INSTALLATION REQUIREMENTS INSTALLATION Key to Symbols Isolating valve Mixing Valve Overflow Indicator Pressure Reducing Valve Twin Impeller Pump Tempering Valve Mini Expansion Vessel Gravity Fed System - The mixer MUST be fed from a cold water cistern and hot water cylinder providing nominally equal pressure. - Page 11 Gas Heated System - The mixer MUST be installed with a gas water heater or combination boiler of a fully modulating design. A fully modulating boiler is one where the draw off rate is indirectly controlling the gas flow to the boiler, producing a relatively constant hot water temperature.
- Page 12 Mains Pressurised Instantaneous Hot Water System - The mixer installed with systems of this type is supplied hot water via a tempering valve, this provides relatively constant hot water and the shower will compensate for temperature changes should they occur. Pumped System - The mixer can be installed with an inlet pump (twin impeller).
