Tools and Materials
Before You Begin
IMPORTANT! Your product may appear dierent than illustrated. The installation
procedure is the same. Consult the specication sheet for rough-in dimensions for
your model requirements.
Follow all local plumbing and building codes.
Soap Requirements
CAUTION: Risk of product damage. The foaming hand soap must have a
dynamic viscosity rating between 1 centipoise – 100 centipoise (cP) measured
in cP or grams/cm-s units. Soaps with a dynamic viscosity greater than 100 cP
can cause premature wear and damage to the soap dispenser components and
may void the product warranty.

CAUTION: Risk of property damage. Only use liquid foaming hand soap
that contains no suspended particles or microbeads. Do not use non-foaming
liquid hand soaps, which typically have a dynamic viscosity rating of 1000 cP
– 3500 cP.
CAUTION: Risk of product damage. Do not use alcohol-based soap and/or
soaps with alcohol.
NOTE: Kohler foaming hand soaps are precisely formulated to work with this
product and have a dynamic viscosity rating of 1 cP – 20 cP.
NOTE: See kohler.com for more information on recommended foaming hand soaps.
Precise information on soap material properties and dynamic viscosity rating can be

Care and Cleaning
Do not use any abrasive or harsh cleaners to clean the faucets.
For best results, keep the following in mind when caring for your KOHLER product:
Always test your cleaning solution on an inconspicuous area before applying to the
entire surface. Visit kohler.com/clean for KOHLER brand faucet cleaner products.
Wipe surfaces clean and rinse completely with water immediately after applying
cleaner. Rinse and dry any overspray that lands on nearby surfaces.
Do not allow cleaners to soak on surfaces.
Use a soft, dampened sponge or cloth. Never use an abrasive material such as a brush
or scouring pad to clean surfaces.
Upon cleaning other areas of the restroom be sure the sensor lenses are protected
from other cleaning chemicals/solvents to prevent potential damages to the sensor
and/or electronics.
It is recommended to ush the system with warm water every 2 to 3 months.
Remove and clean the nozzle foaming assembly with warm water.
Remove and clean the check valve from the dispensing tube in the soap reservoir
with warm water.
Fill the soap reservoir with minimal amount of clean warm water.
Reaach the soap reservoir to the control box. Press the system prime buon.
Hold the buon down until all of the water has been ushed through the system.
Rell the soap reservoir with the appropriate foaming hand soap. Press and hold
the system prime buon until all residual water is pushed through the pump and
soap is dispensed.
