Fontana Gold 2-Function Thermostatic Mixer FAQ
38°C Calibration, Independent Outlet Control & Concealed Valve Commissioning
This gold concealed shower mixer combines a solid brass valve body,
automatic thermostatic temperature regulation, and two independently controlled shower-function outlets.
How should the 38°C thermostatic reference be calibrated after installation?
Operate the mixer until the outlet temperature stabilizes, measure the discharge at the 38°C index, and reposition the temperature-control handle if the measured value does not match the marked setting.
How should the two outlet branches be coordinated during concealed rough-in?
Route and label each concealed branch for its designated shower function, then confirm that each individual control activates the correct overhead shower or hand shower before wall closure.
What installation conditions support stable thermostatic regulation?
Flush both supply lines, connect hot and cold water to the designated valve inlets, and maintain balanced operating pressure so the thermostatic element can respond accurately to supply changes.
Which concealed components require testing before waterproofing?
Pressure-test the hot and cold connections, brass valve body, thermostatic cartridge housing, outlet-control seals, and both shower branches while the complete assembly remains exposed and serviceable.
