1. Theory of Operation
Operating Features
Your Kohler Power-Lite toilet is a one-piece toilet that flushes
completely and efficiently using only a small quantity of water per
flush. The Power-Lite operating system uses an electric, motorized
pump to create a thorough flush.
The Kohler Power-Lite Operating System consists of the following
basic component groups:
The vitreous china bowl and tank, which directs the flushing
water flow and houses the Power-Lite 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 flush button which initiates the flush and refill process.

Theory of Operation (cont.)
Flush Cycle
The flush cycle consists of the following steps:
When either flush button is pressed, an electronic signal is sent to
the circuit board (which is safely housed within the pump).
NOTE: Both flush buttons work the same and produce a full
flushing cycle.
This triggers a timing sequence that turns on the pump motor for
a specific length of time.
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.
2. 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.
114950-5-A 4 Kohler Co.

Safety Features (cont.)
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.
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 Power-Lite 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 Power-Lite
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.
This toilet is available with an optional cover lock that prevents
unauthorized access to the tank and pump. This instruction is
written under the assumption that the cover lock is present. If
this option was not selected, then ignore steps associated with
cover lock operation.
3. Care and Cleaning
NOTE: See the special instructions below before you clean Artist
Edition products.
Clean the outside surface of your vitreous china toilet with mild soap
and warm water. Wipe the entire surface completely dry with a clean,
soft cloth. You may use soft abrasive cleaners when necessary to clean
your toilet. Do not use strong abrasive cleaners, as they will scratch
and dull the surface. Wipe any splashes of cleaner solutions from
plastic or plated surfaces immediately. Use toilet bowl cleaners on the
Kohler Co. 5 114950-5-A

Care and Cleaning (cont.)
inside of the bowl only.
If the surface becomes excessively dirty, use a general purpose cleaner
such as: Fantastik
®
All Purpose, Lysol
®
Basin, Tub and Tile Cleaner,
Soft Scrub
®
Multi Purpose, Scrub Free
®
Disinfectant Bathroom Cleaner,
Clorox Clean-Up
®
, Spic and Span Liquid, Comet
®
Liquid Bathroom
Cleaner, Scrubbing Bubbles
®
Bathroom Cleaner, Bar Keeper’s Friend
®
,
or Bon Ami
®
.
Over time, hard water deposits may clog toilet rim holes and
trapways. To clean, use a commercial cleaner that is recommended for
removing hard water deposits. Follow the cleaner manufacturer’s
instructions.
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 Company shall not be responsible or liable for any tank fitting
damage caused by the use of cleaners containing chlorine (calcium
hypochlorite).
For Artist Edition toilets: Do not use bristle brushes or abrasive
sponges to clean the surface of your Artist Edition toilet. They will
scratch the decorated surface. Gold and Platinum used on decorative
products are like fine jewelry. Use only warm water to clean, and dry
with a soft cloth. Do not let cleaners sit or soak on Artist Edition
surfaces. Rinse and wipe the toilet surface to prevent soap buildup. If
the surface of your Artist Edition toilet becomes excessively dirty, use
Glass Plus
®
or a liquid dish soap with water.

4. Connect Wiring to the Flush Button
CAUTION: Risk of property damage. Ensure that the flush
button plug is completely dry before reconnecting. If it has been
submersed, wipe it down with a dry rag and let it dry.

flush button:
Open the circuit breaker for the toilet.
Using the supplied wrench, turn the locknut in order to release
the hook and remove the tank cover.
