3. Gravity Fed Showers

Caution! Risk of product damage. Do not fit the Mira Digital Mixer - HIGH

PRESSURE / COMBI VALVE with Gravity Fed Systems.

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.
