Setup and Installation
Follow these steps carefully for proper installation:
- Prepare the Installation Area:
Ensure the main water supply is turned off. Clear the area around the sink or basin where the faucet will be installed. If replacing an old faucet, remove it and clean the mounting surface.
- Mount the Faucet:
Insert the threaded pipe of the faucet body through the mounting hole on your sink or countertop. Secure the faucet from underneath using the provided mounting hardware (washer and nut). Ensure the faucet is firmly in place and oriented correctly.

- Connect the Control Box:
Mount the control box in a dry, accessible location under the sink, away from direct water spray. Use the provided screws and anchors if necessary. Connect the sensor cable from the faucet to the designated port on the control box. Ensure the connection is secure.

- Connect Water Supply:
Connect the flexible hose from the faucet to the "Water Out" port on the control box. Then, connect your hot and cold water supply lines to the appropriate inlets on the control box. Ensure all connections are tightened securely to prevent leaks. It is recommended to use thread sealant tape on all threaded connections.
- Install Batteries (if using DC power):
Open the battery compartment on the control box and insert 4 AA alkaline batteries, observing the correct polarity. Close the compartment securely. If using AC power, connect the AC adapter (not included) to the control box and a power outlet.
- Test for Leaks and Functionality:
Slowly turn on the main water supply. Check all connections for any signs of leaks. Place your hands within the sensor's detection zone to activate the water flow. Remove your hands to stop the flow. The sensor will automatically adjust its detection distance based on the environment.
Operation
The Ejoyous Automatic Sensor Faucet is designed for simple, touchless operation:
- Automatic Water Flow: To activate water flow, simply place your hands or an object within the detection zone of the infrared sensor, located at the base of the faucet.
- Automatic Shut-off: Water flow will automatically stop once your hands or the object are removed from the sensor's detection zone. This feature helps conserve water and prevents accidental overflow.
- Temperature Control: The faucet includes a hot and cold water mixing valve within the control box, allowing you to set your desired water temperature during installation. Once set, the faucet will dispense water at this pre-set temperature.

Maintenance
Regular maintenance will help prolong the life and maintain the appearance of your Ejoyous Automatic Sensor Faucet:
- Cleaning the Faucet: Clean the chrome surface regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome finishes. Rinse thoroughly with water and dry with a soft cloth to prevent water spots.
- Do Not Use: Avoid using abrasive cleaners, scouring pads, ammonia-based cleaners, or bleach, as these can damage the finish and internal components.
- Sensor Maintenance: Keep the sensor window clean and free from obstructions. Wipe it gently with a soft, damp cloth if it appears dirty.
- Battery Replacement: If the faucet's response becomes sluggish or inconsistent, it may be time to replace the batteries in the control box. Ensure the water supply is off before opening the control box.
- Aerator Cleaning: If water flow becomes weak or uneven, the aerator at the spout may be clogged. Unscrew the aerator, clean any debris, and rinse it before reattaching.
