Setup and Installation
This faucet is designed for a single-hole installation. An optional deck plate is included for installations requiring a wider base or covering additional holes.
- Prepare the Sink: Ensure the mounting surface is clean and dry. If using the optional deck plate, place it over the sink hole(s).
- Install the Faucet: Insert the faucet body through the hole in the sink (and deck plate, if used). Ensure the faucet is oriented correctly.
- Secure the Faucet: From underneath the sink, slide the rubber washer, metal washer, and mounting nut onto the threaded shank. Hand-tighten the mounting nut, then use a basin wrench to fully secure the faucet. Do not overtighten.
- Connect Water Supply Lines: Connect the hot and cold water supply lines from the faucet to your water supply valves. The faucet uses 1/2-inch compression fittings. Ensure connections are tight but do not overtighten.
- Connect Sprayer Hose: Connect the pull-down sprayer hose to the designated port on the faucet's underside. Attach the counterweight to the sprayer hose at the indicated position to ensure smooth retraction.
- Test for Leaks: Turn on the main water supply slowly and check all connections for leaks. Operate the faucet to ensure proper water flow and temperature control.

Maintenance
- Cleaning: Clean the faucet regularly with a soft cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.

- Leak Checks: Periodically inspect all connections for signs of leaks. Tighten any loose connections as needed, but do not overtighten.
