This document serves as an installation, usage, and maintenance manual for various TOTO toilet models, including one-piece and two-piece configurations. It provides comprehensive instructions in English, Spanish, and French to ensure proper setup, operation, and longevity of the product.

Function Description:

The TOTO toilets described in this manual are designed to provide healthy, hygienic, and comfortable lifestyles. They incorporate advanced flushing systems such as Cyclone, G-Max, E-Max, and Power Gravity, which are engineered for powerful and efficient waste removal. The toilets are primarily intended for residential and commercial use, offering a balance of form and function.

Important Technical Specifications:

Rough-In Dimensions: The manual provides detailed rough-in dimensions for various models, including distances from the finished wall to the center of the toilet outlet ("RI").
- Standard Rough-In: 12 inches (TSU01W.12R / TSU03W.12R / TSU06W.12 - supplied).

Water Supply Location: The water supply should be approximately 8 to 10 inches to the left (facing the bowl) from the centerline of the closet flange and approximately 4-1/2 inches above the floor.
Water Supply Pressure: The static water supply pressure should be between 20 to 80 psi.
Flushing Systems: Cyclone, G-Max, E-Max, and Power Gravity.

Drill Bit Sizes: 11/64" for wood floor installation, 5/16" for concrete/tile installation (for anchors).

Usage Features:

Automatic Water Stop: The fill valve automatically stops the water at the proper level, eliminating the need for ballcock or fill valve adjustments.
Easy Seat Installation: The toilet seat is designed for top-mount installation, with rubber bushing nuts inserted into the bowl seat holes. Fastening is done from the top with a screwdriver.
Fill Valve Adjustment (Type A): For Type A fill valves, the water level can be adjusted by turning a screw clockwise (+) to increase or counter-clockwise (-) to decrease the water level height, referencing the "WL" mark on the inner tank wall.
Fill Valve (Type B): Type B fill valves are preset at the factory and do not require water level adjustments.
Flapper Valve Operation: The manual emphasizes checking the flapper valve for proper operation and ensuring the chain is not tangled.
