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.

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.

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.
