INSTALLING TOILET MOUNTING BOLTS
Step 5 CONNECT FLAPPER VALVE CHAIN
Connect hook on end of flapper valve chain to the middle hole of the plastic flush handle rod.
Step 6 WATER LINE CONNECTION
Flush water line briefly to ensure removal of debris. Determine the type of water supply pipe or tubing you have and note assembly parts you will use from the following:
With normal type connection, use cone washer, bevel side up, and compound nut to connect water line to ballcock inlet.
With flange type connection use a flat washer.
DO NOT OVER TIGHTEN NUT.
Step 7 TESTING AND OPERATION 
Turn on water and fill tank.
Adjust ballcock so that water level in tank is at the water level mark. Check for leaks. Tighten nuts slightly if necessary.
Flush tank several times. Check flapper valve for proper operation. If handle is difficult to operate, make sure chain is not tangled.
Clean any construction debris out of the flange, then install the mounting bolts into the side slots of the floor flange. The bolts should be inserted into the slots, bolt heads down, threaded shank pointing upward.
Step 3
BOWL INSTALLATION
Carefully turn the bowl upside down to insert a new wax gasket in the circular recess around the outlet opening.
Turn the bowl upright and gently lower it into position over closet bolts. Align the bowl. With the bowl properly aligned, press down firmly on both sides to set wax gasket.
CAUTION: Do not move the bowl after the wax gasket is set.
Thread nuts onto bolts and hand tighten. Alternately tighten bolts evenly until bowl is snug to flange. Install the bolt caps over bolts.
