Setup and Installation
Pre-Installation Steps
- Turn off Water Supply: Locate and turn off the hot and cold water supply valves under the sink. If no shut-off valves are present, turn off the main water supply to your home.
- Clear Work Area: Remove any items from under the sink to provide clear access for installation.
- Remove Old Faucet: Disconnect the old faucet's water supply lines and mounting nuts. Carefully lift and remove the old faucet. Clean the sink surface thoroughly.
Faucet Installation
- Install Gasket: Place the rubber gasket (if provided separately) onto the base of the new faucet.
- Position Faucet: Insert the faucet's supply lines and mounting shank through the hole in the sink or countertop. Ensure the faucet is properly oriented.
- Secure Faucet: From underneath the sink, slide the washer and mounting nut onto the mounting shank. Hand-tighten, then use a basin wrench to secure firmly. Do not overtighten.
- Connect Water Lines: Connect the hot and cold supply lines from the faucet to the corresponding shut-off valves. Use a wrench to tighten connections, but avoid overtightening.
- Connect Sprayer Hose: Connect the pull-down sprayer hose to the quick-connect fitting on the main supply line under the sink. Ensure a secure click.
- Install Weight: Attach the hose weight to the pull-down hose at the marked location (typically 6-8 inches from the bottom of the loop) to ensure proper retraction of the sprayer.

Soap Dispenser Installation (if applicable)
- Insert Dispenser: Insert the soap dispenser pump and bottle through the designated hole in the sink or countertop.
- Secure Dispenser: From underneath, thread the mounting nut onto the dispenser shank and tighten securely.
- Fill with Soap: Fill the dispenser bottle with liquid soap from the top.
Operating Instructions
Water Flow and Temperature Control
- Turn On/Off: Lift the single handle to turn on the water flow. Push down to turn off.
- Adjust Temperature: Move the handle to the left for hot water and to the right for cold water.
- Adjust Flow: The height to which the handle is lifted controls the water flow volume.
Pull-Down Sprayer Functionality
- Extend Sprayer: Gently pull the spray wand down from the faucet spout. The hose extends for increased reach.
- MagnaTite Docking: When finished, guide the spray wand back towards the spout. The integrated magnet will securely dock the sprayer in place.
- Spray Modes: The sprayer head typically features buttons or a toggle to switch between different spray patterns (e.g., stream, spray, ShieldSpray).

ShieldSpray Technology
Activate ShieldSpray mode for targeted cleaning. This technology creates a concentrated jet of water surrounded by a protective shield of water, allowing you to power away stubborn messes with minimal splash-back.

Maintenance and Cleaning
General Cleaning
- Clean the faucet regularly with a soft, damp cloth and mild soap.
- Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Wipe the faucet dry after cleaning to prevent water spots.
Touch-Clean Spray Holes
The Touch-Clean soft, rubber spray holes allow for easy removal of mineral build-up. Simply wipe the spray face with your finger or a soft cloth to clear away calcium and lime deposits.
SpotShield Technology (if applicable)
This faucet may feature SpotShield Technology, which helps resist water spots and fingerprints, keeping the faucet cleaner for longer. Regular wiping with a soft cloth is usually sufficient to maintain its appearance.
