The pump in this product is not suitable for dry running. It is essential you follow the commissioning sequence detail in this guide.
  • Page 15 *Note: Maintained (or dynamic) pressure is the pressure at the valve inlets during operation. Some installations will see a significant pressure drop in the supply pipework when water is flowing, especially when long plastic pipework and small bore fittings are used. It is recommended to keep supply pipework as short as possible, avoid unnecessary bends and minimise the number of fittings that are used. For longer pipe runs, it may be necessary to increase the nominal pipe size to reduce the pressure drop. Consult a plumbing professional if you are unsure.

  • Page 16: Suitable Plumbing Installations

    Suitable Plumbing Installations Digital Mixing Valve (High Pressure/Combi Models) 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.
  • Page 17 Digital Mixing Valve (Pumped/Gravity Models) 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.

    Alternatively reduce the outlet flow by decreasing the flow rate with the user controller. *Note: If your water system is not capable of delivering minimum maintained pressure at the valve inlets, you will not be able to achieve the maximum flow rate from your shower even if adjusted via the Mira Showers app. Ensure you have the minimum required maintained pressure at the valve inlets before installation.
