INTRODUCTION
Thank you for purchasing a quality Mira product. To enjoy the full potential of your new shower, please take time to read this guide thoroughly, and keep it handy for
future reference.
The Mira Event XS is a surface mounted all-in-one manual power shower. It is designed for use with a mains voltage electrical supply and gravity fed hot and cold water supplies. It features a built-in pump unit, manual mixer assembly and separate controls for ow and temperature.
The product is tted with a 15 mm dual entry push-t inlet manifold which allows pipe connections to the top, bottom or rear of the power shower. The inlet manifold also contains inlet lters and check valves.
The shower control is supplied with Mira Logic power shower ttings. These ttings consist of an adjustable spray handset with four different spray actions (start, champagne, massage and economy), exible hose, adjustable clamp bracket assembly, slide bar and supports, hose retaining ring and wall mounted soap dish. The ttings are available in a white/chrome or all white nish.
The Mira Event XS is not suitable for use in institutional/commercial applications. It must not be used with mains water pressure applications; for example, instantaneous electric heaters, instantaneous gas water heaters, unvented mains pressure systems, pumped shower systems and some combination-type storage systems.
Guarantee
Mira Showers guarantee the Mira Event XS against any defect in materials or
workmanship for a period of one year from the date of purchase.
For terms and conditions refer to the back cover of this guide.

SPECIFICATIONS
1. General
1.1. Ambient temperature – Maximum recommended ambient temperature for the
appliance is 30°C.
1.2. Maximum recommended hot water temperature – 65°C.
Warning! For safety reasons set the maximum stored hot water temperature
to between 60 and 65°C. Such temperatures are considered sufcient to meet all normal requirements and will also minimise the deposition of scale in hard
water areas.
1.3. Temperature control - To obtain full performance the Mira Event XS should be installed, operated and maintained in accordance with this guide.
1.4. Maximum static inlet pressure - 1 bar or 10 m (supplies must be gravity-fed at nominally equal pressures). Refer to section: 'Installation Requirements,
Plumbing'.
1.5. Maximum recommended inlet pressure - 0.5 bar or 5 m.
1.6. Minimum static inlet pressure - 0.008 bar or 80 mm (required to prime
the integral centrifugal pump). The minimum static pressure will increase for long supply pipe lengths. Refer to section: 'Installation Requirements,
Plumbing'.
1.7. Minimum Flow Rate - 8 l/Min (with a static inlet pressure of 0.1 bar).
Maximum Flow Rate - 16 l/Min (with a static inlet pressure of 0.1 bar).
Flow Rates may vary due to differences in supply pressures.
1.8. Duty Cycle - The Mira Event pump is continuously rated. The motor is tted with a self-resetting thermal trip, designed to operate if motor temperatures become too high due to abnormally high supply voltages.
1.9. Noise - The Mira Event XS is supplied with anti-vibration rubber feet and rubber wall plugs that isolate the unit from the wall in order to minimize the amount of noise transmitted. The type of wall the Mira Event XS is xed to will also affect the perceived noise level; solid walls will provide a quieter operation.
2. Plumbing
2.1. Inlet – 15 mm Push-t inlet manifold.
2.2. Outlet – 1/2" BSP to BS2779.

3. Electrical
3.1. Appliance power supply – 230–240 V, 50 Hz, fused at 3 Amps, via a double
pole switched fused connection unit (not supplied) with a minimum 3 mm contact separation in each pole.
3.2. Power supply connection – The Mira Event XS is tted with a terminal block which will accept cable up to 2.5 mm². Minimum cable size (cross-sectional area) required under normal installation conditions is 1 mm2.
3.3. Absorbed power - Approximately 150 W under normal working conditions.
4. Standards
4.1. The Mira Event XS complies with all relevant directives for CE marking.

