Fontana Lima Rose Gold Touch-Button Thermostatic Mixer FAQ
Three-Way Waterway Control, Ceramic Valve Core & Concealed Maintenance Access
This rose gold concealed shower mixer combines solid brass construction,
automatic thermostatic regulation, and three independently controlled water outlets.
How should the three concealed waterways be assigned during rough-in?
Connect and label the rainfall, hand-shower, and spout branches at their designated valve outlets, then verify correct touch-button indexing before waterproofing and wall closure.
When should the ceramic thermostatic valve core be installed?
Flush the hot and cold supplies independently before installing or commissioning the ceramic valve core to prevent construction debris from affecting temperature regulation or sealing surfaces.
How should outlet isolation be tested under operating pressure?
Activate each touch-button function separately and confirm complete flow through the selected outlet with no dripping, pressure migration, or hydraulic communication through inactive branches.
What concealed components must remain serviceable?
Preserve access through the supplied mounting box for the thermostatic cartridge, brass shower-switch valves, internal seals, and control assemblies without removing the completed wall surface.
