Setup and Installation

Tools You May Need:
- Adjustable Wrench
- Bucket (for catching residual water)
- Towel or Rag
- Flashlight (for under-sink visibility)
Installation Steps:
- Turn Off Water Supply: Locate the hot and cold water shut-off valves under your kitchen sink and turn them clockwise until fully closed.
- Disconnect Old Sprayer:
- Place a bucket under the sink to catch any dripping water.
- Disconnect the hose from the underside of the old sprayer. This usually involves pressing a release tab or unscrewing a nut.
- Carefully pull the old sprayer and hose assembly up through the sink opening.
- Install New Sprayer:
- Feed the new sprayer hose down through the sink opening.
- From underneath the sink, connect the hose to the quick-connect fitting or threaded connection point of your faucet's water line. Ensure a secure connection. For quick-connect fittings, push until you hear a click.
- Position the sprayer head securely in its designated opening on the sink deck.
- Check for Leaks:
- Slowly turn the hot and cold water supply valves back on.
- Check all connections under the sink for any signs of leaks. Tighten connections if necessary.
- Test the sprayer by activating it and observing for leaks around the sprayer head and hose connections.

Maintenance
Regular maintenance will help ensure the longevity and optimal performance of your Moen side sprayer.
Cleaning:
- Clean the chrome finish regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome.

- For mineral deposits on the spray nozzles, gently rub with a soft brush or cloth soaked in a vinegar solution.
Hose Inspection:
- Periodically inspect the sprayer hose under the sink for any signs of wear, kinks, or leaks.
- Ensure the hose moves freely and is not obstructed by other items under the sink.
