The Zurn Z831C4-XL is designed for deck-mounted widespread installation on commercial lavatory sinks and counters, with handle centers adjustable from 6" to 20". Professional installation by a licensed plumber is recommended.
Key Installation Requirements:
- Widespread sink or deck with handle centers between 6" and 20"

- Hand-tighten the valve body and mounting nuts. Do not overtighten.
- The aerator may need cleaning at start-up. Unscrew it, clean it and hand-tighten it back in place.

Basic Installation Overview:
- Shut off the water supply to the installation area.
- Set the valve bodies through the sink or deck at the desired centers, and secure them with the included mounting hardware, hand-tight.
- Install the 8" gooseneck spout into the base or diverter tee in the rigid or swing position, then tighten the nut.
- Connect the hot and cold supplies to the 1/2" NPSM coupling nuts.
- Install the wrist blade handles and tighten the handle nuts to 15-20 in-lbs.
