1.3. The Mira Go is designed to stabilise temperature changes caused by water pressure fluctuations. These can result from taps being turned on or off or toilets being flushed. - Page 25 The left-hand scale is temperature rise. (Temperature rise = Showering temperature minus the incoming cold water temperature.) Example: For the Mira Go 8.5 kW on full power setting with an incoming water supply at 10°C and a showering temperature at 42°C, the temperature rise is 32°C. The flow rate is therefore, 4 l/min.
- Page 26 Lack of regular spray plate cleaning will lead to poor performance and cause early failure of the Mira Go. Refer to the Installation, Operation and Maintenance guide for the fittings.
