Technical Information
Principle of Operation

This fully 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 Silver should not be used for applications where an outlet flow control forms part of the showering 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

Pressure (inlet supplies)
Minimum pressure: 0.1 bar
Maximum maintained pressure: 5.0 bar
Maximum static pressure: 10 bar

Performance
The specification performance outlined below is achieve with inlet water 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 is 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 than12°C above the blend temperature.
The blended water is maintained within 2°C range when the pressure of either supply is reduced by 50%.
For high pressure supplies a flow regulator should be fitted to the outlet.

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

Application

Mira Silver is suitable for installation as part of the following plumbing systems:
Gravity fed
Fully modulating instantaneous gas heated
