Mira Element Mixer Shower Ss Bir – 1.1656.003

Bringing both thermostatic temperature and flow control onto one simple to use dial, the Mira Element makes showering beautifully simple – and stunningly affordable.

• Thermostatic temperatures stability keeps showering safe for all the family
• One single control for flow and temperature creates a clean, minimal look
• Choose BIV or EV models for a 4-spray showerhead with a partial rub-clean rubbing nozzles, or a BIR single spray showerhead
• Can be fitted to falling, rising and rear water supplies
• Approved to TMV2 standards, which means you know its thermostatic control is the very highest quality
• Clean chrome finish

Technical Information
Principle of Operation
This full thermostatic shower control turns flow on/off and mixes hot and cold water to the desired showering temperature. It automatically compensates for variation in both the temperature and pressure of the inlet water supplies to maintain the blend temperature. If either supply fails the shower control will automatically shut down to prevent scalding.

Limitations of Use
Mira Element should not be used for applications where an outlet flow control forms part of the shower fitting.

Temperature
Maximum inlet hot water temperature: 85°C (BS6700 recommends a maximum of 65°C).
Minimum temperature differential between blend and hot: 12°C
Hot and cold supplies to be a nominally equal pressure
Maximum pressure imbalance: 5:1

Pressure (inlet supplies)
Minimum pressure: 0.1 bar
Maximum maintained pressure: 5.0 bar
Maximum static pressure: 10.0 bar

Performance
The specification performance outlined below is achieved with inlet water supply temperatures of 15°C cold and 65°C hot, and nominally equal inlet supply pressures:
Temperature selection range: full cold to preset maximum (factory set 43°C).
Thermostatic temperature control is achieved in the range 35°C – 45°C
The blended water temperature is maintained within 2°C with a 10°C change in either the hot or cold supply temperatures.
Shutdown to seepage in typically two seconds if either the hot or cold supply fails provided the hot supply is more than 12°C above the blend temperature.
The blended water is maintained within a 2°C range when the pressure of either supply is reduced by 50%.
For high pressure supplies a slow regulator should be fitted to the outlet.

Guarantee
Guaranteed for five years from date of purchase against faulty materials or workmanship.

Application
Mira Element is suitable for installation as part of the following plumbing systems:
Gravity fed
Fully modulating instantaneous gas heated
Mains pressurised (heated from a thermal store)
Unvented mains pressure
Pumped

When the Mira Element is used with mains pressure appliances at pressures above 5.0 bar maintained, a drop-tight pressure reducing valve must be installed to maintain performance.

Installation
The plumbing installation must comply with the requirements of UK Water 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 contractor who is registered or is a member of an association.
Protect the product from damage when making soldered connections. Some fluxes may cause damage to plastic components.
