Toto CST423SF Manuel D'installation page 5

N OTE: The toilet bowl has three points of 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.

4) Place the tank upside down onto some
padding. Inspect the smaller fill valve nut
and larger flush valve nut for a secure con-
nection.
Try to tighten the nuts with your hands see
Ill. 3). 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.
5) Lay the tank down on its back. Place a rub-
ber washer onto a brass bolt. Reach inside
the tank and position the bolt through one
of the holes in the bottom of the tank (see
Ill. 4).
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.
6) 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 Ill. 5). Once level,
tighten the bolts equally until the tank
makes THREE POINTS OF CONTACT with
the bowl.
