Specifications - Mira Extreme Thermostatic Installation And User Manual

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, the maximum stored hot water temperature should
be set to between 60 and 65°C. Such temperatures are considered sufficient
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 Extreme
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 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 effects 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 (defined 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 Duty Cycle – The Mira Extreme motor is continuously rated. The motor is
fitted with a self-resetting thermal trip protection, designed to operate if motor
temperatures become too high due to abnormally high supply voltages.
