IMPORTANT INSTRUCTIONS
IMPORTANT SAFETY INFORMATION
WARNING: 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 turn 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, greatly increase the risk of hyperthermia, and
inhibit bodily functions such as heartbeat and respiration,
resulting in potentially dangerous effects.
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 touch the steam head
during operation. The steam head is hot during operation.
WARNING: Risk of personal injury or property damage.
Avoid coming in contact with the water tank and/or steam
discharge line while the generator is operating or shortly

Before You Begin
WARNING: Risk of personal injury. A user interface must
be located within the steam enclosure to allow temperature
regulation and the control of steam flow.
NOTICE: Do not locate the user interface on the same wall as the
steam head(s).

controller before beginning this installation.
Locate the steam head 6″(152 mm) above the floor and 4-1/2″
(114 mm) from the inside of the threshold.
If two steam heads are used, there must be at least 12-1/2″(318
mm) between the center of each hole. The steam heads do not
need to be located in the same area.
Locate the steam head(s) as far away as possible from any shower
seating area.

size.
Apply thread sealant to one end of the nipple and thread into the
housing until hand-tight.
Apply thread sealant to the other end of the nipple.
Position the gasket onto the housing so it will sit between the
finished wall and the housing flange.
Usea1″socket to thread the housing into the elbow.
Make sure the gasket is compressed to achieve a good seal
around the housing.
If needed, use an appropriate sealant to achieve a watertight seal.

from the ceiling.
Drill a 3/8″(10 mm) hole at the selected location.
IMPORTANT! Do not pinch, nail, wedge, or use undue force when
handling the sensor wire. Any damage may result in temperature
sensor failure.
Insert the temperature sensor wire through the drilled hole.
Route the wire behind the wall to the steam generator location.
Apply a small bead of silicone sealant to the back of the sensor
housing. Do not let any sealant contact the sensor probe.
Press the sensor firmly onto the wall.
Temporarily secure the sensor in place with tape.
Allow the silicone sealant to cure before use.
