Fontana Pro Flow Commercial Sensor Faucet FAQ
4-Inch Minispread Deck Layout, Infrared Activation;
Ceramic Valve Control & Automatic Flow Regulation
The Fontana Pro Flow FS-CR9122 combines infrared touchless
operation, ceramic valving, deck mounting, and automatic
commercial water control.
How should the 4-inch minispread layout be coordinated before installation?
Confirm the deck openings, basin centerline, countertop thickness,
and available service clearance before securing the faucet. The
minispread arrangement should remain square to the basin so the
outlet aligns with the primary hand-washing zone while concealed
connections remain accessible below the deck.
How should the ceramic valve be protected during first commissioning?
Flush the water supply before making the final connections to remove
construction debris, pipe scale, and sealing residue. Cycle the faucet
repeatedly after startup and verify smooth opening, stable discharge,
and complete closure. Irregular flow or delayed shutoff should prompt
inspection of the valve path and outlet.
How should automatic shutoff performance be tested in a commercial restroom?
Perform repeated hand-entry and withdrawal cycles under normal supply
conditions. Water should begin when the user enters the sensing field
and stop automatically when the user leaves. Test several approach
angles to confirm reliable interruption without extended run-on or
unintended activation between users.
How should the infrared sensor be coordinated with reflective basin surfaces?
Complete sensor testing after mirrors, lighting, countertop finishes,
and basin accessories are installed. Polished surfaces can influence
infrared return signals, so verify activation from several hand
positions and check for false triggering from the basin wall,
backsplash, or nearby reflective objects.
