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

The Mira Silver should not be used for applications where an outlet flow control forms part of the shower fitting.

Temperature

• Maximum inlet hot water temperature: 85^oC (BS6700 recommends a maximum of 65^oC)
• Minimum temperature differential between blend and hot : 12^oC
• Hot and cold supplies to be at a nominally equal pressure

Pressure (inlet supplies)

• Minimum pressure : 0.1 bar (1m to showerhead)
• 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^oC cold and 65^oC hot, and nominally equal inlet supply pressures:

• Temperature selectable range : full cold to preset maximum (factory set is 43^oC)
• Thermostatic temperature control is achieved in the range 35^oC and 45^oC
• The blended water temperature is maintained within 2^oC with a 10^oC change in either the hot or cold supply temperatures
• Shutdown in typically two seconds if either the hot or cold supply fails provided the hot supply is more than 12^oC above the blend temperature.
• The blended water is maintained within a 2^oC range, when the pressure of either supply is reduced by 50%
• For high pressure supplies a flow regulator (supplied) should be fitted to the outlet

Accessories

Optional DCV-H: outlet double check valve for use with pressures above 0.2 bar is available, providing an alternative method of complying with Water Regulations

Guarantee

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

Application

The Mira Silver 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 Silver 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 whilst making soldered connections. Some fluxes may cause damage to plastic components.
