IMPORTANT SAFETY PRECAUTIONS (continued)
Consumer Information and Safety
The ThermalFlo series of heat pumps are designed and manufactured to provide many years of safe and reliable service
when installed, operated and maintained according to the information in this manual and the installation codes referred to
in later sections. Throughout the manual, safety warnings and cautions are identified by the “ “ symbol. Be sure to read
and comply with all of the warnings and cautions.
WARNING —The U.S. Consumer Product Safety Commission warns that elevated water temperature can be
hazardous. See below for water temperature guidelines before setting temperature.
WARNING —The following “Safety Rules for Hot Tubs” recommended by the U.S. Consumer Product Safety
Commission should be observed when using the spa.
1. Spa or hot tub water temperatures should never exceed 104° F. [40° C.]. A temperature of 100° F. [38° C.] is considered
safe for a healthy adult. Special caution is suggested for young children. Prolonged immersion in hot water can induce
hyperthermia.
2. Drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to
unconsciousness and subsequently result in drowning.
3. Pregnant women beware! Soaking in water above 100° F. [38° C.] can cause fetal damage during the first three
months of pregnancy (resulting in the birth of a brain-damaged or deformed child). Pregnant women should stick
to the 100° F. [38° C.] maximum rule.
4. Before entering the spa or hot tub, the user should check the water temperature with an accurate thermometer. Spa
or hot tub thermostats may err in regulating water temperatures.
5. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure problems should
obtain their physician's advice before using spas or hot tubs.
6. Persons taking medication which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants should
not use spas or hot tubs.
Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above normal body
temperature of 98.6° F. [37° C.]. The symptoms of hyperthermia include: drowsiness, lethargy, dizziness, fainting, and an
increase in the internal temperature of the body.
The effects of hyperthermia include:
1. Unawareness of impending danger.
2. Failure to perceive heat.
3. Failure to recognize the need to leave the spa.
4. Physical inability to exit the spa.
5. Fetal damage in pregnant women.
6. Unconsciousness resulting in danger of drowning.
