Page 13: Suitable Plumbing Installations
Suitable Plumbing Installations Digital Mixing Valve (High Pressure/Combi) 1. Combination boiler systems - the digital high pressure/combi shower can be installed with an instantaneous combination boiler. 2. Unvented mains pressurised system - the digital high pressure/combi shower can be installed with an unvented, stored hot water cylinder system. 3. - Page 14 Digital Mixing Valve (Pumped/Gravity) 1. Gravity fed hot water systems Caution! Digital pumped/gravity valves must never be plumbed to mains pressure systems. This includes mixed gravity fed and mains pressure e.g. gravity hot and mains cold. Doing so will invalidate the warranty and potentially cause product and property damage.

Page 15: Showering Maximum Flow Rate
It is therefore possible this mixing valve will need to have its outlet flow rate altered to match the capability of the water system. This digital mixing valve has been factory pre-set to 16 l/min outlet flow rate but can be altered by use of the Mira Showers app. High flow rate demanded from low kW combination boilers will result in poor blend temperature stability and could result in your shower going cold. We strongly recommend you to alter the outlet flow rate as the table below. -
