Temperature Adjustment Potentiometer - (L) and (S) Activation Models
The potentiometer allows the factory preset temperature of the heater to be changed in the field. The
potentiometer will adjust water temperature between 70°F and 125°F provided the wattage of the heater selected
is capable of producing the temperature increase at the requested flow rate. See Table 3 temperature chart for
each model to determine the temperature range of the heater installed.
When using the potentiometer please use the following operation instructions:
To increase temperature:
a. Loosen nut
b. Using a screwdriver, turn screw in small increments clockwise (to the right)
c. Once temperature of the water is acquired, tighten the nut
To decrease water temperature:
a. Loosen nut
b. Using a screwdriver, turn screw in small increments counter clockwise (to the left)
c. Once temperature is acquired, tighten the nut
Temperature Adjustment - (H) Activation Models
The H model is factory preset for 84°F only and is designed for tepid water use. See Table 3 temperature chart for
each model to determine the temperature range of the heater installed.
