P3838_3 Mira Fino.pmd - QS Supplies

Gravity fed showers - The shower control MUST be fed from a cold water storagecistern and hot water cylinder providing nominally equal pressures.Mains pressurised instantaneous hot water shower, heated from a thermal storePackages of this type, fitted with a tempering valve can be used.A drop tight pressure reducing valve MUST be fitted if the supply pressures exceed 5 barmaintained.An expansion vessel MUST be fitted (and regularly maintained) if any form of backflowprevention device is fitted, e.g. non-return valve, PRV. This will ensure that excessexpansion or pulse pressures do not damage the product or the plumbing system. Theexpansion vessel may already be fitted externally or internally within the thermal store(check with thermal store manufacturer).COLDHOT11
