This should be installed between the 3 bar Pressure Reducing Valve and the MEGAFLO Eco Solar cylinder. S hould 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 Pressure Relief Valve to avoid the possibility of warm expanded water being
drawn from the tap.
