Product Overview & Area of Application
The Aqmos R2D2-72 Black Edition water softening system is a compact softener in a cabinet housing designed for households and smaller residential units with increased water demand. It reduces water hardness in the drinking water area, thereby helping to protect pipes, fittings, household appliances, and water heaters from limescale deposits.
With a capacity of 7,200 liters at 10 °dH and a salt tank volume of 50 kg, the R2D2-72 is designed for applications with regular water consumption. The Black Edition combines the R2D2-72 system with a connection set and mounting block for clean integration into the household water installation.
Technology & Equipment
The Aqmos R2D2-72 operates with a volume-controlled BNT 1650 control valve. Regeneration occurs based on consumption, adapting salt and water usage to actual operation. The system uses ion exchange resin to reduce water hardness and is built in a compact cabinet housing with an integrated salt tank.
The BNT 1650 control valve is pre-installed and operated via microprocessor-controlled electronics. Operation requires a 230 V power connection, a suitable water connection, and a drain connection for regeneration water.
Everyday Benefits
Softer water can reduce limescale deposits on fittings, shower surfaces, household appliances, and water-carrying components. Especially in households with multiple people, the larger R2D2-72 version ensures longer usage intervals between regenerations.
The integrated salt tank with a volume of 50 kg reduces refilling effort during operation. Thanks to volume-controlled regeneration, the system is not operated rigidly by time but depending on actual water consumption.
System Integration & Compatibility
The system is typically integrated into the household water line after the water meter, water filter, and, if applicable, pressure reducer. The included mounting block supports separation from the household water network, a bypass function, and the adjustment of residual water hardness.
For proper installation, a frost-free and dry location, a power connection in the immediate vicinity, and a drain connection for the regeneration water are required. A suitable protective filter upstream of the system is recommended to protect the softening system from contamination.

Installation
Installation is carried out in the household water network after the water meter, water filter and, if applicable, pressure reducer. Before commissioning, the water inlet, wastewater hose, overflow protection hose and power connection must be established in accordance with the installation and operating instructions.
Work on the water installation should be carried out by qualified personnel. For safe operation, the flow direction at the mounting block, sufficient water pressure and a suitable drain for regeneration water must be observed.
Notes
The system is intended for operation in the drinking water sector to reduce water hardness. The installation location must be frost-free, dry and protected from moisture.
Regeneration salt 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 to suit the installation.
