If the system fails to operate, check the following:
1.Check water temperature. Systems will turn on between 40° and 45°F and turn off above 45°F.
2.Check water level. Water must completely cover the sensor probe.
3.Make sure the sensor is not encased in ice. See Deicing procedure.
The following checks should be made by a qualified electrician.
4.Remove panel cover and check incoming electrical power for proper voltage. Make sure all phases are present. Correct as required.
