IMPORTANT SAFETY INSTRUCTIONS 

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

1) READ AND FOLLOW ALL INSTRUCTIONS. 

2) TO REDUCE THE RISK OF INJURY: 

 

a) 

 The water in a pool or tub should never exceed 40°C (104°F). A water temperature more 

 

than 40°C (104°F) is considered unsafe for all persons. Lower water temperatures are 

 

recommended for extended use (exceeding 10-15 minutes) and for young children. 

 

b) 

Excessive water temperatures have a higher potential for causing fetal damage during 

 

the early months of pregnancy, pregnant or possibly pregnant women should limit pool or tub 

 

water temperatures to lower than 38°C (100°F). 

 

c) Before entering a pool or tub, the user should measure the water temperature at several 

 

occupant locations using an accurate thermometer since the tolerance of water temperature-

 

regulating devices may vary as much as ±3°C (±5°F). 

 

d) Alcohol, drugs or medications should not be used before or during pool or tub use since their 

 

use may lead to unconsciousness with the possibility of drowning. 

 

e) Obese persons and persons with a medical history of heart disease, low or high blood 

 

pressure, circulatory system problems, or diabetes should consult a physician before using a pool 

 

or tub. 

 

f) Persons using medication should consult a physician before using a pool or tub since some 

 

medication may induce drowsiness while other medication may affect heart rate, blood pressure 

 

and circulation. 

3) SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE

WARNING 

DANGER OF HYPERTHERMIA 

Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above 
the normal body temperature of 37°C (98.6°F). The symptoms of hyperthermia include dizziness, fainting, 
drowsiness, lethargy and an increase in the internal temperature of the body. The effects of hyperthermia 
include: 

 

a) 

Unawareness of impending hazards; 

 

b) 

Failure to perceive heat; 

 

c)  

Failure to recognize the need to exit pool or tub; 

 

d)  

Physical inability to exit pool or tub; 

 

e) 

Fetal damage in pregnant women; 

 

f) 

Unconsciousness resulting in a danger of drowning. 

WARNING--- The use of alcohol, drugs or medications can greatly increase the risk of fatal hyperthermia 
in pools and tubs.
