Before You Begin
IMPORTANT! When using this unit, basic precautions should always be followed.
DANGER: Risk of electrocution. Disconnect the electricity to the working area at the main breaker
panel before performing these installation steps.
WARNING: Risk of personal injury. If you become uncomfortable while taking a steam bath, you
should power off the unit. Cool off with the shower, open the door, or exit the unit.
WARNING: Risk of allergic reaction. Before adding any oils, aromatic therapies, or skin care
products to the aromatherapy well, make sure they will not cause an allergic reaction to the user.
WARNING: Risk of personal injury. This steam bath may not be suitable for use if you are
pregnant, have a heart condition, have high blood pressure, have circulatory problems, are under
the influence of alcohol, are taking drugs or are under the care of a physician. A steam bath can put
undue stress on the body, as does any hot bath, shower, or sauna.
WARNING: Risk of personal injury. DO NOT consume alcoholic beverages or take
medications/drugs prior to or when using the steam bath. Alcohol and drugs affect mental
judgement and inhibit bodily functions such as heartbeat and respiration, resulting in potentially
dangerous effects.
Silicone Sealant
WARNING: Risk of injury to children. Do not allow children to use this unit unless they are
closely supervised at all times. The steam generator is not designed to be used by children.
WARNING: Risk of scalding. Do not block the steam head or locate it near a seat or bench, as the
steam head is hot during operation and may scald the user if touched.
WARNING: Risk of property damage. Allow a minimum of 12″ (30.5 cm) of air space around the
steam generator at all times. This provides an area for the heat generated by the unit to dissipate.
NOTICE: Use this unit only for its intended use as specified in this manual. DO NOT use attachments not
recommended by Kohler Co.
Follow all local plumbing and electrical codes. All electrical work should be done by a licensed
electrician.
Do not install a GFCI to this unit. This will prevent nuisance tripping.
Disconnect all power before making any electrical connections.
Kohler Co. reserves the right to make revisions in the design of products without notice, as specified
in the Price Book.

WARNING: Risk of scalding. Do not locate the steam head near a seat or bench, as the steam head
is hot during operation and may scald the user if touched.

WARNING: Risk of scalding. Do not locate the steam head near a seat or bench, as the steam head
is hot during operation and may scald the user if touched.
NOTICE: Do not obstruct the steam head with shut-off valves, plugs, or caps.
NOTE: The steam housing can be adjusted for a wall thickness of 3/16″ (5 mm) to 1-1/2″ (3.8 cm) using
the adjustment screws located on the steam head housing.
Position the gasket (provided) around the base of the steam housing so the gasket is between the
wall and the lip of the steam housing.
Turn the adjustment screws on the steam housing until the distance between the back edge of the
steam housing and the head of each adjustment screw is equal to the wall thickness.
Tighten the adjustment screws securely. Do not overtighten.
Secure the steam housing to the wall by carefully tightening the hold-down screws.
Thread the steam head clockwise onto the steam housing assembly until it is hand-tight.

4. Install the Steam Control
NOTICE: Do not locate the control kit directly above the steam outlet.
Make sure that the power is turned off at the main breaker panel before proceeding.
Locate the control pad on the wall 60″ (152.4 cm) up from the floor.
At the selected location, drill a hole 1-1/4″ (3.2 cm) in diameter.
NOTICE: Do not pinch, nail, wedge, or use undue force when handling the control connector and the
control pad wire. Any damage may result in control kit failure. If the control pad is not installed
immediately, protect the control connector with tape or other shielding material.
NOTICE: When installing the control kit, allow room in the control cable for a drip loop. The drip loop
will discourage moisture from following the control cable to the steam generator.
Pull the control connector from the steam generator through the drilled hole.
Carefully plug the control connector to the control pad wire using the double-end female connector
(provided).
Restore the power at the main breaker panel.
Turn on both water and power to the generator.
Test the control pad to ensure it is functioning properly. Refer to the ″Using the Control Pad″
section.
Remove the adhesive backing from the back of the control pad.
Apply a continuous bead of silicone sealant around the back edge of the control pad and around the
perimeter of the adhesive area.
Press the control pad firmly onto the wall.
Apply a bead of silicone sealant around the outside edge of the control pad.
Allow the silicone sealant to cure for 24 hours before use.
