Fontana Countertop Faucet & Soap Dispenser: Time-of-Flight Sensor Electrical Connection Diagram

This electrical connection resource is intended to support architects, electrical designers, plumbing engineers, contractors, installers, commissioning personnel and facility managers coordinating the Fontana countertop faucet and automatic soap dispenser within commercial and residential lavatory environments. The diagram identifies the available power options, controller, Time-of-Flight sensor, solenoid valve, soap pump, cable routing and keyed connector arrangements required for system installation.

Fontana Touchless Faucet and Automatic Soap Dispenser with ToF Sensor

This coordinated touchless system uses an electronic controller to process the Time-of-Flight sensor signal and operate the faucet solenoid valve and soap-dispenser pump. Power may be supplied by the recommended 12 VDC AC adapter or by an optional 6 × AA battery pack. The drawing supports connector verification, cable routing, commissioning and under-counter service planning.

FontanaShowers Installation Guide

Required Electrical Connection Drawing Package

Each drawing should use a consistent component numbering system, wire-color convention and connector identification block. The package should clearly distinguish the power input, sensor cable, solenoid-valve cable, soap-pump cable and controller ports. Connector polarity, keyed orientation and service-loop requirements should be documented for installation, commissioning and maintenance.

Electrical System Overview

Shows the complete relationship between the power source, controller, Time-of-Flight sensor, solenoid valve and soap pump. This diagram provides an overall reference for electrical coordination, installation sequencing and project submittals.

Power Options

Identifies the recommended AC adapter and optional battery pack. The AC adapter accepts 100–240 VAC at 50/60 Hz and provides 12 VDC output, while the backup pack uses six AA alkaline batteries to provide 9 VDC.

Controller

Illustrates the central electronic module that receives power, processes the Time-of-Flight sensor signal and controls the connected solenoid valve and soap pump. The controller should remain accessible for inspection and replacement.

Time-of-Flight Sensor Connection

Shows the sensor connected to the controller through the designated ToF sensor cable and keyed connector. The sensor detects user presence and transmits the activation signal to the control module.

Solenoid Valve Connection

Identifies the dedicated solenoid-valve cable and connector. When activated by the controller, the valve opens to permit water flow through the faucet system.

Soap Pump Connection

Identifies the dedicated soap-pump cable and keyed connector. The pump receives the controller output and dispenses soap when the automatic soap-dispenser sensor sequence is activated.

Cable Routing

Defines typical routing for black sensor cables, blue solenoid-valve cables, green soap-pump cables and red/black power conductors. Cables should be supported, protected and kept clear of moisture and moving components.

Connector Identification

Shows the separate power, sensor, solenoid-valve and soap-pump connectors. The connectors are keyed to reduce incorrect assembly and should be fully seated and locked before system energization.

Polarity and Pin Assignment

Summarizes the indicated positive, negative, signal and ground conductors for each connector type. Verify all pin assignments against the approved installation documentation before making connections.

Engineering note: The electrical diagram is a reference document and should not be scaled. Disconnect power before servicing. Use only approved power supplies, controllers, sensors, valves, pumps and cables. Verify connector orientation, polarity, cable routing and environmental protection against the current product specification and installation instructions before energizing the system.

Electrical and Installation Coordination Considerations

Power-Supply Location

Locate the AC adapter or battery pack in a dry, accessible area below the countertop while maintaining suitable clearance from plumbing connections.

Controller Access

Mount the controller where its ports, labels and cable connections remain visible and accessible for commissioning and future service.

Cable Protection

Keep cables away from sharp edges, hot surfaces, moving parts, pinch points and standing moisture. Use suitable clips or ties without over-compressing the cable jackets.

Service Loops

Provide sufficient cable slack for component removal and inspection while preventing loose conductors from contacting valves, drains or cabinet hardware.

Connector Seating

Confirm that every keyed connector is aligned, fully inserted and positively locked before applying power to the controller.

Moisture Separation

Separate electrical components from potential leak paths and provide routing that reduces exposure to water-supply, drain and soap-reservoir connections.

Professional Electrical and Accessibility References

Project verification: Electrical connection diagrams are coordination tools and do not replace approved project submittals. The electrical designer, plumbing engineer, contractor and qualified installer should verify power-source compatibility, controller location, connector assignments, polarity, cable routing, moisture protection, service access, component ratings, applicable electrical codes and manufacturer requirements before installation and energization.
