INSTALLATION
TO REMOVE EXISTING TOILET
Turn off the water supply. Flush the toilet, and use a
sponge to remove the remaining water from the tank and
bowl. Disconnect the supply shut-off valve (if present),
and remove the old tank and bowl.
Remove the old gasket from the floor and closet flange
with a putty knife. Remove the old T-bolts and discard
them.
NOTICE: If the new toilet is not installed immediately,
temporarily stuff a rag into the closet flange.

TO INSTALL SUPPLY SHUT-OFF VALVE
Install the supply shut-off valve so it is 9” above the
finished floor line. Horizontal placement of the supply
shut-off valve varies depending upon the tank used. For
installations using the K-4620 tank, the supply shut-off
valve must be 5-3/4” to the left of the closet flange
centerline. For installations using the K-4512 tank, the
supplyshut-offvalvemustbe4-1/8”totheleftofthecloset
flange centerline.
The tank model used also affects how far the supply
shut-off valve outlet extends from the finished wall. For
installations using the K-4620 tank, the centerline of the
supply shut-off valve outlet should extend 3-1/8” from the
finished wall. For installations using the K-4512 tank, the
centerlineofthesupplyshut-offvalveoutletshouldextend
3-5/8” from the finished wall. Install the supply shut-off
valve with the outlet vertical.

the holes in the gasket. Set the tank onto the bowl, using
the tank bolts as a guide. Center the gasket on the inlet of
the bowl. Assemble the washers and brass nuts onto the
bolts.
Alternately tighten the three brass nuts so the top of the
tank and the top of the bowl are both level. Be sure the
brass nuts are tight enough to achieve a watertight seal.

Open the supply shut-off valve and check all connections
for leakage. If the connections have been properly
assembled, a slight retightening of the nuts should stop
any leakage.
If the toilet is leaking between the tank and the bowl,
carefully retighten the three brass nuts evenly.
Periodically check all the bowl and tank connections for
leakage for several days following installation.
Install the toilet seat according to the seat manufacturer’s
installation instructions.

water ballast. Adjust the float by sliding it up or down on
the float rod until the water level is at the marked water
line.
Test flush the toilet.
Periodically check all connections for leaks for several
days following installation.
WARNING: Risk of personal injury or property
damage. Do not flush the toilet with the float valve
cap removed. Pressurized water will spray upward,
and may cause injury or water damage.
