Purpose of Use: The softliQ:SD21 is exclusively designed for the softening/partial softening of cold drinking water. It protects pipes and equipment from salt deposits and related malfunctions.

Operation Method:

• Uses ion exchange method
• Capacity adjusts automatically based on the last 4 weeks' usage
• Regeneration occurs when at least 50% of capacity has been consumed
• Regeneration time is automatically scheduled outside of usage hours (or manually adjustable)
• During regeneration, unsoftened water is supplied
• Cost-efficient salt and energy consumption
• Mandatory full regeneration every 4 days for hygiene reasons

Smart Operation with App: Using the Grünbeck myProduct-App, you can remotely control, register the device, and receive notifications.

Operational Settings:

• Eco: Minimum resource consumption
• Comfort (factory setting): Optimal balance of resources and performance
• Power: Maximum performance for high demands
• Individual: User profile-based setting
• Fix: Fixed capacity setting without self-adaptation

Construction & Maintenance:

• Compact design for space savings
• Ergonomic and user-friendly design
• Removable salt tank for easy cleaning
• Built-in filling aid
• Easy access to maintenance cover
• Safety float for protection during power outage
• Special resin for drinking water
• Glass beads for uniform water distribution

Installation Conditions:

• SoftliQ devices are certified by DVGW (no additional system separator required)
• Installation area must be frost-resistant and protected from chemicals, vapors, paints
• If the softened water is intended for drinking, the temperature must not exceed 25°C
• Water filter and possibly pressure reducer are required before the unit
