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.
