Your Kohler Toilet

Your Kohler toilet combines outstanding function, comfort, and
performance with remarkable style and class.

This Kohler toilet was designed to use only 1.4 gallons (5.3 L) or 1.1
(4.2 L) gallons of water for each flush. This ensures that your toilet will
provide exceptional performance that is comparable to our previous 3.5
gallon (13.2 L) models. Your toilet exceeds ASME performance
standards for low-consumption toilets. It was designed with a large,
glazed trapway to keep waste moving without blockage.

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

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.

•

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.

Operation

The vitreous china bowl and tank direct the flushing water flow, and
house the Pressure Lite system.

The vessel contains the complete operating cartridge assembly, and is
the container for the pressurized 1.4 gallons (5.3 L) (FM3 models) or

1.1 gallons (4.2 L) (FM4 models) of water used for each flush.
The control components consist of the pressure regulator and the air

inducer. These components work with the incoming, pressurized,
supply-line water to provide a regulated pressure flush to the toilet
bowl.

A complete flush cycle is two separate functions.
When the trip lever is operated, the vessel plunger assembly is

pressed, allowing pressurized water to be directed to the bowl for
complete flushing action. As the water level in the vessel drops the
plunger will close, stopping water flow to the bowl.

A checkpoint built into the vessel assembly allows any discharge of
water into the vitreous china tank to drain directly into the bowl.

After flushing, a charge cycle takes place. Supply line water flows into

the vessel through the screen and pressure regulator. The water then
flows across the air inducer, which mixes a small amount of air with
the water, filling the vessel until a pressure of approximately 35 psi
(2.5 Kg/cm squared) is reached. The toilet will be ready for the next
flush within 60 to 90 seconds. If the toilet is not ready for the next
flush within that time, please refer to the Troubleshooting section.

Gap Clearance

If the toilet does not activate, the gap between the actuator and
the plunger arm may need to be reset. Make sure the trip lever
handle is installed, and the trip lever nut is tight. This is a
left-hand thread; turn counterclockwise to tighten.

Make sure the water supply is on, and the supply line water has
stopped flowing into the toilet.

Loosen the setscrew. Turn the actuator until there is a 1/16″
(2 mm) - 1/8″ (3 mm) gap between the actuator and the plunger
arm. Turn the actuator clockwise to increase the gap.

Tighten the setscrew after the gap is properly adjusted.

NOTE: Loss of gap clearance adjustment could cause leakage into
the toilet bowl due to the plunger not sealing properly. This
condition could cause a continual flow of water. If the problem is
not corrected after adjustment, refer to the Troubleshooting section.

Winterizing Your Toilet

Turn off the water.
Drain the tank by flushing. Press the actuator down for

approximately one minute to drain the water from the vessel
assembly.

Disconnect the water supply line to the toilet.
Remove the supply shank, and drain the water from the tank.
Press the actuator one more time, then pull the actuator up to

allow air into the vessel.
Add antifreeze to the toilet bowl water to prevent freezing. Use

recreational-type antifreeze commonly used in campers, motor
homes, and boats.

To restart the toilet, first reconnect the water supply line to the
toilet. Then turn on the water supply, and let the system
pressurize for at least one minute.

Check for leaks, and retighten any leaking connections.
