Tools and Materials
Before You Begin
IMPORTANT! 2x6 framing is required for this product. 2x4 framing
will not be deep enough to accommodate the carriage assembly.
IMPORTANT! In areas with freezing temperatures, install on an
interior wall. If installed on an exterior wall, provide adequate
insulation to prevent the possibility of freezing.
NOTE: This device is not intended to be used as a retrofit device
for 1.28 gpf (4.8 lpf) water closets.
NOTE: Performance may vary. This product was not tested with
toilets not listed as compatible.
Only bowl numbers K-6299 and K-6300 are compatible with the
carriage.
During installation, make sure the inlet tube connections and
gaskets remain fully engaged to ensure a watertight seal.
Carefully inspect the carriage and tank for damage.
Observe all local plumbing and building codes.

1. Install the Framing
IMPORTANT! This installation requires 2x6 studs. Note the
center-to-center stud dimension is not standard.
IMPORTANT! Note the 3-3/4″(95 mm) dimension from the front
edge of the framing to the center of the outlet pipe. This dimension
is critical for the installation.
NOTE: Refer to the specification sheet for more details and
dimensions for roughing-in.
NOTE: The waste outlet pipe may need to be relocated for this
installation.
NOTE: A PVC elbow is supplied with this product. A cast iron
elbow may be required by codes in some areas. The height of the
toilet drain pipe may need to be adjusted if the cast iron elbow is
used.
NOTE: Double studs must be used on either side of the stud
pocket.
Construct the stud pocket using the dimensions shown.

2. Prepare the Carriage
Raise the Carriage
NOTE: Raise the carriage for ease of installation. It will be lowered
again in a later step.
Position the carriage face down on the floor.
Loosen the nuts securing the legs to the carriage using the
supplied hex wrench.
Raise the carriage 8″(203 mm) - 10″(254 mm) high, enough to
allow room for a wrench and lag bolts over the feet.
Tighten the nuts securing the legs to the carriage.
Install the Electrical Box - Bidet Installations
NOTE: The electrical box is required when the K-4744 bidet seat
will be paired with the bowl. Skip this step for standard
installations.
Connect the electrical box to the carriage at the location shown.

3. Position the Elbow
Position the carriage upright in a secure position.
Gently turn the upper screw (labeled ″Open″) counterclockwise
while applying slight downward pressure on the support strap
until the strap comes free of the locking mechanism.
Move the end of the elbow into place from the front of the
carriage. Rotate the elbow downward as it moves through the
carriage.
With the flared end of the waste pipe against the support strap,
insert the support strap upward into the locking mechanism as
far as possible.
Gently turn the lower locking screw (labeled ″Lock″) clockwise
until you hear a click to secure the waste pipe.

4. Install the Carriage
Move the carriage into place in the stud pocket.
Temporarily secure the carriage in place so it will not fall.
Align the carriage flush with the front edge of the studs. The
front of the carriage should be flush with the front edge of the
studs or set back slightly for finished wall installation.
Check the front of the carriage for plumb.
Mark the hole location for each foot.
Drill a pilot hole (remove the carriage if needed) to reduce the
risk of the lag bolt causing the stud to split or crack.
Secure the feet of the carriage to the studs using 2″(51 mm)
(minimum) lag bolts (not supplied).
Install the threaded rods several turns into the carriage.

5. Adjust the Carriage Height
IMPORTANT! If the carriage is not correctly adjusted, the bowl rim
height may not be compliant with applicable codes. The finished
wall would need to be removed to make the correct adjustments if
the bowl height is not correct.
NOTE: For the K-6299 and K-6300 bowls, the minimum rim height
is 15-5/8″(391 mm) when the finished floor is even with the bottom
of the carriage legs. The maximum rim height is 26″(660 mm) when
the legs are fully raised. The carriage can be adjusted up to 12″(305
mm), with 6″(152 mm) or less of adjustment sufficient in most
installations.
Make a mark 2-5/8″(67 mm) above the top of the threaded rod.
Measure from the top of the finished floor to the mark (A) to
determine the rim height of the bowl.
Loosen the nuts securing the legs to the carriage.
As the carriage is lowered, make sure the elbow aligns with the
toilet drain pipe.

Adjust the Carriage Height (cont.)
If applicable, confirm the gasket on the elbow stays correctly
positioned as it enters the toilet drain pipe.
Adjust the carriage until the desired height is reached. Securely
tighten the nuts using the provided hex wrench to secure the legs
in place.
If a cast iron elbow is required, make the connections following all
applicable codes.
