• Roughing-in dimensions are identical if using an optional 3"
outlet spud.
• The urinal complies with ADA requirements when the rim is
mounted no higher than 17" (43.2 cm) from the finished floor.

1. Prepare the Site

NOTE: If a pre-existing waste pipe will be used and will result in an
acceptable rim height (refer to the rough-in dimensions), follow the
retrofit installation instructions.
For Retrofit Installations
Turn the water supply line off, remove the existing urinal, then
cap off the water supply line inside the wall.
For New Installations
Install waste pipe as necessary to conform to the roughing-in
dimensions.
Install adequate support framing for the hangers as needed.
