Limitations of Use

The appliance must not be used for applications where an outlet flow control forms part of the shower fitting.
The appliance must not be used for applications where it may become submerged in water or where there is a risk of freezing
A water treatment device is recommended in areas where the temporary hardness is above 200ppm.
The product and its components are only suitable for normal water supplies and should be cleaned only with mild washing up detergent or soap solution.

Temperature

These electric showers work by regulating the flow of water, minimum 0.7 bar (maintained) pressure over the heating elements contained in the heater tank of the shower unit.

Power selection is chosen by turning the top control knob

Water flow is started or stopped by depressing the start / stop button

The showering temperature is adjusted by turning the temperature control knob, which varies the flow of cold water across the elements. The slower the rate of flow, the warmer the water and vice versa. Spray plates in shower handsets should always be kept clean to maintain a consistent flow and assist in temperature control.

All Mira electric showers are designed to stabilise temperature changes caused by water pressure fluctuations. These can result from taps being turned on or off or toilets flushed. Under such conditions, average shower temperatures will be held within a 6^oC band, provided that the minimum required pressure is maintained.

he design of most popular electric showers does not allow for thermostatic control of the showering temperature, and as such, they are unable to react to changes in temperature caused by a change in mains voltage, or in the incoming water temperature. For thermostatically controlled electric shower, refer to Sport Thermostatic, Sport, Advance ATL, Azora and Galena.

The temperature of incomign water will vary between summer and winter and therefore, the temperature control knob will need to be marginally adjusted to take account of these seasonal conditions. The length of dead leg of the cold pipe or its proximity to hot pipes may affect the showering temperature.

If the watertemperature reaches an unsafe level, the thermal switch assembly turns off the elements. As the water temperaturefalls the elements will be turned on. The switch will cycle on / off / on if the flow rate is not increased and the shower temperature reduced. The 'Overheat' neon on the Mira Sport 10.8 wll provide a visual indication of this condition.

When the shower is first turned on or a different temperature is selected there will be a slight delay before the shower temperature changes, to allow the previously heated water to be used up.

Pressure

Minimum maintained pressure : 0.7 bar
Minimum static pressure : 0.2 bar (to keep Solenoid valve closed)
Maximum static pressure : 10 bar

Accessories

Optional DCV-H: outlet double check valve providing an alternative method of complying with UK water regulations

Guarantee

Guaranteed for two years from date of purchase against faulty materials or workmanship. Optional extended warranty available. Contact Mira Customer Support.

Application

The Mira Sport is suitable for installation as part of the following plumbing systems:

Mains cold water pressure

Installation - Plumbing

Surface-mounted unit

Inlet connection : 15mm plastic swivel stub for use with a push fit or compression fitting (not supplied) from the top, bottom or back.

Outlet connection : 1/2" BSP male

The plumbing installation must comply with the requirements of UK water Regulations / Bylaws (Scotland), Building Regulations / Bylaws (Scotland) Building Regulations or any particular regulations and practices, specified by the local water company or water undertakers. The installation should be carried out by a plumber or a contractor who is registered or is a member of an association

Protect the product from damage whilst making soldered connections. Some fluxes cause damage to plastic components

Installation - Electrical

The appliance must be earthed

This appliance is intended to be permanently connected to the fixed electrical wiring of the mains system, in accordance with the current edition of 'The Plugs and Sockets etc. (Safety) regulations' in force at the time of the installation.

The Mira Sport 7.5kW and Mira Sport 9.0kW requires a 40 Amp fuse. The Mira Sport 9.8kW will require a 45Amp fuse

The terminal block will not accept cable larger than 16mm²

Maximum ambient temperature for the appliance whilst in use is 30^oC

The appliance will provide satisfactory performance with an incoming electrical supply voltage of 230V ±10%. The supply voltage will affect the flow rate.

The installation must comply with 'Requirements for Electrical Installations' (commonly referred to as the IEE Wiring Regulations) or any particular regulations and practices specified by the local electricity supply company.

A separate, permanently connected supply must be taken from the consumer unit to the appliance via a double pole switch with at least a 3mm contact separation.

The switch can be a ceiling-mounted pull-cord switch or a wall mounted switch in the appropriate zone (see Wiring regulations)

We recommend the inclusion of a 30mA residual current device (RCD). This may be a requirement of Wiring Regulations.
