INTRODUCTIONThank you for purchasing a quality Mira product. To enjoy the full potential of yournew product, please take time to read this guide thoroughly, having done so, keepit handy for future reference.The Mira Excel is a Thermostatic Mixer with independent selection of spray forceand temperature. The Thermostatic Mixer incorporates a wax capsule temperaturesensing unit. This provides an almost immediate response to changes in pressuresor temperature of the incoming water supplies to maintain the selected temperature.An adjustable maximum temperature stop is provided which limits the temperature tothe desired level. An override button allows the user to exceed the preset maximumtemperature. The flow control utilizes ceramic plate technology operating directly onthe hot and cold inlets to provide precise control and isolation of the incoming watersupplies. Inlet filters are fitted to protect the thermostatic control mechanism.The Mira Excel (Exposed Version) has adjustable inlets to fit pipework centresbetween 150 mm and 155 mm.Mira Excel: An exposed shower control for connection to wall mounted or rear entrypipework.Mira Excel B: A built-in shower control for connection to concealed pipework.Patents and Design RegistrationDesign Registration:3 003 921, 3 003 922Patents:GBFranceGermany2 291 6930 694 721(E)695 13 455.8GuaranteeFor domestic installations, Mira Showers guarantee the Mira Excel against anydefect in materials or workmanship for a period of 5 years from the date of purchase(shower fittings for one year).For non-domestic installations, Mira Showers guarantee the Mira Excel againstany defect in materials or workmanship for a period of one year from the date ofpurchase.For terms and conditions refer to the back cover of this guide.If you experience any difficulty with the installation or operation of your newThermostatic Mixer, please refer to ‘Fault Diagnosis’, before contacting Kohler MiraLtd.

SPECIFICATIONS1. Pressure Ranges1.1. Minimum maintained pressure: 0.1 Bar (1.0 metre head) when used with Mirashower fittings.1.2. Maximum maintained pressure: 5.0 Bar.1.3. Maximum static pressure: 10 Bar.Note: Nominally equal inlet supply pressures are recommended for optimumperformance.2. Temperature Control2.1. Close temperature control is provided between 35 C and 45 C.Note: The temperature control specification, outlined below, is achieved withthe blend set between 35 C and 45 C, with supply temperatures of 15 C coldand 65 C hot, AND, nominally equal inlet supply pressures.2.2. The blended temperature is maintained within 2 C with a 10 C change in thehot or cold supply.2.3. The wax capsule sensor effects a shut down to seepage in approximately2 seconds if the cold supply fails. Shut down to seepage is only achieved if thehot supply is 12 C above the blend temperature.3. Standards and Approvals3.1. Designed to comply with BS EN 1111 and 1287 for thermostatic mixing valves,and to be used within systems designed to BS6700.3.2. BS 6700 recommends that the temperature of stored water should never exceed65 C. A stored water temperature of 60 C is considered sufficient to meet allnormal requirements and will minimise the deposition of scale in hard waterareas.8
INSTALLATION REQUIREMENTSKey to SymbolsFloat ValveTwin Impeller PumpIsolating ValveSingle Impeller PumpThermostatic MixerTempering ValveOverflow IndicatorMini Expansion VesselPressure Reducing ValveThe Mira Excel is compatible with the following systems:Gravity fed systemThe Thermostatic Mixer MUST be fed froma cold water cistern and hot water cylinderproviding nominally equal pressure.Gas heated systemThe Thermostatic Mixer MUST be installedwith a gas water heater or combinationboiler of a fully modulating design.9
Unvented mains pressure systemThe Thermostatic Mixer can be installedwith a unvented, stored hot watercylinder.Mains pressurised instantaneous hotwater system (thermal store)The Thermostatic Mixer can be installedwith systems of this type with balancedpressures.Pumped systemThe Thermostatic Mixer can be installedwith an inlet pump (twin impeller). The pumpmust be installed on the floor next to the hotwater cylinder.90 30 -60 Air Separation10
INSTALLATIONGeneralInstallation must be carried out in accordance with these instructions, and must beconducted by designated, qualified and competent personnel.The installation must comply with the “Water Supply Regulations 1999 (Water Fittings)”or any particular regulations and practices, specified by the local water company orwater undertakers.Note: Make sure that all site requirements correspond to the information given insection: ‘Specifications’.1. The Mixer must not be installed in an area where it may freeze.2. For stud partitions alternative fixings may be required.3. Isolating valves must be installed close to the Mixer for ease of maintenance.4. Pipework must be rigidly supported and avoid any strain on the connections.5. Pipework dead-legs should be kept to a minimum.6. Supply pipework layout should be arranged to minimise the effect of other outletusage upon the dynamic pressures at the Mixer inlets.7. Inlet and outlet threaded joint connections should be made with PTFE tape orliquid sealant. Do not use oil-based, non-setting joint compounds.8. To eliminate pipe debris it is essential that supply pipes are thoroughly flushedthrough before final connection.9. Decide on a suitable position for theMixer. The position of the Mixer andthe Shower Fittings must providea minimum gap of 25 mm betweenHose Retaining Ringthe spill-over level of the showertray/bath and the handset. This is toprevent back-siphonage. For furtherinformation on the installation of yourShower Fittings, refer to the FittingsInstallation and User Guide.Note: Only use Shower Fittingsrecommended by the manufacturer25 mmor supplier.Spill OverLevel11

