  2. Disconnect the water supply line and remove the old toilet. Clean the flange area thoroughly.
  3. Ensure the floor flange is properly installed and level with the finished floor.
  4. Install the T-bolts into the floor flange.

5.2. Setting the Toilet

  1. Place the wax ring evenly around the discharge opening on the bottom of the toilet.

For easy cleaning, the seat can be quickly removed. Press the quick-release buttons located near the hinges and lift the seat straight up.

7. Maintenance

7.1. Cleaning

  • Clean the toilet regularly with a soft cloth and a mild, non-abrasive cleaner.
  • Avoid using harsh chemicals, abrasive pads, or cleaners containing bleach, as these can damage the finish.
  • For thorough cleaning, remove the quick-release seat as described in Section 6.3.

7.2. General Care
