1. Prepare the Installation Area
- Turn off the water supply to the existing toilet and flush to empty the tank.
- Disconnect the water supply line and remove the old toilet.
- Clean the flange area thoroughly and remove any old wax residue.
- Install new closet bolts into the flange channel, ensuring they are securely positioned.
2. Install the Wax Ring and Set the Toilet
- Firmly press the new wax ring onto the bottom of the toilet bowl outlet.
- Carefully align the toilet over the closet bolts and gently lower it onto the flange.
- Apply downward pressure and rock the toilet slightly to ensure a good seal with the wax ring.
3. Secure the Toilet to the Floor
- Place washers and nuts onto the closet bolts.
- Tighten the nuts alternately, a little at a time, to prevent cracking the ceramic. Do not overtighten.
- Install the decorative bolt caps over the nuts.
4. Connect Water Supply and Install Seat
- Connect the flexible water supply line to the toilet's fill valve and the shut-off valve. Hand-tighten first, then use a wrench for a final snug turn.
- Turn on the water supply and check for leaks.
- Allow the tank to fill, then flush the toilet to test operation and check for proper water level. Adjust if necessary.
- Install the toilet seat according to its specific instructions, ensuring it is securely fastened.
Operation
The American Standard Cadet 3 toilet is designed for efficient and quiet operation.
Flushing Mechanism
To flush the toilet, simply press down on the left-hand trip lever located on the side of the tank. The Cadet 3 flushing system utilizes a 2-1/8 inch glazed trap-way and an oversized 3-inch flush valve for a powerful and thorough flush with minimal water usage (1.28 GPF).
Slow-Close Seat

Regular cleaning and maintenance will ensure the longevity and optimal performance of your toilet.
EverClean Surface

General Maintenance
- Periodically check the water supply line for any signs of wear or leaks.
