Setup and Installation
Follow these steps to install your new KES faucet head:
- Preparation: Turn off the water supply to your kitchen sink.
- Remove Old Faucet Head: Unscrew your existing pull-down faucet head from the hose. You may need a wrench if it's tightly secured.
- Inspect Hose: Ensure the hose end is clean and free of debris. Check for any existing washers or O-rings that might need to be replaced.
- Install New Faucet Head:
- Ensure the rubber washer is properly seated inside the new faucet head's connector.
- Screw the new KES faucet head onto your existing pull-down hose. Hand-tighten first, then use a wrench for a final quarter-turn to ensure a secure, leak-free connection. Do not overtighten.
- Test for Leaks: Turn the water supply back on slowly. Check for any leaks around the connection point. If leaks occur, tighten slightly more or re-seat the washer.

Operating Instructions
Your KES Kitchen Sink Pull Down Faucet Head features two spray functions for versatile use:
- Aerated Stream: This mode provides a steady, aerated flow of water, ideal for filling pots and general washing.
- Powerful Spray: This mode delivers a strong, wide spray, effective for rinsing dishes and cleaning the sink.
To switch between the two modes, press the button located on the top of the faucet head. The button toggles between the aerated stream and the powerful spray.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your faucet head:
- Cleaning Nozzles: The faucet head features self-cleaning medical TPE nozzles. To clean, gently rub the rubber nozzles with your finger or a soft brush to remove mineral buildup.
- Exterior Cleaning: Clean the exterior of the faucet head with a soft cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the brushed nickel finish.
- Flow Restrictor: The faucet head includes a removable flow restrictor. If you experience reduced water flow, you may check and clean the flow restrictor for any debris. Refer to the diagram for its location.
