INSTALLATION REQUIREMENTS Key to Symbols Isolating Valve Mixing Valve Overflow Pressure Reducing Valve Twin Impeller Pump Single Impeller Pump Tempering Valve Mini Expanssion Vessel Gravity Fed Shower - The shower MUST be fed from a cold water cistern and hot water cylinder providing nominally equal pressure.
Page 11
Gas Heated Shower - The shower MUST be installed with a gas water heater or combination boiler of a fully modulating design. A modulating boiler is one that the draw off rate is indirectly controlling the gas flow to the boiler, producing a relatively constant hot water temperature (only suitable for products with 6”...

Mains Pressurised Instantaneous Hot Water Shower - The shower 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 Shower - The shower can be installed with an inlet pump (twin impeller).
INSTALLATION General Installation must be carried out in accordance with these instructions, and must be conducted by designated, qualified and competent personnel. Before commencing, ensure that the installation conditions comply with the information given in SPECIFICATION. For Type 3 valves see also Installation conditions in TYPE 3 VALVES.

Divertor Elbow Outlet Connector For installations where the force of the spray from the handset is excessive or where water conservancy is an issue, the 10 litre/minute flow regulator supplied should be fitted to the outlet connector (divertor elbow). Direction of Divertor Elbow Water Flow Unscrew the outlet connector.
Tepid Pre-set Maximum The Mira Montpellier is fitted with a flow divertor which controls the flow of water to either the fixed shower head or the flexible shower fitting. It is not designed for both shower options to be used at the same time.
