3. Gravity Fed Showers
Caution! Risk of product damage. Do not fit the Mira Digital Mixer - HIGH
PRESSURE/COMBI VALVE with Gravity Fed Systems.
Cistern
Minimum 230 litres
The shower control must be fed from a cold water storage cistern and a hot water
cylinder providing nominally equal pressures. Pipework layouts and connections
must be such that other draw-offs will not effect water supplies to the shower, shared
supplies may lead to airlocking or water starvation. It is therefore best practice to have
independent hot and cold supplies to the Low Pressure (pumped) Digital Mixer Valve.
