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 140°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.
