 WARNING: RISK OF HYPERTHERMIA (OVER-HEATING) 
CAUSING SEVERE INJURY, BURNS, WELTS OR DEATH!
•  Water temperature in excess of 104°F (40°C) may be injurious to 
your health.
•  Refer to Section 3.2 Hyperthermia for specic causes and symptoms 
of this condition.
•  The water in the spa should never exceed 104°F (40°C). Water 
temperatures between 100°F (38°C) and 104°F (40°C) are 
considered safe for a healthy adult.
•  Lower water temperatures are recommended for young children 
(children are especially sensitive to hot water) and when spa use 
may exceed 10 minutes.
•  The Consumer Products Safety Commission/USA has stated that the 
water temperature in a spa should not exceed 104°F (40°C).
•  Always test the spa water temperature before entering the spa. 
The user should measure the water temperature with an accurate 
thermometer since the tolerance of water temperature-regulating 
devices may vary as much as +/- 5°F (2°C).
