Commission, should be observed when using the

spa.

 WARNING

The U.S. Consumer Product Safety Commission

warns that elevated water temperature can be

hazardous. Consult heater operation and installation

instructions for water temperature guidelines before

setting temperature.

1.

Spa or hot tub water temperature should never

exceed 104°F (40°C). One hundred degrees

Fahrenheit (100°F [38°C]) is considered safe for

a healthy adult. Special caution is recommended

for young children.

2.

The 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 take note! 

Soaking in water

above 102°F (38.5°C) can cause fetal damage

during the first three months of pregnancy (which

could result in the birth of a brain-damaged or

deformed child). If pregnant women are going to

use a spa or hot tub, they should make sure the

water temperature is below 100°F (38°C)

maximum.

4.

The water temperature should always be

checked with an accurate thermometer before

entering a spa or hot tub. Temperature controls

may vary by as much as 4F° (2C°).

drowsiness (e.g., tranquilizers, antihistamines, or

anticoagulants) should not use spas or hot tubs.

7.

Prolonged immersion in hot water can induce

hyperthermia.

Hyperthermia occurs when the internal body

temperature reaches a level several degrees above the

normal body temperature of 98.6°F (37°C). Symptoms

include dizziness, fainting, drowsiness, lethargy, and an

increase in the internal body temperature. The effects

of  hyperthermia include:
