Mira Coda (Valve Only)
Surface mounted shower control
Principle of Operation
This fully thermostatic shower control 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.
Limitations of Use
The Mira Coda should not be used for applications where an outlet flow control forms part of the shower fitting. 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
- Maximum inlet hot water temperature: 90oC for short periods (BS6700 recommends a maximum of 65oC)
- Minimum inlet hot water temperature : 55oC
- Minimum temperature differential between blend and hot: 12oC
- Hot and cold supplies to be at 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
- Flow rate is fully adjustable
- Temperature is user selectable from full cold to a factory set safe maximum, which can be over-ridden by the user if required
- Wax capsule thermostatic cartridge technology controls outlet temperature stability between 20oC and 50oC
- Optimum thermostatic control between 35oC and 45oC (the specification outlined below is temperatures of 15oC cold and 65oC hot and nominally equal inlet supply pressures)
- The blended water temperature is maintained within 2oC with a 10oC change in either the hot or cold supply
- The Mira Coda will effect a shutdown in typically two seconds if either the hot or cold supply fails (note shutdown will only occur if the hot supply is more than 10oC above the blend temperature).
Accessories
Optional DCV-H: outlet double check valve for use with pressure 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 Coda 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 Coda 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 can cause damage to plastic components.
