Fontana Champagne Brass 2-Function Thermostatic Mixer FAQ
38°C Safety Calibration, Dual-Outlet Isolation & Concealed Valve Testing
This champagne brass concealed shower mixer combines automatic thermostatic regulation,
two independently controlled outlets, and a solid brass valve body for stable mixed-water delivery.
How should the 38°C temperature reference be commissioned?
Operate the mixed-water outlet until temperature stabilizes, verify the discharge with a calibrated thermometer, and realign the control handle if the measured output differs from the 38°C index.
How should the two shower-function outlets be hydraulically verified?
Activate each outlet independently, confirm correct rough-in routing and stable flow, and verify that the inactive branch remains fully isolated without pressure migration or concealed cross-flow.
What supply preparation is required before cartridge commissioning?
Flush the hot and cold lines independently, verify hot-left and cold-right orientation, remove construction debris, and maintain balanced inlet pressure before operating the thermostatic cartridge.
Which concealed components require testing before wall closure?
Pressure-test the inlet unions, brass valve body, thermostatic cartridge chamber, outlet-control valves, threaded seals, and both concealed outlet branches while every connection remains accessible.
