Specications
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su󰀩cienttomeet
all normal requirements and will also minimise the deposition of scale in hard
water areas.
1.3. Temperature control – To obtain the full listed performance the Mira Event XS
should be installed, operated and maintained in accordance with this guide.
1.4. The performance outlined below is achieved with a showering temperature of
between 35° and 45°C selected and water supplies of 15°C cold and 65°C hot
with nominally equal pressures.
1.4.1 The maximum temperature stop is set to 41°C. Depressing the
override button overrides the maximum temperature and the showering
temperature can be increased by 5°C to approximately 46°C.
1.4.1. The blended water temperature is maintained within 1°C with a 10°C
change in the hot or cold water supply.
1.4.2. Thesensore󰀨ectsashutdowntoseepageinapproximately2seconds
if the cold supply fails.
1.4.3. Shut down to seepage is achieved even if the hot supply is only 12°C
above the blend temperature.
1.4.4. The blended water temperature is maintained within 1.5°C when the
pressurebetweeninletandoutletishalved(denedasapressureloss
ratio of 2:1) on either the hot or cold side.
1.5. Maximum static inlet pressure – 1 bar or 10 m (supplies must be gravity-fed
atnominallyequalpressures).Refertosection:'Installation Requirements,
Plumbing'.
1.6. 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. Maximum recommended inlet pressure – 0.5 bar or 5 m (supplies must be
gravity-fed at nominally equal pressures).
1.8. MinimumFlowRate–8L/Min(withastaticinletpressureof0.1bar)andare
for valve only.
MaximumFlowRate–16L/Min(withastaticinletpressureof0.1bar).
 FlowRatesmayvaryduetodi󰀨erencesinsupplypressuresandwhenshower
ttingsinstalled.

temperatures become too high due to abnormally high supply voltages.
1.10.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a󰀨ect
the perceived noise level; solid walls will provide a quieter operation.
