Theory of Operation

Operating Features

Your Kohler toilet is a one-piece toilet that flushes completely and efficiently using only a small quantity of water. The operating system uses an electric, motorized pump to create a thorough flush. The long trip button selects a trip time that is adequate for heavy loads. An even shorter flush, and less quantity of water is used when the short trip button is used for light loads.

The operating system consists of the following basic component groups:

The vitreous china bowl and tank, which directs the flushing water flow and houses the system.

The pump, which houses the motor, electronic controls, and impeller.

The fill valve, which refills the tank to the correct water line and sends water to the bowl to establish proper trap seal depth after each flush.

The trip button which initiates the flush and refill process. The selected button determines how much water is flushed through the bowl.

1057478-5-C

Kohler Co.

Theory of Operation (cont.)

Flush Cycle

The flush cycle consists of the following steps:

When either trip button is pressed, an electronic signal is sent to the circuit board (which is safely housed within the pump).

This triggers a timing sequence that turns on the pump motor for a specific length of time. The length of time depends upon which trip button was pressed. The pump runs longer for a long flush.

The pump sends pressurized water to the front jet and rim through the connecting hoses.

This initiates the siphon action in the bowl, and thoroughly flushes the side walls.

As the water in the tank lowers during the pumping action, the fill valve float drops.

This turns on the fill valve to refill the tank.

While the tank is filling, water is also sent through the refill tube to return the bowl to the proper trap seal level.

After the pump turns off, the fill valve continues sending water to both the tank and bowl (through the refill tube).

The fill valve turns off when water reaches the proper water line in the tank.

Safety Features

Your Kohler toilet combines outstanding function, comfort, and performance with remarkable style and class. It contains the following specific safety features:

Your toilet exceeds ASME performance standards for low-consumption toilets.

It was designed with a large glazed trapway to keep waste moving without blockage.

Your Kohler toilet is scratch and abrasion-resistant. It is crafted from a clay mixture that is fired at an intense heat to vitrify the clay and fuse the glaze. Its surface won’t stain, discolor, rust, or fade. Every component in your Kohler toilet is specifically designed to increase the toilet’s useful life.

Safety Features (cont.)

The pump and toilets are listed by Underwriter’s Laboratory (UL) for safety. The fill valve is approved by International Association of Plumbing and Mechanical Officials (IAPMO) for use in this system.

The pump motor and circuit board are sealed in a housing separate from the impeller (which propels the water). The motor turns the impeller by a magnetic coupling. This ensures a separation between the impeller and the motor with electronic controls. There are no gaskets or O-rings that can wear out and allow water to leak into the motor compartment.

Your new toilet is designed to be flushed once every 70 seconds. This feature assures adequate time for the tank to fill with water and provides consistent operation of the motor. However, a second flush can be made 35 seconds after the first flush. If you activate the second flush at this interval, you must wait 105 seconds to activate a third flush. If you attempt a third flush before the 105 seconds have elapsed, the toilet will not flush. This is normal operation.

An overflow slot between the tank and bowl allows water to drain into the bowl and out the trapway if the water level in the tank becomes too high.

Care and Cleaning

WARNING: Risk of property or product damage. Do not use in-tank cleaners in your toilet. Products containing chlorine (calcium hypochlorite) can seriously damage fittings in the tank. This damage can cause leakage and property damage.

Kohler Co. shall not be responsible or liable for any tank fitting damage caused by the use of cleaners containing chlorine (calcium hypochlorite).

For best results, keep the following in mind when caring for your KOHLER product:

•Use a mild detergent such as liquid dishwashing soap and warm water for cleaning. Do not use abrasive cleaners that may scratch or dull the surface.

•Carefully read the cleaner product label to ensure the cleaner is safe for use on the material.

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

Care and Cleaning (cont.)

•Do not allow cleaners to sit or soak on the surface.

•Wipe surfaces clean and rinse completely with water immediately after cleaner application. Rinse and dry any overspray that lands on nearby 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: Gold and Platinum used on decorative products are like fine jewelry. Use only warm water to clean, and dry with a soft cloth.
