The water softener softliQ:SD21 (application recommendation: 1 to 9 people) softens water according to the water consumption. The system capacity is automatically adapted to the individual water consumption of the user. A continuous supply of soft water is always guaranteed as the softener regenerates once a day at a time when no water is needed. The softliQ:SD21 system operates according to the ion exchange principle and features a fully automatic control unit as well as a wear-optimised control valve. Based on the set raw water hardness and the water withdrawals, the water softener adapts to the conditions prevailing on site. Technical intelligence ensures efficient softening with the lowest consumption of salt and power possible. The Comfort Mode is set by the factory. In case of significant fluctuations in the water consumption, however, it is possible to switch to the Power Mode. The system is operated via the integrated colour touch display or via Grünbeck's myProduct app.
The green LED ring communicates various operating states of your system and draws your attention to messages. The inernal infrared light sensor monitors the system’s salt level and alerts you in good time about a lack of salt.
Observe local installation directives, general guidelines and technical specifications. The installation site must be frost-proof and ensure the system's protection from chemicals, dyes, solvents and vapours. Always install a drinking water filter and, if required, a pressure reducer (e.g. pureliQ:KD) upstream of the systems. For the electrical connection, a shock-proof socket is required within a range of up to approx. 1.2 m of the system.
A drain connection must be provided to discharge the regeneration water. In case the flushing water is directed to a lifting system, make sure that said device is salt water proof. The installation room must have a floor drain. If this is not the case, an appropriate safety system (e.g. protectliQ) has to be installed. A cold water withdrawal point must be available downstream of the system and in close proximity to it. If the softened water is intended for human consumption as defined by the German Drinking Water Ordinance, the ambient temperature must not rise above 25 °C. In case of applications that are purely technical, the ambient temperature must not exceed 40 °C.
