WATER LEVEL SENSOR
The bath is equipped with a water level sensor. When the water level is below the sensor, the pump/motor can
not be activated. When the water goes above the level sensor, the pump/motor can then be activated. If the
water level drops below the level sensor, the pump/motor will shut off. To restart the pump/motor after the water
level goes above the level sensor, the ON/OFF button must be pressed.

Operation
Once the heater is installed and the whirlpool pump is operating, the heating function is totally automatic. The
heater will help maintain the temperature of the water in the bath.
Vacuum Switch
The heater is equipped with a preset vacuum switch which will not allow the heater to turn ON if the pump is not
running with water flowing through the whirlpool system.
High-Limit Switch
The heater includes an exclusive High-Limit switch. This safety circuit will not false trip from hot tap water. It will
only turn off the heater if the thermostat fails. To reset, press the button. If the high-limit trips frequently, contact
your dealer.
