INSTALL THE TANK

Carefully turn the tank upside down
onto a protected surface. Fit the rubber
gasket over the flush valve nut.
Carefully position the tank on the bowl
by centering the gasket on the bowl
inlet. Line up the tank and bowl bolt
holes.
The hook, which is outside the front of
the bowl , is for arranging the inlet pipe
and wire of the electronic seat.

Overtightening may

cause breakage or chipping of
the vitreous china.

Install the bolt gaskets onto the tank
bolts, and slide the tank bolts down
through the holes in the tank and bowl.
Assemble the washers and nuts to the
tank bolts. Securely tighten the nuts so
the tank is level.
Be sure the nuts are tight enough to
achieve a watertight seal.

CAUTION: Risk of product
damage.
