Fontana Lymora FS9099BGR Black Granite Automatic Motion Sensor Faucet: Mounting Hardware Detail

This mounting-hardware resource is intended to support countertop fabricators, plumbing contractors, installers, architects and facility personnel coordinating the Fontana Lymora FS9099BGR Black Granite automatic motion-sensor faucet. The drawing package communicates the faucet base, deck gasket, countertop penetration, threaded shank, mounting washer, retaining nut, hose / cable pass-through and typical installation sequence required for a secure, serviceable deck-mounted installation.

Fontana Lymora FS9099BGR Single-Hole Deck-Mount Assembly

The FS9099BGR uses a single-hole countertop installation with a deck gasket, threaded mounting shank, mounting washer and retaining nut. The hot and cold supply hoses together with the sensor / control lead pass below the deck through the mounting area while the faucet base remains centered over the countertop opening.

Required Mounting Hardware Drawing Package

Each mounting drawing should use a consistent countertop datum, faucet centerline and component-identification scheme. The package should clearly identify the deck opening, gasket, faucet base, threaded shank, mounting washer, retaining nut, hose routing, control-lead routing and installation sequence before drilling or final tightening.

Mounting Hardware Detail

Shows the complete deck-mount assembly including the faucet base, deck gasket, countertop opening, threaded shank, mounting washer, retaining nut and hose / cable pass-through.

Enlarged Section — Mounting Hardware

Illustrates how the faucet base sits above the finished countertop while the threaded shank passes through the deck and is secured from below using the washer and retaining nut.

Single-Hole Countertop Opening

Identifies a typical countertop penetration of approximately Ø35 mm (1.38 in.) centered beneath the faucet body. Final opening size should be verified before drilling.

Deck Gasket

Shows the gasket positioned between the faucet base and finished countertop to help create a sealed interface and support even seating of the faucet.

Threaded Shank

Defines the mounting stem passing through the countertop opening. The shank should remain centered so the faucet does not shift during final tightening.

Mounting Washer

Positions the washer against the underside of the countertop to distribute clamping force and stabilize the faucet body.

Retaining Nut

Shows the locknut threaded onto the shank below the washer. Tighten evenly to secure the faucet without over-compressing the gasket or damaging the countertop.

Installation Sequence

Illustrates the typical four-step process: position faucet and gasket, insert shank / hoses / control lead, install washer and retaining nut, then tighten while verifying alignment.

Top View — Base Alignment

Shows the faucet centered over the deck opening with the front sensor window facing the user side. Align the faucet centerline with the basin centerline before final tightening.

Engineering note: All mounting dimensions and component relationships shown are nominal coordination references. Final countertop opening size, deck thickness, gasket configuration, threaded-shank engagement, mounting-hardware sequence, hose routing and tightening requirements should be verified against the approved Fontana Lymora FS9099BGR installation documentation before drilling or final installation.

Installation and Service Coordination Considerations

Countertop Opening

Verify the mounting-hole diameter and centerline before drilling, particularly for stone, quartz, porcelain or other brittle countertop materials.

Gasket Seating

Keep the deck gasket centered and flat beneath the faucet base so it seals evenly and does not bunch during tightening.

Hardware Tightening

Tighten the retaining nut uniformly and avoid over-torquing, which can distort the deck, shift the faucet or damage the mounting assembly.

Faucet Alignment

Align the faucet with the basin centerline and confirm the front sensor window faces the correct direction before final tightening.

Hose & Cable Routing

Route hot and cold hoses and the control lead without twisting, pinching or sharp bends, and maintain enough slack for future service.

Service Access

Keep the under-deck mounting hardware accessible so the faucet can be tightened, removed or serviced without dismantling surrounding cabinetry.

Professional Engineering and Accessibility References

Project verification: Mounting-hardware drawings are coordination tools and do not replace approved product documentation. The architect, plumbing engineer, countertop fabricator, contractor and licensed installer should verify deck opening size, countertop thickness, gasket placement, threaded-shank engagement, washer and nut sequence, faucet alignment, hose / cable routing, service access and locally adopted plumbing requirements before drilling or final installation.
