BEFORE INSTALLATION
 Read these instructions thoroughly before beginning work.
 Please leave instructions for customers. These instruction contain maintenance
and warranty information.
 If necessary, remove the existing toilet.
INSTALLATION PROCEDURE
In order for your new TOTO® toilet to fit correctly, the distance between the finished
wall to the center of the closet flange must be at 10 to 12 inches. This measurement
is called the Rough-In.
1) Clean any debris out of the closet flange
and then install new mounting bolts
(not supplied) into the slots of the closet
flange (see Illustration 1). The head of the
bolt should be inserted into the slot with
its threads facing upward.
2) Carefully turn the toilet upside down onto
some padding. Firmly press a new bowl
wax ring (not supplied) onto the circular
recess around the toilet bowl’s horn (see
Illustration 2). Turn the toilet upright and
gently lower into position over the closet
flange. With toilet properly aligned, press
firmly on both sides of toilet rim to set the
bowl wax ring (see Illustration 3).
CA UTION: Do not move the bowl after
the bowl wax ring is set. Thread the
nuts and tighten evenly until bowl is
snug to closet flange. Install the bolt
caps (see Illustration 3).
CA UTION: Do not over-tighten the nuts
as damage to the china bowl may
result.

IMPORTANT!
Due to the powerful performance of our Cyclone, G-Max, E-Max and Power Gravity
flushing systems, they are not specified for back-to-back installations. The only
means of installing these toilets in a back-to-back situation is when the toilet drain
connections incorporate a WYE fitting. Please contact your builder or contractor prior
to this installation.
