NO TE: Three Points of Contact:

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

3) Place the tank upside down onto some

padding. Inspect the smaller ﬁll valve nut

and larger ﬂush valve nut for a secure con-

nection (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 THREE

POINTS OF CONTACT with the bowl.
