Product Overview & Area of Application
The Aqmos water softening system R2D2-32 is a compact softening system in a cabinet housing designed to reduce water hardness in the drinking water sector. It is designed for smaller households with 1 to 4 people and is particularly suitable where limescale deposits on fittings, pipes, water heaters, and household appliances should be reduced.
The version with connection set and mounting block is designed for orderly integration into the household water installation. It is used in the household water network after the water meter, water filter, and, if applicable, pressure reducer.
Technology & Equipment
The R2D2-32 operates with a volume-controlled BNT 1650 control valve. The valve controls regeneration as needed based on water consumption, thus supporting economical use of salt and water. The softening resin reduces water hardness according to the ion exchange principle, in which calcium and magnesium ions are exchanged for sodium ions.
The compact cabinet housing combines the softening unit and salt tank in a space-saving design. The system is intended for operation with regeneration salt tablets and is set via an LCD display on the control valve.
Everyday Benefits
Softer water can reduce limescale residues on fittings, shower surfaces, and household appliances and reduce daily maintenance effort. The volume-controlled regeneration works automatically in the background, so that after proper setup, the system can be operated without constant manual operation.
Thanks to the cabinet housing, the system remains compact and clear. The salt supply is stored directly in the housing and can be refilled as needed.
System Integration & Compatibility
The water softening system is integrated into the building's cold water line. For operation, a frost-free and dry installation location, a power connection in the immediate vicinity, and a drain connection for the regeneration water are required.
The mounting block supports the separation of the system from the house water network, the bypass function, and the adjustment of the residual water hardness. After commissioning, the water hardness should be checked at the sample tap and adjusted to suit the installation.

Installation
Installation is carried out in the house water line after the water meter, water filter, and, if applicable, pressure reducer. A protective filter should be installed upstream of the system to reduce dirt and sludge. The mounting block must be installed according to the flow direction and enables bypass operation, sample extraction, and residual hardness adjustment.
For installation, a suitable drain connection for regeneration water, a power connection in the immediate vicinity, and a frost-free, dry installation location are required. Work on the drinking water installation should be carried out by qualified installation personnel.
Notes
The system is intended for the drinking water sector to reduce water hardness. The local raw water hardness must be taken into account during commissioning and set appropriately on the control valve. Suitable regeneration salt tablets according to DIN 19604 or DIN EN 973 Type A must be used for operation.
The residual water hardness should be checked after commissioning and adjusted via the blending. Fully softened water is not intended as a target value for permanent operation in the household network; a suitable blending of softened water with raw water is recommended.
