Product Overview & Area of Application
The AQMOS R2D2-32 water softening system with backwash filter, connection set, and mounting block is a compact complete system for reducing water hardness in the drinking water sector. It is particularly suitable for households with limited space and up to four people where limescale deposits in pipes, fittings, and connected appliances are to be reduced.
The system combines softening, pre-filtration, pressure regulation, and easy installation via the connection set and mounting block. As a result, the system is designed not only as a standalone water softener but as a coordinated solution for the household water connection.
Technology & Equipment
The R2D2-32 operates with a volume-controlled BNT 1650 control valve in a compact cabinet housing. Softening is achieved through ion exchange resin, which reduces calcium and magnesium ions and thus lowers water hardness. Regeneration is triggered by microprocessor control and is based on actual water consumption.
The included backwash filter with integrated pressure reducer and pressure gauge serves for pre-filtration and pressure regulation before the softening system. The mounting block adds a bypass function, blending valve, and sampling tap for setting and monitoring residual hardness.
Everyday Benefits
During operation, the system works largely automatically in the background. The R2D2-32 is designed for consumption-dependent regeneration and essentially requires regular checking of the salt supply. Thanks to the compact cabinet housing, the system can be easily accommodated even in smaller utility rooms or house connection areas.
The complete system facilitates clean integration into the household water installation because the backwash filter, connection set, and mounting block are already matched to the operation of a softening system.
System Integration & Compatibility
The system is integrated into the house water line behind the water meter or in the designated installation section. The mounting block allows the system to be separated from the house water network and enables bypass operation when untreated water is needed or maintenance work is pending.
Operation requires a frost-free, dry installation location, a power connection in the immediate vicinity, and a drain connection for the regeneration water. The residual hardness is set via the blending valve on the mounting block or on the control valve.

Installation
Installation is carried out in the house water line by qualified personnel. Before commissioning, the flow direction, the connections on the control head, the drain hose, the overflow hose and the mains connection must be checked in accordance with the installation and operating instructions.
The mounting block is integrated into the installation line and allows the residual water hardness to be set as well as bypass operation. The backwash filter is installed upstream of the water softening system and helps protect the system from suspended particles in the tap water.
Notes
The system is intended for operation in the drinking water sector to reduce water hardness. The installation location must be dry, frost-free, and protected from moisture. Regeneration salt according to DIN 19604 or DIN EN 973 Type A must be used for operation.
The local water hardness must be checked during commissioning and taken into account in the system programming. For permanently very soft water, the residual hardness should be set professionally so that the system is operated in line with the house installation.
