IMPORTANT SAFETY INSTRUCTIONS

READ AND FOLLOW ALL INSTRUCTIONS.

When installing and using this electrical equipment, basic safety precautions should always be followed, including the following:

WARNING : Risk of explosion. For dual steam generator installations, do not interconnect steam outlets. A separate steam line must be provided for each steam outlet.

WARNING : Risk of electrocution. Disconnect all power before performing these installation steps.

WARNING: Risk of personal injury.

• The wet surfaces of steam enclosures may be slippery. Use care when entering or leaving.

• The steam head is hot. Do not touch the steam head and avoid the steam near the steam head.

• Prolonged use of the steam system can excessively raise the internal human body temperature and impair the body’s ability to regulate its internal temperature (hypothermia). Limit your use of steam to 10 – 15 minutes until you are certain of your body’s reaction.

• Excessive temperatures have a high potential for causing fetal damage during the early months of pregnancy.
  Pregnant or possibly pregnant women should consult a physician regarding the correct exposure.

• 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.

• Persons using medication should consult a physician before using a steambath since some medications may induce drowsiness while other medications may effect heart rate, blood pressure, and circulation.

WARNING: The use of alcohol, drugs, or medication can greatly increase the risk of fatal hypothermia.
Prolonged immersion in hot water may induce hypothermia. Hyperthermia occurs when the internal temperature
of the body reaches a level several degrees above the normal body temperature of 98.6°F (37°C). The symptoms of
hypothermia include an increase in the internal temperature of the body, dizziness, lethargy, drowsiness, and
fainting. The effects of hypothermia include: (a) failure to perceive heat, (b) failure to recognise the need to exit the bath, (c) unawareness of impending hazard, (d) fetal damage in pregnant women, (e) physical inability to exit the bath, and (f) unconsciousness resulting in the danger of drowning

WARNING : Risk of personal injury. If you become uncomfortable while taking a steambath, 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, verify that they will not cause an allergic reaction to the user.

CAUTION : Risk of injury. To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.

CAUTION : Risk of personal injury. Do not plumb a trapway in the steam line or plumb the pressure relief valve into the steam line. Plumbing the pressure relief valve into the steam line can be hazardous if the steam outlet is capped.

CAUTION : 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 shortly after shutdown. Wear eye protection and protective clothing when servicing the steam generator. The steam generator operates at high temperatures.

CAUTION: Do not use for space heating purposes.

IMPORTANT! Recommended feed water quality should be: Hardness – less than 60 ppm (3.5 gpg); Total Alkalinity – greater than 150 ppm (8.8 gpg). Calcium scale buildup from hard water can prevent proper operation of the steam generator and may cause premature failure. To verify proper operation, the feed water supply should be tested before operating the steam generator. If feed water quality is not within the specified limit, contact a reputable water treatment company for treatment options.

IMPORTANT! Maximum inlet water pressure is not to exceed 70 psi (483 kPa).

NOTICE : Use this unit only for its intended use as specified in this manual. DO NOT use aĴachments that are not recommended by Kohler Co.

NOTICE : Do not apply excessive heat to the steam generator connections when you solder connections. Do not apply flux or acids directly to the steam generator, as damage to the seals, plastic components, and trim finish may result. Do not apply petroleum-based lubricants to the steam generator components, as damage may result.
