Engineering Questions Coordination before installation
Which disciplines should coordinate the system?Architectural, interior, plumbing, electrical, accessibility and millwork requirements should be reviewed together using the exact approved faucet and dispenser models. What should an engineering submittal identify?Identify product codes, dimensions, mounting conditions, water and soap connections, power, controls, component locations, accessibility coordination and required service access. Why must basin geometry be shown?Spout reach, stream landing, sensor operation, dispenser position and splash control depend on the actual relationship between the fixtures, basin and countertop. What belongs in the commissioning record?Record flushing, leak inspection, power configuration, sensor response, faucet shutoff, soap operation, installed product codes and concealed component locations.

Required Complete Engineering Installation Drawing Package
The engineering package should use consistent component numbering, dimensioning,
symbols and service references across all views. Drawings should coordinate
product geometry, countertop penetrations, plumbing and electrical connections,
sensor coverage, under-counter equipment locations, maintenance access,
accessibility requirements and replaceable components in one unified reference.
Overall Product Dimensions
Shows the principal faucet and soap-dispenser dimensions above the countertop, including overall heights, outlet heights and mounting-base proportions used for architectural and installation coordination.

Engineering note:
This complete engineering sheet is a coordination reference and should not be
scaled. Verify all dimensions, plumbing connections, power requirements,
sensor settings, mounting conditions, service clearances, ADA criteria and
component selections against current Fontana product specifications, approved
project submittals and manufacturer installation instructions before fabrication
or installation.
Architectural, Plumbing & Electrical Coordination Considerations
Countertop Preparation
Coordinate mounting-hole diameters, base locations, deck thickness and sink geometry before drilling or fabricating the countertop.
Water Supply
Provide compatible shut-off valves, mixing components where required and a properly flushed water supply before connecting the faucet system.
Electrical Power
Coordinate the power/control module, faucet sensor, dispenser sensor, solenoid valve and soap pump so wiring remains accessible and protected from moisture.
Sensor Performance
Keep sensor fields clear of reflective surfaces and nearby obstructions and verify both devices after installation for reliable touchless activation.
Under-Counter Service
Maintain sufficient cabinet access for the controller, valves, pump, soap bottle, drain and connection hardware without removing the countertop fixtures.
Accessibility
Coordinate knee clearance, outlet heights, approach space and exposed plumbing protection with the accessibility requirements applicable to the project.
