REMOVE OLD TOILET
1. Turn off the water supply, then flush to empty tank. Use a
sponge & basin to soak up any water left in the tank or bowl. 2.
Disconnect the supply line from the toilet tank. 3. Disassemble
tank from bowl by removing lock nuts from the underside of the
tank. 4. Pry off the bolt caps, remove nuts that secure the toilet to
the floor. Use a rocking motion to remove the old toilet from the
floor. 5. Scrape the old wax gasket from the floor flange.
INSTALL YOUR NEW TOILET
1. Before installing a new wax ring gasket, TEMPORARILY install
flange T-bolts, set toilet on floor, and place discs and nuts onto
bolts. Mark bolt length needed for bolt cap clearance. Remove
bolts from toilet and cut the bolts to
length with hacksaw. 2. Carefully
turn the toilet bowl upside down
onto a thick layer of newspaper or
dropcloth to protect the finish.
Place a new wax gasket on toilet
outlet. A bead of setting compound
may be applied to the base/foot
if desired. 3. Install the two
pre-cut T-bolts in the floor flange.
SET THE BOWL
1. Carefully lower toilet so the T-bolts will protrude through holes
in bowl base. (May require help to align). 2. Apply full body
weight to rim of bowl for proper gasket seal. 3. Place discs (bevel
side up) and nuts onto T-bolts and tighten nuts. DO NOT
OVERTIGHTEN as breaking or chipping of china may result.
WARNING: Breaking or chipping of china may result in
physical injury. 4. Press bolt caps onto discs.
ASSEMBLE TANK TO BOWL
1. With the tank upside down, press the tank to bowl gasket firmly
around the flush valve locknut. Turn tank upright. 2. Slip rubber
washers over the two tank bolts. Insert the bolts through the holes
in the bottom of the tank. 3. Lower tank onto bowl, carefully aligning
the tank bolts with the holes in the bowl. Set tank in place. From
beneath the bowl, assemble the metal washers and nuts onto
the tank bolts. 4. Push down on side (A) of tank and finger-tighten
the nut. Do the same for side (B) of tank. 5. Place a level across
top of tank. Make necessary tightening adjustments to level tank.
Tighten nuts evenly. STOP when china tank comes in contact with
the front and back sanitary bars on bowl shelf. DO NOT
OVERTIGHTEN as breaking or chipping of china may result.
CONNECT WATER SUPPLY
1. Before connecting the water supply, flush the line into a
bucket to remove any debris. 2. Place the coupling nut, friction
washer and universal washer onto the plain end of supply
tube as shown. NOTE: The same universal washer will be
used to make the flanged slipjoint
connection for a 1/2" O.D. or
3/8" flexible, or a 3/8" I.P.S. supply.
3. Temporarily make fingertight
connection to tank supply
shank. Mark at shut-off valve
the tube length needed and
add 1/4". (This will insert down
into shut-off valve). 4. Remove
supply tube and cut to length
including the extra 1/4".
Remove any burrs from inside
the cut end. Slip compression
nut and ring (ferrule) onto the
shut-off valve end of the tubing.
5. Connect supply tube to supply shank once more and
finger-tighten.Tubing may be pushed up into tank supply to
allow the extra 1/4" to be inserted into shut-off valve. 6.
Tighten both the coupling nut at the tank and the compression
nut at the shut-off valve. Make sure float valve does not rotate
while tightening the coupling nut. The float cup must be free
from contact with the tank walls in order to flush properly. 7.
Turn on water supply and shut-off valve. Check for leaks. An
additional tightening adjustments on leaking connections will
normally stop the leak.
ATTACH TOILET SEAT
Attach the toilet seat to the toilet bowl according to the
manufacturer’s installation instructions. If using an extra heavy-
duty plastic seat, install a seat with the self-sustaining
feature and check hinges to avoid damage to rim of bowl
from slamming of seat onto china.
