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.

For Installations with a Bidet Seat

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.

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.

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.

Care and Cleaning (cont.)

•Always test your cleaning solution on an inconspicuous area before applying to the entire surface.

•Wipe surfaces clean and rinse completely with water immediately after applying cleaner. Rinse and dry any overspray that lands on nearby surfaces.

•Do not allow cleaners to soak on surfaces.

•Use a soft, dampened sponge or cloth. Never use an abrasive material such as a brush or scouring pad to clean surfaces.

•For Artist Edition Toilets: Treat your decorative product just as you would treat your fine china. DO NOT use bristle brushes or abrasive-backed sponges. They will scratch decorative surfaces.
