Setup (Installation Steps)
Follow these steps for proper installation:
- Prepare the Mounting Hole: If replacing an old faucet, remove it. Clean the mounting surface. If your sink has multiple holes, use the included deck plate to cover unused holes.
- Install the Faucet Body: Insert the main faucet body into the mounting hole from above the sink. Ensure the rubber gasket is correctly positioned between the faucet base and the sink surface.
- Secure the Faucet: From underneath the sink, slide the metal washer and mounting nut onto the threaded shank of the faucet. Tighten the nut securely using a basin wrench, ensuring the faucet is aligned correctly.
- Connect Water Supply Lines:
- Connect the hot water supply hose (red marking) to your hot water stop valve.
- Connect the cold water supply hose (blue marking) to your cold water stop valve.
- Connect the filtered water supply line to your RO system's output using the quick fitting.
- Install the Pull-Down Hose Weight: Attach the weight to the pull-down sprayer hose, typically about 6-8 inches from the bottom of the faucet body, to ensure smooth retraction.
- Test for Leaks: Turn on the main water supply slowly and check all connections for leaks. Operate the faucet in all modes to ensure proper function.

Operating Instructions
Your APPASO Kitchen Faucet offers versatile water delivery options:
- Standard Hot & Cold Water: Use the main handle on the right to control water flow and temperature. Lift the handle for water, move left for hot, and right for cold.
- Filtered (RO) Water: Use the smaller handle on the left to activate the filtered water flow. This water is delivered through a separate internal channel and spout.
- Pull-Down Sprayer Functions:
- Pull down the sprayer head from the main spout.
- Press the button on the sprayer head to switch between Stream (aerated flow) and Spray (powerful rinse) modes.
- Some models may include a pause button to temporarily stop water flow directly from the sprayer.
- 360° Swivel: The main spout and the filtered water spout can rotate 360 degrees independently, providing maximum flexibility.

Maintenance
Proper care will ensure the longevity and appearance of your faucet:
- Regular 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 matte black finish.
- Aerator Maintenance: If water flow decreases or becomes irregular, unscrew the aerator from the tip of the spout and clean any mineral deposits or debris. Rinse thoroughly and reattach.
- Drip-Free Valve: The ceramic disc valve is designed for long-term, drip-free performance. If a drip occurs, contact customer support for assistance.
- Hose Care: Ensure the pull-down hose moves freely and is not obstructed by items under the sink.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Clogged aerator; partially closed stop valve; debris in supply line. | Clean aerator; fully open stop valves; flush supply lines. |
| Leaking from Spout | Worn ceramic cartridge; loose connections. | Ensure connections are tight; contact support for cartridge replacement. |
| Sprayer Not Retracting | Weight on hose is misplaced or obstructed. | Adjust the hose weight position; clear any obstructions under the sink. |
| Filtered Water Not Flowing | RO system issues; filtered water stop valve closed. | Check your RO system; ensure filtered water stop valve is open. |
