Product Overview & Area of Application
The AQMOS R2D2-32 Black Edition water softening system is a compact water softener in a cabinet housing for smaller households with typical use by 1 to 4 people. It reduces water hardness in the drinking water area and thus helps to reduce limescale deposits on fittings, pipes, household appliances, and water heaters.
The Black Edition is the dark version of the R2D2-32 and is particularly suitable for apartments, single-family homes, row houses, or smaller utility rooms where space-saving central water softening is desired.
Technology & Equipment
The AQMOS R2D2-32 Black Edition works with ion exchange resin. This reduces the calcium and magnesium ions responsible for limescale, so that the water is routed into the house installation with a lower hardness after the system.
The volume-controlled BNT 1650 control valve records the actual water consumption and controls the regeneration automatically. The system is factory-prepared for operation; during commissioning, the time, water hardness, and capacity are set according to the local situation.
Everyday Benefits
Softer water can reduce the cleaning effort on fittings, shower surfaces, and household appliances. At the same time, the system supports a lower-limescale operation of water-bearing appliances such as washing machines, dishwashers, or kettles.
Thanks to automatic regeneration, the system operates largely independently during normal operation. For the operator, the focus is primarily on regular checking of the salt supply and the appropriate setting of the residual hardness.
System Integration & Compatibility
The R2D2-32 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 system 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 accessories, mounting block, backwash filter, and regeneration salt must be considered separately depending on the existing installation.

Installation
Installation is carried out in the household water supply system downstream of the water meter, water filter and, if applicable, pressure reducer. Connection should be performed by qualified personnel so 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 system is intended exclusively for the drinking water sector and for reducing water hardness. For operation, regeneration salt tablets made of high-purity vacuum salt in accordance with DIN 19604 or DIN EN 973 Type A must be used.
The residual hardness should be set at 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.
