Lamp
The water heater is equipped with an
adjustable thermostat that automatically
controls water temperature. The indicator
lamp remains lit only when the water is
being heated.
The temperature is adjusted by turning
the knob clockwise (to the right) to
increase the temperature and counter-
clockwise (to the left) to decrease the
temperature.
The water heater thermostat can be set to
guard against freezing. This position
keeps the internal temperature above the
freezing point.
