5. Installation Guide
Before You Begin:
- Ensure all package contents are present.
- Turn off the main water supply to your kitchen sink.
- Clear the area under the sink for easy access.
- Gather necessary tools (e.g., adjustable wrench, screwdriver, plumber's putty/silicone sealant).
Installation Steps:
- Prepare the Sink Hole: If your sink has multiple holes and you are using the deck plate, ensure it is properly positioned over the holes. For a single-hole installation, the deck plate may not be necessary.
- Mount the Faucet: Insert the faucet body through the center hole of the sink (and deck plate, if used). From underneath the sink, secure the faucet using the provided mounting hardware. Ensure the faucet is oriented correctly before fully tightening.
- Connect Water Supply Lines: Attach the pre-installed hot and cold water supply lines to your home's water supply. The faucet uses 9/16-24 UNEF connections. Ensure connections are tight but do not overtighten.
- Install Counter Weight: Attach the counter weight to the pull-down hose underneath the sink. This weight helps the spray head retract smoothly. Position it to allow full extension of the spray head without obstruction.
- Test for Leaks: Slowly turn on the main water supply. Check all connections for leaks. Operate the faucet to ensure proper hot and cold water flow and spray head functionality.


6. Operating Instructions
Water Flow and Temperature Control:
The faucet features a single lever handle for controlling both water flow and temperature. Lift the handle to increase water flow. Move the handle left for hot water and right for cold water.

Spray Head Functions:
The pull-down spray head offers two distinct water modes: stream and spray. Press the button on the spray head to toggle between these modes.
- Stream Mode: Ideal for filling pots and general washing.
- Spray Mode: Provides a wider, more powerful rinse for cleaning dishes and the sink.


Spout Rotation:
The faucet spout can swivel 360 degrees, providing maximum flexibility and coverage for your sink area. This feature is particularly useful for multi-basin sinks or when needing to move the spout out of the way.

7. Care and Maintenance
Cleaning Instructions:
- To maintain the brushed nickel finish, clean the faucet regularly with a soft, damp cloth.
- Avoid using abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- For stubborn spots, use a mild soap solution and rinse thoroughly with water, then dry with a soft cloth.
Preventative Measures:
- Do not scratch the surface with sharp objects.
- Ensure the faucet is not overtightened during installation to prevent internal damage or deformation.
- Periodically check connections for any signs of leaks and tighten if necessary.
8. Troubleshooting
If you encounter any issues with your RUNFINE kitchen faucet, please refer to the following common problems and solutions:
- Low Water Flow:
Possible Causes: Clogged aerator, partially closed water supply valves, or low water pressure in your home.
Solutions: Unscrew the aerator from the spray head and clean any debris. Ensure both hot and cold water supply valves under the sink are fully open. Check your home's main water pressure. - Leaking from Faucet Base:
Possible Causes: Loose mounting nut, worn O-rings, or improper installation.
Solutions: Ensure the mounting nut under the sink is securely tightened. If the leak persists, the internal O-rings or cartridge may need inspection or replacement by a qualified plumber. - Spray Head Not Retracting:
Possible Causes: Counter weight is obstructed or improperly positioned, or the hose is tangled.
Solutions: Check under the sink to ensure the counter weight is free to move along the hose and is positioned correctly. Untangle any kinks or obstructions in the pull-down hose. - Water Temperature Issues (e.g., only hot or only cold):
Possible Causes: One of the water supply lines is shut off, or the ceramic cartridge is faulty.
Solutions: Verify that both hot and cold water supply valves are fully open. If the problem continues, the ceramic cartridge may require replacement. - Unusual Noise (e.g., whistling, humming):
Possible Causes: Water flow restriction, loose internal components, or air in the lines.
Solutions: Check for any flow reducers in the spray head or supply lines that might be causing turbulence. Ensure all connections are secure. Run water for a few minutes to clear any trapped air.
