existing toilets, but will not work with all models or variations. The
steps required to install the touchless module to some models of
toilets may differ from those shown.
IMPORTANT! If you experience difficulty installing this product on
your style of toilet, review the compatibility list and installation
videos at KOHLER.com/TouchlessToilet.
NOTE: Most toilets can be configured as touchless flush only
(recommended) or both handle flush and touchless flush. A hole
cover is provided for touchless only configuration.

1. Remove the Handle
Touchless Only Configurations (recommended)
IMPORTANT! Do not install the batteries until instructed. The
sensor will activate when the batteries are installed, making it
difficult to complete the installation process.
NOTE: The steps in this section are recommended, but are optional
for most installations. If your installation will retain the handle, go
to the ″Determine the Bracket Location″section.
Remove the Handle Components
Turn off the water supply to the toilet.
Flush the toilet to remove most of the water from the tank.
Disconnect the chain from the handle.
If the tank has a canister (shown), reattach the chain to itself near
the canister attachment point.
Remove the handle assembly (the nut on the handle assembly
will most likely loosen clockwise).
IMPORTANT! If your model of toilet has a float attached to the
handle chain, the float must not be removed. The float is critical for
proper flushing performance.

2. Determine the Bracket Location
If the water supply was not turned off previously, turn off the
water supply to the toilet.
If there is still water in the tank, flush the toilet to remove most
of the water from the tank.
Close the toilet seat and seat cover to avoid dropping parts in the
bowl.
Remove the tank lid and with the back of the lid toward you
position it upside down on the seat cover or a surface covered
with a towel or other soft material.
Recommended: For tank lid stability, install four pads, two on the
front and two on the back, near each corner of the tank rim
where the lid contacts the tank rim. The pads stabilize the lid,
helping to stop false flushes when the lid is bumped.
Position the module upside down on the right side of the lid,
against the inside of the lid ledge.
Position and hold the bracket on the back ledge as shown.
Note the number of the slot closest to the bottom tab.

3. Position the Module
Flapper Style
NOTE: For most flapper installations, install the module above the
flapper, with the center of the flapper located directly below the
wheel. On some models of toilets, it may be necessary to relocate
the hose to avoid interference with the module.
If the bracket location is on a vent, install the supplied bridge
over the vent.
Position the module with the wheel directly above the center of
the flapper.
Confirm the hose does not interfere with the rotation of the wheel
(manually rotate the wheel). Adjust the position of the hose as
needed.
Canister Style
If the bracket location is over a vent, install the supplied bridge
over the vent to keep the module level.
Locate the module 1″(25 mm) to the side of the canister away
from the fill valve.

4. Adjusting the Module Location
NOTE: To achieve optimal module range and performance, the top
of the module may either lightly contact the bottom of the tank lid
or be within 1/4″(6 mm) of the bottom of the lid. The tank lid and
module can be in contact with each other when the module is
installed, as long as the tank lid sits on the tank correctly when
closed.
Position the tank lid on the tank. Check for fit. Confirm the pads
are correctly installed.
Confirm the module height allows the tank lid to rest in the
correct position.
If the module or bracket interferes with the tank lid, first confirm
the bracket is tight against the rim of the tank.
NOTE: To confirm the tank lid is within 1/4″(6 mm) of the
module, place four quarters on the module. If the tank lid touches
the quarters, the module is within 1/4″(6 mm) of the tank lid.
Confirm the top of the module is within 1/4″(6 mm) or contacts
the bottom of the tank lid.
Adjust the bracket height as needed until the correct module
position is achieved.
Move the tank lid to a safe location when the adjustments are
complete.

5. Connect the Module - Flapper Style
IMPORTANT! For optimal flushing performance, in models where
a float is integrated in the existing handle chain, the float must not
be removed. Use the chain with the float attached. Extend the chain
using the provided chain if needed.
Connect the Module
IMPORTANT! Risk of product damage. Never position the module
with the chain angled from the wheel to a point under the module.
The chain will wrap onto the wheel axel, resulting in continuously
running water and damage to the module.
IMPORTANT! For optimal flushing performance, there must be less
than 1/4″(6 mm) of slack in the chain. The chain must run
vertically or at a slight angle away from the flapper. Flushing
performance will decrease if the chain has too much slack or is at an
extreme angle.
Remove the large clip from the chain supplied with the touchless
kit.

Connect the Module - Flapper Style (cont.)
Determine if the chain attached to the flapper is long enough to
reach to the module wheel attachment point when adding the
large clip. It the existing chain is long enough, attach the large
clip to the chain and wheel.
If the original chain is not long enough, remove the clip on the
original chain.
Connect the small clip on the suppled chain to the end of the
original chain. The attachment point may vary from the model
shown.
Pull the chain tight from the flapper to the wheel. Grasp the chain
link aligned with the connection point on the wheel.
Attach the large clip to the chain link even with the wheel
connection point.
Remove the large clip from the wheel, attach it to the marked
chain link, and reattach the large clip to the wheel.
Confirm Operation
Manually turn the wheel and observe the flapper.
For installations with the handle in place, confirm the handle
chain and module chain do not interfere with each other.
Confirm the chain and wheel do not contact the hose.
Confirm the chain does not wrap on the axle. Adjust the module
position to align the chain closer to vertical if the chain wraps on
the axle.
Confirm the flapper lifts clear of the tank outlet when the chain
connection on the wheel is at the highest point.
Confirm the flapper is fully sealed when the wheel chain
attachment is at its lowest point.
Adjust the clip and add or remove slack if needed.
Remove Extra Chain
Go two chain links past the connection to the large clip and cut
the chain.
NOTE: Leaving more than two chain links hanging below the
wheel connection could result in the chain interfering with the
wheel, causing poor operation or continuously running water.

8. Check Operation
Flush the toilet repeatedly using the module.
Observe the chain and flapper or canister.
Does the flapper/canister lift high enough to flush? If not, adjust
the chain tighter as needed.
IMPORTANT! If the canister spins when flushed, add 1-2 links of
slack to the chain.
Does the flapper/canister fully close when the flush cycle is
complete? If not, adjust the chain to add slack as needed.
Does the canister spin when being raised or lowered during the
flush cycle? If yes, add slack to the chain.
If the handle is still attached, does the chain from the handle
interfere with the flushing action when the touchless flush is
activated? If yes, you may need to disconnect the handle.
Observe the movement of the wheel.
Does the wheel come in contact with anything when rotating?
Adjust the location as needed.
For installations with the handle in place, flush the toilet using
the handle. Confirm the handle chain and module chain do not
interfere with each other.
Turn the water supply back on. Allow the tank to fill.
Confirm operation with a full flush.
