General Installation Steps (Requires Rough-In Kit)
- Prepare the Installation Area: Ensure the mounting surface is clean and clear. Turn off the water supply.
- Install Rough-In Kit: Follow the instructions provided with your specific Delta rough-in kit to install the control box, power source, and water supply lines. This typically involves mounting the control box under the sink and connecting the hot and cold water lines.
- Mount the Faucet: Place the faucet body through the single hole on the deck. Secure it from underneath with the provided mounting hardware.
- Connect Water Lines: Connect the flexible supply lines from the faucet to the corresponding outlets on the rough-in kit's control box.
- Connect Electronic Cables: Connect the sensor cable from the faucet to the control box. Ensure all electrical connections are secure.
- Test Operation: Turn on the water supply and check for leaks. Activate the sensor to ensure proper water flow.
Operating Instructions
The Delta 590T1151TR faucet operates using an integrated electronic sensor, providing touchless activation for enhanced hygiene.
Sensor Activation
- To Activate Water Flow: Place your hands within the detection range of the sensor located at the base of the faucet spout. Water will begin to flow automatically.
- To Stop Water Flow: Remove your hands from the sensor's detection range. The water flow will cease automatically after a brief delay.
- Adjusting Water Temperature: Water temperature is typically controlled by a mixing valve within the rough-in kit or external thermostatic mixing valve, which is set during installation. This faucet does not have an integrated temperature adjustment handle.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Delta faucet.
Cleaning the Faucet
- Finish Care: Clean the chrome finish with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Sensor Cleaning: Gently wipe the sensor window with a soft, lint-free cloth to ensure it remains clear and responsive. Do not use harsh chemicals on the sensor.
Aerator Maintenance
- Periodically unscrew the aerator from the spout tip and rinse it under running water to remove any debris or mineral buildup. This helps maintain consistent water flow.
- Reinstall the aerator securely, ensuring it is hand-tightened to prevent leaks.
Power Source (Rough-In Kit Dependent)
- If your rough-in kit uses batteries, monitor the battery indicator (if present) or replace batteries as recommended by the rough-in kit's instructions to ensure continuous operation.
- If using an AC adapter, ensure the power connection is secure and free from damage.
