Mira Elite ST Electric Shower

Designed to work off a gravity-fed system, the Mira Elite ST is ideal for areas where mains water pressure is either too low or erratic to operate a standard electric or mixer shower. With a built in pump to boost the cold water supply, the Mira Elite ST produces consistent water delivery anytime.

Mira Elite ST- 9.8kW

240V AC 9.8kW, (230V AC 9.0kW) heater with a Mira Logic Adjustable spray showerhead with four different spray actions (Start, Soothe, Force and Eco). Individual lights indicate 'Power' and 'Low Flow'. Supplied complete with hose, clamp bracket, slide bar and integrated hose retaining ring and soap dish.

Limitations of Use

• Do not connect to a mains fed water supply. Such a connection will damage the appliance and is not covered under the manufacturer's guarantee
• The Elite ST is not an instantaneous power shower and flow rates will be similar to other 9.8kW electric showers
• 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 an outlet flow control forms part of the shower fitting
• The appliance must not be used for applications where the appliance 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

• Pumped electric showers work by taking cistern fed cold water and passing it over the heating elements contained in the heater tank of the shower appliance
• 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
• The holes in the spray plate of the showerhead should always be kept clear to maintain a consistent flow and assist in temperature control.
• The temperature of gravity fed 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 water supply 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. When the water temperature falls 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 'Low Flow' light on the Mira Elite ST will 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 : 0.008 bar (80mm)
• Maximum static pressure : 1.0 bar

Accessories

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

Application

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

• Mains cold water pressure

Installation - Plumbing

Surface-mounted unit

Inlet connection : 15mm inlet compression connector which swivels to accept plumbing supplies 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

This product must have its own separate supply from the cold water storage cistern, avoiding any other draw-offs, long horizontal pipe runs and 90^o elbows

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 'The Plugs and Sockets etc. (Safety) regulations in force at the time of installation.

The appliance requires a 45 Amp supply fuse

The terminal block will not accept cable larger than 16mm²

Maximum ambient air 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.
