Plumbing System Compatibility

• Fully modulating combi boilers and instantaneous gas water heaters
• Gravity-fed hot and cold water supply
• Gravity-fed hot and cold pumped water supply
• Mains pressure hot and cold - unvented
• Mains pressure thermal store

Limitations of Use

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

Application

Mira Miniduo 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 Miniduo is used with mains pressure appliances at pressures above 5 bar maintained, a drop-tight pressure reducing valve must be installed to maintain performance.

Supply Conditions

• Recommended hot inlet supply temperature 55-65^oC
• Maximum hot temperature 85^oC (maximum recommended is 65^oC Ref BS6700)
• Recommended cold temperature 5-25^oC
• Minimum cold temperature 1^oC
• Hot and cold supplies to be at a nominally equal pressure
• Min maintained pressure 0.1 bar (1m to showerhead).
• Max maintained 5.0 bar
• Max static 10.0 bar

Performance

The specification performance outlined below is achieved with inlet water supply temperatures of 15^oC cold and 65°C hot, the mixed temperature in the range 35°C - 45°C and nominally equal inlet supply pressures:

• Temperature selectable range : full cold to preset maximum (factory set is 43°C) but can be easily reset depending on site conditions
• The blended water temperature is maintained within 2°C with a 10°C 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% (0.5 bar maintained)
• For high pressure supplies a 12l min / 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 (to the hose retaining ring) of complying with Water Regulations

Universal retrofit kit with adjusting elbows, designed to allow the thermostatic mixer to accept pipework centres between 133mm - 153mm and a mounting plate designed to hide the majority of previous valve screw holes.

Guarantee

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