Fontana Lima Gold Touch-Button Thermostatic Mixer FAQ
Three-Way Flow Selection, Thermostatic Regulation & Concealed Service Access
This gold concealed shower mixer combines a solid brass valve assembly,
automatic thermostatic control, and three touch-button-operated water outlets.
How should the three waterway connections be assigned during rough-in?
Connect and label the rainfall, hand-shower, and spout branches at their designated concealed outlets, then confirm correct touch-button indexing before waterproofing and wall closure.
How should the thermostatic mixing assembly be commissioned?
Flush both supply lines independently, establish stable hot and cold inlet conditions, and verify consistent mixed-water temperature while each of the three outlets operates under flow.
How should the brass shower-switch valves be validated?
Cycle each touch button repeatedly and confirm positive engagement, full outlet shutoff, correct function selection, and no pressure transfer or cross-flow into inactive branches.
What service access must remain after the finished wall is completed?
Keep the supplied mounting box accessible so the thermostatic cartridge, brass switch valves, internal seals, and control components can be serviced without demolishing the wall finish.
