IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS.
IMPORTANT! 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.
CAUTION: Risk of electrocution. Disconnect the electricity to the working area at the main breaker panel before performing these installation steps.
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.
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 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.
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 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 affect heart rate, blood pressure and circulation.
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 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 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.
CAUTION: Risk of personal injury. Do not plumb a trap 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! 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 hyperthermia include an increase in the internal temperature of the body, dizziness, lethargy, drowsiness, and fainting. The effects of hyperthermia include:
Failure to perceive heat
Failure to recognize the need to exit the steambath
