Fontana Domodossola Chrome Touchless Faucet FAQ
ToF/IR Field Control, Spout Projection & Concealed TMV Coordination
The Fontana Domodossola Chrome touchless faucet combines wall-mounted
architecture, fast ToF/IR hand detection, hot-and-cold water capability,
and automatic shutoff for hygienic operation in institutional, commercial,
hospitality, and high-traffic public restroom environments.
How should the ToF/IR sensing field be validated after the basin and wall finishes are installed?
Commissioning should confirm that the detection field captures normal hand entry beneath the spout without responding to the basin wall, backsplash, mirror edge, or reflective chrome accessories. Testing the completed environment helps preserve fast activation while limiting false triggering.
How should installers select between the 7.09-inch and 8.66-inch spout projections?
The selected projection should place the water stream near the basin drain while maintaining adequate hand clearance. Basin setback, wall thickness, rim geometry, and splash-zone containment must be coordinated before the concealed outlet position is finalized.
What is required when integrating the faucet with a thermostatic mixing valve?
The concealed TMV should receive balanced hot and cold supplies, remain accessible for calibration and servicing, and be adjusted under flowing conditions. The mixed-water line must then be flushed before connection to protect the faucet valve and outlet from installation debris.
How can anti-false-triggering performance be checked during final acceptance testing?
Technicians should cycle the faucet from multiple hand-entry angles, remove their hands rapidly, and operate nearby dispensers and fixtures. Reliable acceptance requires immediate activation, prompt shutoff, no spontaneous cycling, and stable flow during repeated use.
