Setup and Installation
This Delta Velum faucet is designed for 1 or 3-hole, 4-inch installations. An optional deck plate with a gasket seal is included to prevent leaks under the faucet.
Tools Required:
- Adjustable Wrench (2x recommended)
- Safety Glasses
- Towel
- Pot or Bucket
- Flashlight (for dark spaces)
- Plumber's Tape (if replacing the drain)
- Silicone (for uneven sink surfaces)
Installation Steps:
- Prepare the Faucet: If using the optional deck plate for a 3-hole installation, feed the PEX supply lines and mounting stud through the center of the escutcheon plate. Ensure the gasket's ridge faces up. For single-hole installations, use the plastic gasket provided, ensuring the ridge faces up.
- Mount the Faucet: Feed the PEX supply lines down through the center hole of your sink. Carefully place the faucet onto the sink, ensuring it is centered. If your sink surface is uneven, apply a thin ring of silicone around the hole before placing the faucet.
- Secure the Faucet: From underneath the sink, secure the faucet to the sink deck using the provided bracket. Ensure the bumps on the bracket face up and the curved side faces the back wall. Use the included wrench to tighten the nut onto the mounting stud.
- Connect Supply Lines: Connect the color-coded PEX supply lines (red for hot, blue for cold) to your stub-outs. Hand-tighten first, then use an adjustable wrench for one 360-degree rotation to ensure a secure, leak-free connection.
- Flush the Faucet: Before final use, flush the lines to remove any debris. Remove the aerator cartridge from the spout using the included aerator wrench. Turn on the water to a full mixed position (equal hot and cold) for about 30 seconds. Use a washcloth to manage splashing. Reinstall the aerator cartridge.
- Check for Leaks: After flushing and reassembling, thoroughly check all connections and the faucet base for any leaks.

Operating Instructions
Faucet Operation:
The Delta Velum faucet features a single handle for controlling both water temperature and flow. Lift the handle to turn on the water and push it down to turn it off. Move the handle left for hot water and right for cold water. Adjust the handle position to achieve your desired temperature and flow rate.
Push-Pop Drain Operation:
The included metal push-pop drain assembly allows for easy opening and closing of the drain. Simply press down on the drain stopper to close it and retain water in the sink. Press down again to open the drain and allow water to flow out.
Maintenance
Cleaning:
To maintain the finish of your Delta faucet, clean it regularly with a soft, damp cloth. Avoid using abrasive cleaners, harsh chemicals, or polishes, as these can damage the finish. For stubborn spots, a mild soap and water solution can be used, followed by rinsing and drying.
DIAMOND Seal Technology:
Your Delta faucet is equipped with patented DIAMOND Seal Technology, which uses a tough diamond-embedded ceramic disc. This technology eliminates wear on seals, ensuring leak-free operation for the life of the faucet and lasting twice as long as the industry standard. InnoFlex PEX supply lines are integrated into the faucet for one less leak point and are made to resist cracks, kinks, and corrosion.
