CAUTION
Before adjusting the thermostat, turn off all power supplied to the solar water heater.
The minimum potable water temperature can be changed by adjusting the thermostat. Before any work is done on the water heater, disconnect all power to the water heater and heat source (solar collector) by opening the switch(s) at the main electrical circuit breaker or fuse box. Remove the cover and fold the insulation outward away from the control. Adjust the thermostat dial using a screwdriver until the minimum acceptable temperature is achieved. The thermostat has been factory preset to 120°F (49°C). Remember that lower temperature settings are more energy
efficient. Rotate the temperature dial clockwise to increase water temperature. Rotate the thermostat dial
to decrease the temperature setting. Replace the insulation making sure that the control is well covered and that the plastic terminal shield has not been displaced. Replace the access panel. The water heater is now ready for operation and the main switch can be closed.
