8 Bar Pressure Relief Valve; Valve Set Can Be Grouped Two Ways - MEGAFLO Eco Product Manual

8 Bar Pressure Relief Valve (see Figure 5 below)
This should be installed between the 3 bar Pressure Reducing Valve and the MEGAFLO Eco cylinder. Should a balanced pressure cold water draw off supply be
required for the cold water outlets, this should be taken off between the 3 bar Pressure Reducing Valve and 8 bar Pressure Relief Valve (see Figure
7, p. 14). Branches to drinking water outlets should be taken BEFORE the 8 bar Pressure Relief Valve to avoid the possibility of warm
expanded water being drawn from the tap.
