9. Install the Bowl
NOTE: The back of the bowl should touch the wings of the upper
plastic spacer and the plastic connector.
NOTE: If the baseboard molding is thicker than 1/8" (3 mm), it
may need to be cut to allow the bowl to engage the plastic spacer
wings.
Lubricate the top of the connector gasket with silicone plumber's
grease.
Position the toilet over the connector and guide it down onto the
gasket.
Verify that the back of the bowl is flush with the wings of the
upper plastic spacer and the plastic connector.
NOTE: Use the longer screws for the wall, and shorter screws for
the floor.
Install the plastic washers, screws, and caps (provided).
Tighten the bolt cap screws and snap on the low-profile caps.
