Setting the thermostat:
The water heater is equipped with an adjustable thermostat that once set will automatically control water
temperature. The red indicator lamp remains illuminated while the water is being heated. If the water in
the tank is at the desired temperature the lamp will not be illuminated.
The temperature adjusting knob will increase the temperature by turning the knob clockwise and decrease
the water temperature by turning the knob counter clockwise.
When not being used for a lengthy period of time, you can conserve energy by reducing the water
temperature setting.
Setting the freeze protection:
When the water heater is not being used for an extended period of time and there is a risk of freezing,
either unplug and drain the water heater or turn the thermostat knob to the snowflake position to guard
against freezing. This position will keep the internal water temperature above the freezing point. See
photo below.
Maintenance instructions
Do not attempt to repair this water heater yourself. Call a service person (plumber or electrician) for
service assistance. Always unplug the power supply cord when the water is turned off or when servicing or
draining the water heater.
Before calling for service, first confirm that the water
heater is properly filled and that 110VAC power has not
been interrupted.
