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. 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 Ill. 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 Ill. 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.
 C AUTION: Do not move the bowl after the bowl 
wax ring is set. Thread nuts and tighten evenly 
until bowl is snug to closet flange. Install the bolt 
caps.
 C AUTION: 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.
