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:  Unawareness of impending danger.  Failure to perceive heat.  Failure to recognize the need to leave the spa.  Physical inability to exit the spa.  Fetal damage in pregnant women.  Unconsciousness resulting in danger of drowning.

Pounds per square inch (PSI) is typically used with water "pressure", "suction" or system measurements. Inches of Water (inwc) is typically used with gas or air pressure measurements (1.0 inHg = .49 PSI = 13.5inwc) 10 USE ONLY GENUINE REPLACEMENT PARTS
