1. THEORY OF OPERATION

A. COMPONENTS

Your new Kohler Toilet with its Pressure Lite System

consists of three basic component groups.

•The vitreous china bowl and tank: directs the flushing

water flow and houses the Pressure Lite system.

•The reservoir: contains the complete operating car-

tridge assembly and is the container for the pressurized

1.6 gallons of water used for each flush.

•The control components: consistsof thebackflowpre-

venter,pressureregulator,aspirator,andoutletmanifold.

These components work with the incoming pressurized

supplyline watertoprovide aregulatedpressureflush to

the toilet bowl.

B. FLUSH CYCLE

Your Kohler Lite toilet is designed to flush completely

and efficiently using only 1.6 gallons of water per flush

(gpf) as opposed to non-water saving toilets which can

use up to 7 gallons per flush. Your one-piece toilet also

features the Pressure Lite operating system that uses

incoming water supply line pressure to compress air in

a reservoir within the vitreous china tank.

A complete flush cycle is actually two separate

functions.



1. Whenthetripleveris operated,thereservoir piston

assembly is lifted allowing water under pressure to

be directed to the siphon jet bowl for complete

flushing action. As the water level in the reservoir

drops the piston will close, stopping water flow to

the bowl.

2. After flushing, a charge cycle takes place. Supply

line water flows into the reservoir through the

backflow preventer and pressure regulator; then

acrossthe aspiratorwhichmixes asmallamountof

air with the water, filling the reservoir until a

pressure of approximately 20 p.s.i. 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, refer to the troubleshooting chart.

2. CARE AND CLEANING INSTRUCTIONS

A. CLEANING YOUR VITREOUS CHINA TOILET

CAUTION: Risk of product damage. Do not

use any oil or lubricants on the Pressure Lite

system. This may result in damage to the system.

NOTE: Cleaning of the Pressure Lite system is not

necessary. If cleaning is desired, use only mild soap

and water.

If you live in a hard water area, you should make certain

that the holes in the rim are kept clean for proper bowl

flushing. Toilet bowl cleaners should be used at least

once a week. Use a long-handled brush to clean the rim

holes and to clean as far into the trap as possible to

prevent mineral deposits from forming.

Do not use abrasive cleaners or solvents.

WARNING: Do not use in-tank cleansers.

Products containing chlorine (calcium

hypochlorite) can seriously damage fittings in the

tank. This damage can cause leakage and

property damage.

Kohler Company shall not be responsible or liable for

any damage to these tank fittings caused by the use of

cleansers containing chlorine (calcium hypochlorite).

B. CLEANING YOUR PLASTIC TOILET SEAT

experience freezing temperatures, winterizing the toilet

is recommended.

1. Shut off the water supply. Flush the toilet. Hold the

trip lever down for approximately one minute to

drainthewaterfromthetankassembly.Disconnect

the water supply line.

2. To clean any remaining water from the screen

adapter, backflow preventer, and pressure

regulator, disconnect the supply hose from the

backflow preventer by turning the nut

counterclockwise. Disassemble the screen

adapter, and clean the screen with a medium to

hardbristlebrush.Replacethescreenifnecessary.

After the screen is clean, reassemble in reverse

order making sure the screen is assembled

correctly (see screen detail).

3. Disconnect the outlet tubes from the screen

adapter, backflow preventer, pressure regulator

and aspirator. Snap the backflow preventer,

pressureregulator,andaspiratorassemblyupward

and out of the inlet assembly.

4. Whileholding theaspiratorfirmly, turnthe pressure

regulatorandbackflowpreventercounterclockwise

out of the aspirator. NOTE: Be careful not to drop

the O-ring. Once removed, shake any water from

the backflow preventer and pressure regulator.

5. Replace these assemblies in reverse order making

sure the O-ring is reinstalled between the backflow

preventer, pressure regulator, and aspirator.

6. Add antifreeze to the toilet bowl water to prevent

freezing. Use recreational-type antifreeze

commonly used in campers, motor homes, and

boats.

5. ADJUSTMENT LOCATION AND PROCEDURE

A. ADJUSTMENT

NOTE: Prior to adjustment of actuation arm or trip lever,

always check the reservoir mounting wing nuts on the

bottom of the toilet tank to ensure they are tight.

If the toilet does not activate, the gap between the trip

lever and piston actuation 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 it

counterclockwise to tighten.

Make sure the water supply is on, and the supply line

water has stopped flowing into the toilet.

Turn the piston nut until there is a 1/32” to 1/16” gap

betweenthetrip leverandthepistonactuation arm.Turn

the piston nut clockwise to reduce the gap.

NOTE: Loss of gap clearance adjustment could cause

leakage into the toilet bowl due to the piston not sealing

properly. Thisconditioncouldcausea continuousflowof

water. If the problem is not corrected after adjustment,

refer to the troubleshooting chart.
