Fontana Elite Champagne 3-Function Thermostatic Mixer FAQ
Three-Outlet Control, 20–50°C Regulation & Concealed Valve Commissioning
This champagne wall-mounted shower mixer combines a solid brass concealed valve,
a 1.38-inch ceramic cartridge, and three individually controlled shower-function outlets.
How should the three concealed outlets be assigned during rough-in?
Route and label each 1/2-inch outlet branch for its designated shower function, then verify that every control activates the correct rainfall, hand-shower, or auxiliary outlet before wall closure.
How should the ceramic temperature cartridge be commissioned?
Flush both supply lines, operate the valve through its 20–50°C adjustment range, confirm smooth cartridge movement, and align the temperature control only after the mixed-water output has stabilized.
How should outlet isolation be checked under operating pressure?
Activate each function independently and confirm stable discharge from the selected branch without pressure migration, cross-flow, dripping, or unintended delivery through either inactive outlet.
Which concealed connections require testing before waterproofing?
Pressure-test the hot and cold inlets, solid brass valve body, ceramic cartridge housing, three function-control seals, and every 1/2-inch outlet connection while the assembly remains fully accessible.
