Fontana Rose Gold 2-Function Thermostatic Mixer FAQ
38°C Temperature Calibration, Dual-Outlet Control & Concealed Valve Testing
This rose gold concealed shower mixer combines a solid brass valve body,
automatic thermostatic regulation, and two independently controlled shower-function outlets.
How should the 38°C thermostatic reference be calibrated after installation?
Run the mixer until the outlet temperature stabilizes, measure the discharge at the marked 38°C position, and realign the control handle if the measured temperature differs from the reference index.
How should the two concealed outlet branches be assigned?
Route and label each branch for its designated shower function, then verify that each individual push control activates the correct overhead shower or hand shower before closing the wall.
What supply preparation supports accurate thermostatic regulation?
Flush the hot and cold supply lines, connect them to the designated valve inlets, and maintain balanced operating pressure so the thermostatic cartridge can respond consistently to supply changes.
Which concealed components must be tested before waterproofing?
Pressure-test the inlet connections, brass valve body, thermostatic cartridge chamber, function-control seals, and both concealed outlet branches while the complete assembly remains exposed.
