Fontana FS8014ORB Oil Rubbed Bronze Wall-Mounted Automatic Sensor Faucet: Hot-and-Cold Mixer Configuration

This hot-and-cold mixer configuration resource is intended to support architects, plumbing engineers, electrical engineers, interior designers, contractors, installers and facility managers coordinating a tempered-water installation for the Fontana FS8014ORB wall-mounted automatic sensor faucet. The drawing package identifies the hot-water inlet, cold-water inlet, isolation valves, check valves, thermostatic mixing valve, mixed-water outlet, solenoid valve, flexible faucet supply, temperature-adjustment access and directional flow sequence.

Fontana Oil Rubbed Bronze Wall-Mounted Automatic Sensor Faucet

The Fontana FS8014ORB wall-mounted faucet may be coordinated with a compatible hot-and-cold mixing assembly to provide tempered water at the automatic faucet outlet. Separate hot- and cold-water supplies pass through isolation and check valves before entering the mixing valve. The resulting mixed-water supply continues through the electronically controlled solenoid valve and flexible hose to the wall-mounted faucet.

  • Hot-water inlet: 1/2-inch NPT
  • Cold-water inlet: 1/2-inch NPT
  • Supply isolation: Separate hot- and cold-water valves
  • Backflow control: Hot- and cold-side check valves
  • Mixing component: Thermostatic mixing valve
  • Automatic flow control: Solenoid valve
  • Faucet supply: Flexible mixed-water hose

Required Hot-and-Cold Mixer Configuration Drawing Package

Each drawing should use a consistent line hierarchy, component-numbering system and product-identification block. Hot-water, cold-water and mixed-water paths should be visually distinguishable, and directional arrows should identify the sequence from the building supplies through the mixing and control components to the faucet. Valve sizes, connection designations, temperature-adjustment access and service-clearance requirements should be clearly labeled.

Typical Hot-and-Cold Mixer Configuration

Shows the complete tempered-water arrangement serving the Fontana FS8014ORB automatic sensor faucet. Separate hot- and cold-water supplies enter through isolation and check valves, combine at the thermostatic mixing valve, pass through the solenoid valve and flexible supply hose, and continue to the wall-mounted faucet connection.

Hot-Water Inlet

Identifies the building hot-water connection entering the mixing assembly. The inlet should be clearly marked and routed through an accessible isolation valve and check valve before connecting to the designated hot side of the thermostatic mixing valve.

Cold-Water Inlet

Identifies the building cold-water connection entering the mixing assembly. The cold supply should pass through its own accessible isolation valve and check valve before connecting to the designated cold side of the thermostatic mixing valve.

Isolation Valves

Shows separate service shutoff valves on the hot- and cold-water inlets. The valves allow either supply to be isolated during installation, testing, temperature adjustment, mixer maintenance or component replacement without shutting down unrelated fixtures.

Check Valves

Documents the check valves located downstream of the isolation valves. The check valves are intended to limit reverse flow and cross-connection between the hot- and cold-water branches before the two supplies enter the mixing valve.

Thermostatic Mixing Valve

Identifies the valve that blends the incoming hot and cold water to produce a controlled mixed-water supply. The hot and cold connections, mixed outlet, temperature-adjustment mechanism and service orientation should be shown clearly in the drawing.

Mixed-Water Outlet and Solenoid Valve

Shows the tempered-water path leaving the mixing valve and entering the electrically controlled solenoid valve. The solenoid opens in response to the faucet sensor and control module, allowing mixed water to continue toward the faucet.

Faucet Supply Connection

Identifies the flexible hose connecting the solenoid outlet to the wall-mounted faucet inlet. The hose should be routed without kinks, compression or abrasion, and its fittings should match the designated solenoid and faucet connection sizes.

Temperature-Adjustment Access

Defines the service area required to reach the mixing-valve temperature adjustment. The adjustment cap, screw or control should remain accessible after installation so the outlet temperature can be set, verified and maintained without removing permanent finishes.

Engineering note: The hot-and-cold mixer arrangement shown is a typical coordination configuration. Actual valve-kit components, temperature range, connection sizes, hose lengths and control arrangement may vary according to the selected FontanaShowers package. Verify the mixing valve setting, check-valve orientation, flow direction and connection compatibility against the approved product submittal and installation instructions.

Plumbing, Temperature and Service Coordination Considerations

Hot and Cold Identification

Label the two building supplies clearly and connect each branch to the corresponding hot or cold mixing-valve inlet. Reversed connections can prevent proper temperature control.

Service Isolation

Keep both isolation valves accessible so the hot and cold supplies can be shut off independently during commissioning, adjustment and maintenance.

Check-Valve Orientation

Install each check valve in the indicated direction of flow and provide sufficient access for inspection, cleaning and replacement where required.

Mixing-Valve Access

Locate the thermostatic mixing valve within a serviceable area where maintenance personnel can reach the temperature adjustment, inlet connections and mixed-water outlet.

Outlet-Temperature Verification

Measure the delivered water temperature at the faucet after the system has stabilized. Adjust the mixer in accordance with the approved valve instructions and project temperature requirements.

Flow-Direction Verification

Confirm that the hot, cold and mixed-water arrows correspond with the actual installed piping route from the building supplies to the faucet connection.

Professional Engineering and Accessibility References

Project verification: Hot-and-cold mixer configuration drawings are coordination tools and do not replace approved project submittals. The architect, plumbing engineer, electrical engineer, contractor and licensed installer should verify the hot-water inlet, cold-water inlet, isolation valves, check valves, thermostatic mixing valve, mixed-water outlet, solenoid valve, flexible faucet supply, temperature-adjustment access, flow direction, connection sizes, service access, accessibility requirements and locally adopted codes before installation and commissioning.
