IMPORTANT NOTE:
As you follow these instructions, you will
notice warning and caution symbols. This
blocked information is important for the
safe and ecient installation and opera-
tion of this generator. These are types of
potential hazards that may occur during
this installation and operation:
states a hazard may cause serious injury
or death if precautions are not followed.
signals a situation where minor injury or
product damage may occur if you do not
follow instructions.
IMPORTANT NOTE: This highlights
information that is especially relevant to a
problem-free installation.
All information in these instructions is
based on the latest product information
available at the time of publication.
Sussman-Automatic Corporation reserves
the right to make changes at any time
without notice.
Wheninstallingandusingthiselectricalequipment,basicsafetyprecautions
shouldalwaysbefollowed,includingthefollowing:
IMPORTANTSAFETYINSTRUCTIONS
1. READANDFOLLOWALLINSTRUCTIONS
2. Do not permit children under the age of 16
to use this steambath.
3. To reduce the risk onjury:
A. The wet surfaces of steam enclosures may be slippery. Use care when
entering or leaving.
B. The steam head is hot. Do not touch the steam head and avoid the
steam near the steam head.
C. Prolonged use of the steam system can raise excessively the internal
human body temperature and impair the body’s ability to regulate its
internal temperature (hyperthermia). Limit your use of steam to 10-15
minutes until you are certain of your body’s reaction.
D. Excessive temperatures have a high potential for causing fetal damage
during the early months of pregnancy. Pregnancy or possibly pregnant
women should consult a physician regarding correct exposure.
E. Obese persons and persons with a history of heart disease, low or high
blood pressure, circulatory system problems, or diabetes should consult
a physician before using a steambath.
F. Persons using medication should consult a physician before using a
steambath since some medication may induce drowsiness while other
medications may aect heart rate, blood pressure and circulation.

Steam Room Guidelines
1. Steam room must be completely enclosed, with full
walls, door, oor and ceiling.
2. It is recommended that a gasketed door is used for
steam containment.
3. If tile-type or other smooth surfaced ooring is used
provide suitable anti-skid strips or equivalent, to
prevent a slipping hazard.
4. Check the suitability of any materials with the
manufacturer. Walls and ceilings must be constructed
of water-resistant, non-corrosive surface, such as tile,
marble, molded acrylic, or other non-porous material.
5. The ceiling should be sloped to prevent dripping of
condensate.
6. Provide a oor drain.
7. No heating, venting or air conditioning devices
should be installed inside the steam room.
8. Steam room tile construction information is available
from the Tile Council of America, Inc. by purchasing
the TCA Handbook for Ceramic Tile Installation.
Tel. [phone] or www.tileusa.com.
9. Windows that are part of the steam room should be
double paned and tempered safety glass.
10. Limit steam room ceiling height to 8 feet. Exceeding
8 feet may require a higher-rated steam generator.

To insure proper and automatic safety valve
operation: DO NOT connect a shut off valve or a plug at
safety valve outlet. DO NOT connect a shut off valve or any
construction in steam supply pipe.
Steam Outlet (1⁄2"NPT)
1. Do not install any valve in steam line. Flow of steam must
be unobstructed.
2. Use 1⁄2inch brass pipe or copper tubing from unit to
steam head as permitted by codes.
3. Insulate steam line with fiberglass pipe insulation or similar
insulation rated 212° F or higher.
4. Pitch steam line 1⁄4" per foot towards steam head or steam
generator to avoid valleys and trapping of condensate.
IMPORTANT NOTES:
• Running the steam line down and then up will create a
steam trap blocking the flow of steam.
• A 1.5" hole in the steam room is required to mount the
steamhead.
Water Quality Information
For optimum results, the water supply should be tested prior
to installation. If the mineral content exceeds the following
recommended limits, various external treatment processes are
recommended to correct the problem.
NOTE: An analysis of the on-site water must be made by a
recognized and reliable water treatment company to ascertain
the existing condition and treatment required.
Poor water quality can affect efficiency or result in steam gen-
erator damage. Water contains impurities in solution and sus-
pension. These impurities concentrate in the generator. The
concentration of these impurities increases as more feedwater
is introduced into the generator and steam is produced. If the
suspended solids are allowed to concentrate beyond certain
limits, a deposit or “scale” will form on the generator internal
surfaces.Thisdepositcaninterferewiththepropergenerator
operationandcausegeneratorfailure.Theconcentrationof
theseimpuritiesisgenerallycontrolledbythewaterquality
