APPLICATION

The heating circuit refill unit is suitable for use in heating circuits up to a maxi-
mum water temperature of 90 °C.
According to DIN EN 1717, only permanent connections are permitted for filling heating systems with
drinking water.
The heating circuit refill unit automates the filling of hot water heating systems. The integrated pipe dis-
connector (type BA system separator) compliant with DIN EN 1717 and DIN EN 12729 prevents pressur-
ing back of heating water into the drinking water pipe. In this combination with the pipe disconnector, the
direct permanent connection to the heating system is permitted in accordance with DIN EN 1717. The in-
tegrated pressure reducer ensures the correct and constant filling pressure of the system.
