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

- 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.
These electric showers work by regulating the flow water, minimum 0.7 bar (maintained) pressure (8.5, 9.5), 1 bar (10.8), over the heating elements contained in the heater tank of the shower unit.
Water flow is started or stopped by depressing the start / stop button
Power selection is chosen by turning the top control knob
The showering temperature is adjusted by turning the temperature control knob, which varies the flow of coldwater 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 6oC band, provided that the minimum required pressure is maintained.
The design of most popular electric shower 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 showers, refer to MIra Sport Thermostatic, Mira Escape, Mira Advance, Mira Azora and Mira Galena.
The temperature of incoming water will vary between summer and winter, and therefore, the temperature control knob will need to be 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 water temperature reaches an unsafe level, the thermal switch assembly turns off the elements. As the water temperature falls the elemetns will be turned on. The switch will cycle on / off / on if the flow-rate is not increased, adn the shower temperature reduced.
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.
- Minimum maintained pressure : 0.7 bar (8.5, 9.5), 1 bar (10.8)

The new Mira Vie is suitable for installation as part of the following plumbing systems:
- Mains cold water pressure
Installation – Plumbing
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 appliance requires either a 40Amp supply fuse (8.5) or 45 Amp supply fuse (9.5, 10.8)
The terminal block will not accept cable larger than 16mm2
Maximum ambient temperature for the appliance whilst in use is 30oC
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.
