Notes

Install this product according to the installation instructions.

IMPORTANT! Use the supply hoses provided with the fixture. Do not reuse the previously installed hoses.

Installation of a water hammer arrestor is recommended.

Install the docking station cord, when premium remote control is included, before installing the finished wall.

The supplied water inlet hose requires a supply stop with a 1/2" OD compression male outlet thread.

If local codes require the toilet be bolted to the flange, order flange installation kit for required hardware and instructions.

Can be installed with water and electrical supplies attached to the back wall or through the floor. See roughing-in illustration for details.

Adjust the through-the-floor installation as required to meet all local codes.
