NOTICE
Observe recommendations for maintaining drinking water hy-
giene in accordance with VDI/DVGW 6023 Sheet 1!
• Ensure a water temperature of ≤ 20 °C to max. 25 °C.
• Exchange all the water at least every 72 hours.
Wilo-SiFresh is a potable water cold-circulation (Trinkkaltwasser-Zirkulation) system with
integrated circulator and water exchange device. Circulation serves to even out temper-
ature peaks within the drinking water installation and to flow through the pipe strands to
avoid stagnation. The system performs continuous monitoring of the operating parameters
and the water temperature.
The solenoid valve (see Item 9) triggers manually or automatically via temperature or time
control: temperature control to maintain a temperature reduction in the drinking water in-
stallation and time control in order to maintain the intended operation.
