Installation Guide
INDICATOR LIGHT: The light turns on when the heater is operating.
PRESSURE/VACUUM SWITCH: The heater is equipped with a preset pressure or vacuum switch.
The pump must be running with water flowing in the whirlpool to allow the heater to turn on. Note:
Smaller fractional horsepower pumps may not activate the heater. Contact your dealer for
troubleshooting procedure.
1. The heater must be connected only to a supply circuit that is protected by a ground-fault-circuit-
interrupter (GFCI). The GFCI should be tested on a routine basis. To test the GFCI, push the test
button. Power to the bathtub should be turned off. Push the reset button. Power should be
restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts
power to the bathtub without the test button being pushed; a ground current is flowing,
indicating the possibility of an electrical shock. Do not use the bathtub. Disconnect the hydro
massage bathtub and have the problem corrected by a qualified service technician before using.
2. WARNING - Prolonged immersion in hotter water may induce hyperthermia. Hyperthermia occurs
when the internal temperature of the body reaches a level several degrees above the normal body
temperature of 98.6°F. The symptoms of hyperthermia include an increase in the internal
temperature of the body, dizziness, lethargy, drowsiness and fainting. The effects of
hyperthermia include:
A. Failure to perceive heat
B. Failure to recognize the need to exit the bathtub
C. Unawareness of impending hazard
D. Fetal damage in pregnant women
E. Physical inability to exit the bathtub
