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 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°–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 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 “

Installation Requirements –

Plumbing

” for further advice.

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 "

Installation Requirements – Plumbing

" for

further advice.

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).
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.
