Fontana Brushed Nickel 2-Function Thermostatic Mixer FAQ
Thermostatic Calibration, Dual-Outlet Control & Concealed Valve Testing
This brushed nickel concealed shower mixer combines a solid brass valve body,
automatic thermostatic regulation, and two independently controlled shower-function outlets.
How should the thermostatic temperature control be calibrated after installation?
Operate the valve until the temperature stabilizes, measure the mixed-water output at the marked 38°C position, and realign the control handle if the measured temperature differs from the index.
How should the two outlet branches be coordinated during rough-in?
Route and label each concealed outlet for its assigned shower function, then verify that each push control activates the correct overhead shower or hand shower before wall closure.
What supply conditions support stable thermostatic performance?
Connect the hot and cold supplies to their designated inlets, flush both lines thoroughly, and maintain balanced operating pressure so the thermostatic cartridge can regulate temperature consistently.
Which concealed components require pressure testing before tiling?
Test the supply connections, brass valve body, thermostatic cartridge housing, two outlet controls, threaded seals, and both concealed outlet branches while the assembly remains fully accessible.
