Tools and Materials
Before You Begin
CAUTION: Risk of back injury. Because the tank is already
installed, making the toilet heavy and awkward, two people
should move the toilet into place.
IMPORTANT! This product should be installed by an experienced
installer.
IMPORTANT! Two people are required to lift this toilet into place,
as the tank must be installed prior to moving the toilet into the final
installation location.
IMPORTANT! This product is designed to be installed directly to 4″
D. waste tubing. It is not designed to use a floor flange. Special
installation measures may need to be taken if there is a floor flange
in place, including removing the floor flange or grinding it to allow
for proper fit.
IMPORTANT! For ease of installation, this toilet should be installed
to a waste outlet constructed from PVC.
This toilet does not install to a typical flange. It is designed to
install directly to PVC outlets only. No flange is needed.

2. Mark the Installation
Remove the gasket from the waste tube.
Tilt the toilet, attach the 4″D. waste tube, and move the toilet
into the installation position. The waste tube and waste outlet
should be engaged.
IMPORTANT! If there is a flange and the floor flange sits above the
finished floor, check for proper fit with the base of the toilet. If the
base of the toilet does not fit over the floor flange you will need to
cut or grind (depending upon the flange material) the flange to
allow the toilet to install properly.
Make sure there is a 1″(2.5 cm) gap between the back of the toilet
and the wall.
IMPORTANT! Make sure the toilet is correctly positioned before
marking installation location.
Trace the base of the bowl on the floor.
Remove the waste tube and toilet, and set aside.
Cut the template along the outside line with a scissors.

Mark the Installation (cont.)
Lay the template on the mounting location, matching the outside
edge with the line on the floor.
If there is a flange and the holes marked on the template overlap
the flange, you will need to either cut or grind (depending on the
flange material) the flange until the holes can be drilled into the
subfloor
Use masking tape to hold the template in place.
Drill two 9/16″holes, 1-1/2″(3.8 cm) deep minimum, at the
locations marked on the template.

3. Install the Toilet
CAUTION: Risk of back injury. Because the tank is already
installed, making the toilet heavy and awkward, two people
should move the toilet into place.
Reinstall the gasket to the waste tube.
Tilt the toilet to one side and install the waste tube.
Position a support block under each side of the toilet to raise the
base 3″(7.6 cm) off the floor. The blocks should be positioned so
the supply hose can reach the supply when the toilet rests on
them.
Wet the gasket thoroughly with soapy water or O-ring lubricant.
Insert the provided foam block into the gap between the waste
tube and the surface above it. This will provide support to keep
the waste tube from shifting while inserting the waste tube into
the waste outlet.
Connect the supply hose to the supply stop.

Install the Toilet (cont.)
Turn the water on (There is shut-off valve in the toilet tank that
should already be in the closed position. Turn it off if the tank
begins to fill) and check for leaks.
With a partner, carefully lift the toilet up and remove the support
blocks.
Hold the toilet over the waste outlet and carefully lower it into
place, making sure the waste tube slides into the waste outlet.
IMPORTANT! If the waste outlet and waste tube are not properly
aligned, the waste tube may shift, resulting in leaks.
Check the toilet for proper operation.

4. Install the Floor Bolts
Make sure the plastic anchor on the end of the bolt is relaxed and
not expanded.
Carefully run the bolt through one of the seat holes near the basin
of the toilet.
When the end of the bolt is properly positioned, the top of the
bolt will seat firmly in the hole, slightly below the level of the
toilet. If the bolt sits higher than the toilet, it is not properly
seated in the floor.
Repeat with the second bolt.
Using the provided hex wrench, evenly tighten each bolt until the
toilet is firmly held in place (confirm by trying to rock the toilet).