INSTALLATION REQUIREMENTS
1. General
1.1. Do not take risks with plumbing or electrical equipment.
1.2. Do not install the Mira Event XS in a position where it could become frozen.
1.3. Isolate electrical and water supplies before proceeding with the installation of
the Mira Event XS.
1.4. The shower control must be fed from a cold water storage cistern and hot water
cylinder providing nominally equal pressures.
1.5. The installation must be carried out by a competent installer.
1.6 Decide on a suitable position for the Mira Event XS (minimum distance of 200
mm from the ceiling to allow for tting and removal of the cover). The position of the Mira Event XS and the shower ttings must provide a minimum gap of 25 mm between the spillover level of the shower tray/bath and the handset. This is to prevent back siphonage.
1.7. The Mira Event XS must be tted onto the nished wall surface i.e. on top of the tiles. Do not t the Mira Event XS to the wall and then tile up to the sides of the casing. (Small pillars moulded on the back of the case allow air to circulate and water to drain from behind the appliance).
1.8. When tting the Mira Event XS with wall entry inlet supplies it is recommended that the supply pipework is sealed to the wall to prevent water from leaking
back into the wall.
1.9. In solid wall installations the supply pipework should be installed within ducting to allow some free lateral movement when making supply connections.
2. Electrical
2.1. Do not turn on the electrical supply until the plumbing has been completed.
2.2. The mains supply must be 230-240 V at 50 Hz connected to the appliance
via a double pole switched 3 Amp fused connection unit (not supplied) with a minimum 3 mm contact separation gap in each pole.
2.3. Fuses do not give personal protection against electric shock.
2.4. The Mira Event XS must be earthed by connecting the supply-cable earth
conductor to the earth terminal.
Supplementary bonding: Within the bathroom or shower room, all accessible
conductive parts of electrical equipment and extraneous conductive parts that are likely to introduce earth potential, must be electrically bonded to earth using a minimum cable size of 4.0 mm
2
if the cable is not mechanically protected
(2.5 mm2 if mechanically protected).
2.5 The minimum cable size (cross-sectional area) required is 1 mm2 under normal
conditions of installation.
11
2.6. A 30mA residual current device (RCD) must be tted. This may be part of the consumer unit or a separate unit.
3. Plumbing
3.1. Do not use excessive force when making connections to the exible hoses or
handset, nger tightness is sufcient.
3.2. Do not solder supply pipework with the Mira Event XS connected. Heat transmitted through the pipework will melt the inlet manifold.
3.3. The storage cistern should have a minimum storage capacity of 230 litres to provide adequate showering time. Insufcient storage may result in the pump
being run dry.
3.4. Avoid layouts where the hose will be sharply kinked. This may reduce the life
of the hose.
3.5. No form of ow control should be tted to the outlet of the appliance.
3.6. Fit non-restrictive (free-owing) isolating valves to the inlet pipework in an easily
accessible position. These valves will allow the water supply to be turned off to the Mira Event XS, for maintenance purposes.
3.7. When using surface mounted inlet supply pipework the use of polyethylene plastic pipe suitable for hot water is recommended to enhance the appearance of the nished installation. Internal pipe supports (not supplied) should be used with this type of pipe.
3.8. Only use the Mira showerhead supplied with this appliance.
3.9. If the appliance is installed on a common supply ensure the appliance is the
rst take-off from the supply and is not inuenced by the operation of any other appliance.
3.10. If the appliance is installed on a common supply which feeds an adjacent tap, the maximum static inlet pressure for the appliance will, under certain circumstances, be exceeded. The action of closing the tap can cause a pulse in the supply pressure which will result in damage to the appliance. This can be 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.
3.11. Long pipe runs and excessive use of 90° elbows will signicantly reduce the head available to supply the Event XS. If the effective head is less than 80 mm
then:
3.11.1 The expected ow rate may not be achieved.
3.11.2 Air may be drawn into the hot supply from the vent pipe, causing
spluttering and temperature uctuations at the handset.
