Product Overview & Areas of Application
The R2D2-48 water softening system is a compact complete system for reducing water hardness in the household water supply. The version with backwash filter, connection set and mounting block combines scale protection, pre-filtration and easy-to-access integration into the installation.
With a capacity of 4,800 liters at 10 °dH, the R2D2-48 is designed for households with typical water consumption in the range of 2 to 5 people. The cabinet housing remains comparatively space-saving at 220 mm wide and 825 mm high, making it well suited for utility rooms, laundry rooms or comparable installation areas.
Technology & Equipment
The system operates with the BNT 1650 control valve and volume-controlled regeneration. This means: regeneration is based on actual water consumption and not just on a fixed time interval. This allows operation to be better adapted to the real needs of the household.
The backwash filter handles the pre-filtration of particles such as rust, sand and sediment. In combination with the mounting block, the system can be integrated cleanly into the household water supply, separated via the bypass if necessary, and monitored via the sampling tap.
Everyday Benefits
The R2D2-48 reduces limescale-related deposits in the tap water and thereby supports lower-scale operation of downstream appliances. Operation remains clear, as the control valve automatically manages regeneration and ongoing operation essentially requires regular checks and refilling of regeneration salt.
The cabinet housing accommodates the softening technology and salt tank in a closed design. The maximum salt capacity of 40 kg allows longer refill intervals, depending on water hardness and consumption.
System Integration & Compatibility
The system is integrated into the household water network after the water meter, water filter or pressure reducer, and before the points of use. Connection is made via 1-inch female thread. Operation requires a frost-free, dry installation location, a 230 V power connection, and a drain connection for regeneration water.
The desired residual water hardness can be set via the blending valve. Water hardness should be checked at a suitable tap near the system so that the setting can be verified in a traceable manner.

Installation
Installation is carried out in the house water supply network after the water meter and before the points of use. The mounting block must be installed according to the direction of flow. Before working on the water installation, the main water supply is shut off and the line pressure is released.
For commissioning, a suitable drain connection for regeneration water, a power supply in the immediate vicinity, and a dry, frost-free installation location are required. Installation and connection to the drinking water installation should be carried out by qualified personnel.
Notes
The system is intended for operation in the drinking water sector to reduce water hardness. For proper operation, suitable regeneration salt according to DIN EN 973 Type A must be used.
The local raw water hardness should be checked during commissioning and taken into account at the control valve or via the blending. A residual hardness in the range of 6 to 8 °dH is described in the instructions as a sensible setting.
