Product Overview & Area of Application
The AQMOS R2D2-72 Black Edition water softening system is a compact softening unit in a cabinet-style housing for households with typical use by 2 to 7 people. It reduces the water hardness in the drinking water area and thereby helps to reduce limescale deposits on fittings, pipes, household appliances, and water heaters.
As the largest version of the R2D2 series, the unit is suitable for larger households, single-family homes with increased water demand, or smaller residential units. The Black Edition is the dark version of the R2D2-72 and is offered as a single softener without connection accessories.
Technology & Equipment
The AQMOS R2D2-72 Black Edition operates with ion exchange resin. The calcium and magnesium ions responsible for limescale are reduced, so that the water is routed into the house installation with a lower hardness after the unit.
The volume-controlled BNT 1650 control valve records the actual water consumption and controls the regeneration automatically. The unit is microprocessor-controlled and designed for a demand-based salt and water consumption with each regeneration.
Everyday Benefits
Softer water can reduce the cleaning effort on fittings, shower surfaces, and household appliances. At the same time, softening supports a lower-limescale operation of water-bearing appliances such as washing machines, dishwashers, kettles, or water heating.
Thanks to automatic regeneration, the unit operates largely independently in normal operation. For the operator, the focus is primarily on regularly checking the salt supply and setting the residual hardness appropriately.
System Integration & Compatibility
The R2D2-72 Black Edition is integrated into the cold water line of the household water installation. It is typically installed after the water meter, water filter, and, if applicable, pressure reducer, so that the unit is protected from contamination and operated within the permissible pressure range.
For installation, a frost-free and dry location, a power connection in the immediate vicinity, and a drain connection for regeneration water are required. Connection set, mounting block, backwash filter, and regeneration salt must be considered separately depending on the existing installation.

Installation
Installation is carried out in the house water supply system after the water meter, water filter and, if applicable, pressure reducer. Connection should be performed by qualified personnel to ensure that flow direction, pressure range, tightness, wastewater routing and electrical supply are correctly checked.
The wastewater and overflow hoses must be routed separately and with backflow protection to the sewer connection. The installation site must be dry, frost-free, level and protected from moisture.
Notes
The unit is intended exclusively for the drinking water sector and for reducing water hardness. For operation, regeneration salt tablets made of high-purity vacuum salt according to DIN 19604 or DIN EN 973 Type A must be used.
The residual hardness should be set during commissioning to suit the local water quality. For drinking water installations, complete softening to 0 °dH is not recommended; the water hardness should be adjusted via blending.
