Heating element temperature settings
To adjust the temperature settings:
1. Turn "off" the electrical power at the junction box
of the water heater.
WARNING
Failure to turn "OFF" electrical power to the
solar water heater will result in the possibility
of property damage, serious injury or loss of
life.
2. Carefully take off the access panel (see page 25).
3. Turn the water temperature dial clockwise to increase
the temperature, or counterclockwise to decrease the
temperature.

4. Carefully replace the access panel.
5. Turn "on" the power supply.
IMPORTANT
Each thermostat is factory preset at "HOT" or
1205°F (493°C). This setting will reduce the risk
of scald injury. This temperature setting has proven
by experience to be the most satisfactory from the
standpoint of operation costs, household needs and the
ability to store solar generated heat.
Solar water heaters installed in Florida require the
thermostat to be set at 125°F (52°C).