Excel B3. Solid and dry-lined wallsRead the section: Installation Requirements first.The built-in shower control is supplied with a support bracket that can be used toinstall the shower control into a solid or dry-lined wall structure.A foam seal is fitted to the concealing plate assembly to seal the bracket to the wallsurface (i.e. tiles). This will provide a sufficient seal for most installations to preventingress of water into the wall cavity.3.2 Determine the route for the outletpipework. When connecting to thebiv shower fittings it is recommendedthat the outlet be positioned aboveand to one side of the shower control.This is to prevent the flexible hosefrom obstructing the temperature andflow knobs of the shower control. Forfurther information on the installationof the shower fittings refer to theInstallation and User Guide.3.3 If installing the shower into a solidwall, mark an opening sufficient toaccommodate the shower controlapproximately 245 mm x 145 mm onthe surface of the wall.Alternatively, if installing theshower into a dry-lined wall, usethe installation template and markaround the outside edge.Outlet Pipe BIRBIV OutletBIV OutletHot InletCold InletShower Control145 mm3.1 Determine the route for the incominghot and cold supply pipework.Note: For some installations thevalve may want to be completelysealed within the wall and a cavityseal is available as an accessory.245 mmSpirit LevelInstallationTemplateBend tabs outwards and placethe spirit level on tabs to level the template20I&MRepro/Drawings/Orion/New Excel/Template leveling

If the hot and cold water supply pipes have been reversed duringinstallation the following procedure must be performed.1.1 Isolate the hot and cold water supplies to the shower control.1.2 Turn the flow knob fully anticlockwise to drain any water.1.3 Carefully pull off the temperature knob, indicator trim and flow lever. Removethe shroud.Note: The red and blue pillars identify the correct hot and cold inlets for thecartridge.26
1.4 Remove the four cartridge retaining screws.1.5 Pull out the cartridge. Do not remove the metal plate from the cartridgeassembly. Any residual water will drain from the body.Caution! Take care not to damage the two inlet seals or the large cartridgeseal.1.6 Rotate the cartridge through half a turn (180 ) and insert it back into the showercontrol body. The blue pillar should now be on the left side of the showercontrol. When re-inserting the cartridge, make sure that the large cartridgeseal is first located in the shower control body.1.7 Fit the four screws that retain the cartridge.1.8 Refit the shroud.1.9 Refit the controls.
