secured with a ½ inch
hose clamp. The hose should be positioned below the device head and not be bent at any point.
Secure the hose so that it cannot flood the room.
7.2 Connect the brine drain to the wastewater
If the brine inlet and tank filling system is not working properly, the tank may overfill. In this case, the
overflow pipe serves as drain for the excess brine. In order to avoid flooding the room in the event of
a malfunction, the overflow pipe should be connected to the wastewater drain with a flexible hose.

8. Operating mode
During operation, the name of the current operating mode is shown on the display.
During revitalisation, the time remaining until the end of the mode is visible. During the
revitalisation, it is possible that fresh water is supplied.
The display shows the following information:
1. the amount of water remaining for revitalisation
2. Current water flow rate
3. Current operating mode
During operation
The appliance is in water treatment mode.
Raw water flows through the tank and filter and is routed
through the distribution line up to the controller and from
there into the house installation system.
Backwash
The unit is in backwash mode. Fresh water flows through the
controller to the tank with the ion exchanger and is
discharged into the wastewater system. The water rinses the
tank and dissolves incrustations.
Refilling the brine and slowly
rinsing
Water flows through the control head and causes the
brine to be drawn in, which cleans the ion exchanger. Water
is then drained into the wastewater during revitalisation.
After all the brine has been drawn in, the ion exchange bed
is slowly rinsed with water.
Quick Rinse
Provides a quick rinse of the brine residues on the ion
exchanger. This improves the correct functioning of the
ion exchanger. The water is drawn in from above and
directed through the ion exchange resin and then
discharged through the central tube.

www.bestwater.de 10
9. RX Control unit
The RX control unit is equipped with a microcomputer, with which the operating parameters of
the water treatment system can be adapted to the physical-chemical parameters of the water.
The 79BD and 82BD controllers have two types of menus: open and closed.
To access an open menu, you must unlock the device by simultaneously pressing the "up-down"
buttons.
In open menus you can edit the basic parameters, i.e. set the time and the water hardness, as
well as determine the revitalisation time.
Switching between the parameters and changing the values is done by pressing the "up-down"
buttons. The parameter selection and the confirmation of the changes are confirmed with
"Enter".

www.bestwater.de 11
NOTE!! You must have the necessary knowledge to access the closed menu. Changing the
operating parameters without proper knowledge may result in the unit consuming more water
or salt, or the revitalisation process not working properly, or otherwise impairing the
operation of the appliance.
10. Description of the control buttons
During water treatment, the screen shows the following:
In Operation - During revitalisation: The current operating mode number (see description
below) and the current amount of water that the unit can process without revitalisation being
required.
A-Menu / confirm; B- Force revitalisation / Back; C-down; D-up

www.bestwater.de 12
11. Fill level control and salt refilling
11.1. Initial start-up
Before using the unit for the first time, pour salt into the salt container and fill with water. Wait
about 30 minutes for enough salt to dissolve in the water. Then perform a revitalisation process.
11.2. Checking the Fill level and refilling with salt
You should check the amount of salt in the tank regularly (recommendation: at least once a week) to
make sure there is enough salt. The table (see page 7) shows the average salt consumption for the
revitalisation process. It should always be refilled with as much salt so that no more water is visible.
Use only salt in tablet form intended for water treatment systems.
DANGER! Saltwater (brine) can cause eye, skin and wound irritation. Avoid contact with the inside of
the brine tank. In case of contact with the saline solution, rinse with sufficient running water.
11.3. Prevention of clumping
High humidity or incorrect salt can lead to the formation of large salt deposits in the tank.
These deposits can interfere with the proper revitalisation of the ion exchanger. As a result,
the water is not properly processed.
If you suspect that salt deposits have formed, you can beat gently against the sides of the salt
container (only with flat hands, never with tools). If this does not help, you can dissolve the
deposits with warm water. Persistent clots can be broken open with a long screwdriver
(CAUTION). If the clumps are due to poor salt, rinse the tank completely. Then fill the tank
with salt, which is suitable for this type of water treatment system.
