Problem: The system is not activating
What to do:
1) Confirm that the system is not activating:
 Place your hand on the circulation module or attached pipes. You should feel heat,
feel a slight vibration, and hear a slight hum
 Listen for water flowing inside the drainback tank
2) If the system is not activating:
 Verify temperature difference between the solar collector and tank is greater than 10ºF
 Check that the solar controller is plugged into a working 120VAC outlet and the
circulation module is plugged into the solar controller
 Verify the controller is properly programmed (refer to the solar controller owner’s manual
for programming)
 Verify that the water level in the drainback tank is above the red line on the sightglass
Problem: The system is operating, but not providing enough hot water
What to do:
Increase the temperature setting on the anti-scald valve (if installed)
Flush the filter located inside the circulation module (refer to maintenance section on the
previous page)
For a single tank electric system, verify that the bottom element is activated or solar is providing
sufficient heat when using a large amount of hot water. Refer to the controller owner’s manual
to modify settings.
Ensure that the gas or electric water heater is properly sized and is operating correctly. Refer to
your water heater instruction manual for proper thermostat setting. During cool weather, the
solar system will provide less hot water and rely more on the water heater.
Discuss these options with your FAFCO contractor:
 Add additional solar collectors to increase solar performance
 Install a larger water heater or solar storage tank
Problem: Solar system leaks
