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 steam generator is operating or

Before You Begin

WARNING: Risk of personal injury. A user interface must
be located within the steam enclosure to allow temperature
regulation and control of the steam flow.

NOTICE: Do not locate the user interface on the same wall as the
steam head(s).

NOTICE: The temperature sensor must be located on the wall
opposite the steam head(s).

If possible install the steam generator(s) and K-99695 system
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.

Locate the temperature sensor on the wall 5″ (127 mm) down
from the ceiling.

Make sure there is adequate clearance between the steam lines
and any surrounding surfaces, or apply appropriate insulation to
the steam lines.

NOTICE: Do not obstruct the steam head with shut-off valves,
plugs, or caps.

Subtract 1-1/4″ (32 mm) from the marked length on the
temporary nipple to determine the appropriate nipple size.

Choose a nipple length within 1/8″ (3 mm) of the appropriate
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.

4. Install the Temperature Sensor

IMPORTANT! Do not locate the temperature sensor directly above
the steam head. Locate the temperature sensor on the wall opposite
the steam head.

IMPORTANT! Make a drip loop in the temperature sensor wire to
prevent moisture from following the wire to the steam generator.

Make sure the power is turned off at the main breaker panel
before proceeding.

Locate the temperature sensor on the wall 5″ (127 mm) down
from the ceiling, on the wall opposite the steam head.

Drill a 3/8″ (K-1737-K1, K-1838-K1) or 7/16″ (K-5548-K1,
K-5549-K1) 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.

INFORMATIONS IMPORTANTES SUR

LA SÉCURITÉ

AVERTISSEMENT: Lors de l’utilisation de cette unité, les
précautions de base doivent toujours être suivies:

DANGER: Risque d’électrocution. Déconnecter

l’alimentation électrique pour la zone de travail au niveau du
disjoncteur principal avant d’exécuter ces étapes
d’installation.

AVERTISSEMENT: Risque de blessures. Si l’on commence à
ressentir une gêne pendant que l’on prend le bain à vapeur,
arrêter l’unité. Se refroidir avec la douche, ouvrir la porte, ou
sortir de l’unité.

AVERTISSEMENT: Risque de réaction allergique. Avant
d’ajouter des huiles, des traitements aromathérapiques ou des
produits de soins de la peau au puits d’aromathérapie,
s’assurer qu’ils ne causeront pas de réaction allergique pour
l’utilisateur.

AVERTISSEMENT: Risque de blessures. Ce bain à vapeur
peut ne pas être approprié pour être utilisé par les femmes
enceintes, les personnes qui ont des problèmes de cœur, une
hypertension artérielle ou des problèmes de circulation, ou
des personnes qui sont sous l’influence d’alcool, qui prennent
des drogues, ou qui sont suivies par un médecin. Un bain à
