Specifications - Mira Vigour Installation And User Manual

SPECIFICATIONS

Electrical
Power supply - 230-240 V at 50 Hz, fused at 3 Amps, via a double pole fused switch
(not supplied) with a minimum contact separation of 3 mm for each contact.
Electrical Connections - Terminal block will accept cable up to 2.5 mm². Minimum cable
size (cross-sectional area) required under normal installation conditions is 1 mm .
2
Power Consumption - 150 W maximum.
Plumbing Connections
Inlet Connections - 2 x 15 mm Push-fit manifold.
Outlet Connection - 1/2" BSP male.
Operating Parameters
Cold water temperature - Maximum inlet temperature 30 °C
Hot water temperature - Maximum inlet temperature 65 °C
Warning! For safety reasons set the maximum temperature of the stored hot water to
between 60 and 65 °C. Such temperatures are considered sufficient to meet all normal
requirements and will minimise the deposition of scale in hard water areas.
Temperature Control - The maximum temperature stop is set to 41 °C. Depressing
the override button overrides the maximum temperature and allows the showering
temperature to be increased by 5 °C to approximately 46 °C.
The showering temperature will be maintained to within 1 °C of selected temperature
with a 10 °C change in the hot or cold water supply.
If the cold supply fails the thermostatic mixer will shut down flow of water to seepage
levels in approximately 2 seconds. The hot supply must be at least 12 °C above the
blend temperature for shut down to seepage to occur.
The showering temperature will be maintained to within 1.5 °C of the selected showering
temperature when the pressure between inlet and outlet is halved on either the hot
or cold side.
Operating pressure
Minimum maintained pressure - 0.1 kPa (0.01 bar) or 100 mm head of water.
Maximum maintained pressure - 50 kPa (0.5 bar).
Maximum static pressure - 100 kPa (1 bar) or 10 m head of water.
Duty Cycle - The Mira Vigour Thermostatic Power Shower pump is now continuously
rated. The motor is fitted with a self-resetting thermal trip, designed to operate if motor
temperatures become too high due to abnormally high supply voltages.
Noise - The acoustic noise from the pump motor has been reduced with the use of
anti-vibration rubber feet and rubber wall plugs. The type of wall the appliance is fixed to
will also affect the perceived noise level; solid walls will provide a quieter operation.
Standards
The Mira Vigour Thermostatic Power Shower complies with all relevant directives for
CE marking.
