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
For your new TOTO toilet to fit correctly, the rough-in, the distance between the finished 
wall to the center of the closet flange, must be at least 12 inches for most models. 
NOTE: Models with 10” rough-in have model numbers ending with “.10”, 
for example C744EF.10.”
 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.
