Thank you for purchasing a quality Mira product. To enjoy the full potential of yournew shower, please take time to read this guide thoroughly, having done so, keep ithandy for future reference.

The Mira Event is an all-in-one power shower with an integral mains voltage pumpunit, with separate controls for flow and temperature.

The Event features outlet flow control and a 15mm dual entry push-fit inlet manifoldto enable the appliance to support various inlet supply configurations. The manifoldincorporates inlet filters and check valves. The thermostatic mixer assemblyincorporates a wax capsule temperature sensing unit and ceramic disc technologyfor flow control.

Designed to be surface mounted the Event is supplied complete with an adjustablespray handset with three different spray actions (start, champagne, massage) andan economy setting, flexible hose, adjustable clamp bracket assembly, slide bar andsupports, soap dish and hose retaining ring. The Event is available with the showerfittings in white/chrome finish or all white finish.

The Event is not suitable for installation in institutional/commercial applications or foruse with mains water pressure applications, e.g. Instantaneous electric heaters,instantaneous gas water heaters, unvented mains pressure systems, pumpedshower systems and some combination type storage systems.

Section 1

If you experience any difficulty with the installation or operation of your new MiraEvent, then please refer to the back cover of this guide for Caradon Mira contacttelephone and fax numbers.

3.53.53.53.53.5 Avoid layouts where the hose will be sharply kinked. This may reduce thelife of the hose.

3.63.63.63.63.6 The storage cistern should have a minimum storage capacity of 230 litres toprovide adequate showering time and to comply with BS6700 (1987).Insufficient storage may result in the pump being run dry.

3.153.153.153.153.15 If the appliance is installed on a common supply which feeds an adjacenttap, the maximum static inlet pressure for the appliance will, under certaincircumstances be exceeded; the action of closing the tap can cause a pulsein the supply pressure which will result in damage to the appliance. This canbe resolved by the installation of a suitably sized mini expansion vessel,sited as close as possible to the tap and pressurised to 0.5 bar.

The Mira Event features a 15mm dual entry push-fit inlet manifold to enable theappliance to support three inlet supply configurations. Choose the appropriate inletsupply configuration to suit your installation before proceeding to install the appliance.

The inlet manifold is factory fitted with two inlet blanking plugs fitted to the top inletsand allows for a bottom inlet suppy configuration. The blanking plugs can berepositioned to suit the installation's supply pipework configuration. A push-fit releasetool is provided which can be used to lever out the blanking plugs. Refer to “Change“Change“Change“Change“Changethe Inlet Supply Ports”the Inlet Supply Ports”the Inlet Supply Ports”the Inlet Supply Ports”the Inlet Supply Ports” for the complete procedure.

The Event will accept three inlet supply configurations:-

Top inlet supply – Seal off bottom inlets of manifold.Bottom inlet supply – Seal off top inlets of manifold.Back inlet supply – Seal off bottom inlets of manifold.

To enhance the final appearance of the appliance the Mira Event case features tworemovable inlet blanking plates which are factory fitted in to the top and bottom of thecase.

These blanks can be removed as follows to allow the three inlet supplyconfigurations:-

Top inlet supply – Remove top inlet blanking plate.Bottom inlet supply – Remove bottom inlet blanking plate.Back inlet supply – Removal of top or bottom inlet blanking plates not required.

The Mira Event case also catersfor top, bottom or back electricalsupply cable entry.In the case of top or bottomentry this is achieved by cuttingaway and trimming thinnedsections in the top and bottom ofthe case. The cable can then befitted into a moulded channelrunning up and down the back ofthe case.

Site conditions and personal preference may dictate that themaximum temperature has to be reset.

To reset the maximum temperature ensure that an adequate supply of hot water isavailable at a temperature at least 12°C in excess of that required from theappliance, and the temperature control knob is set to the full hot position. Turn theflow control knob fully anti-clockwise then check the temperature at the dischargepoint (allow sufficient time for hot water to reach the hot inlet of the appliance).If the temperature is correct, turn the flow control knob fully clockwise to the offposition as no further adjustment is necessary.
