Before You Begin
CAUTION: Risk of property damage. When connecting
waterless urinals to the building drain waste vent system, do
not use copper pipe or copper tube connectors. The use of a
copper connector will result in corrosion of the connector and
potential building structure damage caused by leakage.
CAUTION: Risk of personal injury. Handle this product
with care. Vitreous china can break or chip if the product is
handled carelessly.
Observe all local plumbing and building codes.
Carefully inspect the new urinal for damage.
Roughing-in remains the same when using the optional 3″ outlet
spud.
Fixture dimensions are nominal and conform to tolerances by

Roughing-In
•
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″ (432 mm) 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 wall hangers as needed.

2. Install the Urinal
CAUTION: Risk of personal injury. Handle with care.
Vitreous china can break or chip if the product is handled
carelessly.
IMPORTANT! Do not overtighten the bolts.
For Retrofit Installations
NOTE: The lip height of the urinal will be 6″ (152 mm) above the
center of the outlet location. If this lip height is not acceptable,
relocate the outlet to achieve an acceptable lip height. The existing
collar may be used with the bracket.
For All Installations
Reference the installation template and position each wall hanger
at the vertical dimension above the outlet hole shown on the
template. To allow for vertical adjustment, place initial screws
through the center of the slots on the wall hangers.
Apply thread sealant tape to the threads on the waste pipe, then
install the collar to the waste pipe.
Center the bracket on top of the collar. Secure two screws through
the slots on the bracket and into the threaded holes on the collar.
With the beveled surface of the gasket facing away from the
collar, seat the gasket firmly against the collar.
Carefully position the urinal on the wall hangers.
