Toto CST243 Manuel D'installation page 5

NOTE: Three Points of Contact:
The toilet bowl has three points o
contact, which will actually contact the
bottom of the toilet tank when properly
installed. The location of these points
can be seen on the bowl at the tank
receiving area. The three points are front
left (1), front right (2), and back center
(3). Recall these three points during the
Toilet Tank installation.
3) Place the tank upside down onto some
padding. Inspect the smaller fill valve
nut and larger flush valve nut for a
secure connection (see Illustration 4).
Try to tighten the nuts with your hands.
If loose, tighten the nut hand tight and
an additional 1/4 turn for the smaller fill
valve nut and an additional 1/2 turn for
the larger flush valve nut.
Place the tank-to-bowl gasket onto the
flush valve nut. While pressing down,
spread the gasket over the nut until the
gasket touches the bottom of the tank.
A slight gap between the tank bottom
and the gasket is allowable.
4) Lay the tank down on its back. Place a
rubber washer onto a brass bolt (see
Illustration 5). Reach inside the tank
and position the bolt through one of
the holes in the bottom of the tank.
On the outside of the tank, place a
metal washer and nut onto the bolt.
Hold the bolt centered in the hole and
tighten the nut finger tight. Turn the nut
an additional 1/2 turn with a wrench.
Repeat this process for the remaining
hole in the tank.
Pick up the tank and carefully guide
the brass bolts to align the tank with
the bowl. Attach a metal washer and
nut to each bolt. Tighten the nuts finger
tight and inspect that the tank is level
(see Illustration 6). Once level, tighten
the bolts equally until the tank makes
