Fontana Halluin Matte Black 3-Function Thermostatic Mixer FAQ
Triple-Outlet Isolation, 35 mm Ceramic Control & Concealed Valve Commissioning
This matte black wall-mounted shower mixer combines a solid brass concealed valve,
a 35 mm ceramic cartridge, and three independently controlled shower-function outlets.
How should the three concealed outlet branches be indexed?
Label each 1/2-inch outlet during rough-in and verify that every control operates its assigned rainfall, hand-shower, or auxiliary branch before waterproofing and trim installation.
How should the 35 mm ceramic cartridge be commissioned?
Flush the hot and cold supplies before cartridge operation, cycle the temperature control through its 20–50°C range, and confirm smooth movement without debris restriction or control binding.
How should inactive-outlet isolation be verified?
Operate each shower function independently under normal supply pressure and confirm that the two inactive branches remain sealed without dripping, cross-flow, or pressure-induced discharge.
Which concealed components require testing before wall closure?
Pressure-test the solid brass valve body, hot and cold inlets, cartridge chamber, three function-control seals, and every 1/2-inch outlet connection while the rough-in remains accessible.
