Bradford-White Corp Solar Water Heater manual Maintenance continued

Maintenance continued-

4.Sediment (Annual, but harsh water quality may dictate more frequent service) - Depending on water conditions, a varying amount of sediment may collect in the tank. Levels requiring service are indicated by a small temperature difference in the supply and return lines (See also “Scale” below). Repeated flushing usually clears such material. As a preventive measure, water should be drawn from the tank at the drain valve until it runs clear.

5.Scale (Annual) - Hard water may cause scale to build-up on the outside of the heat exchanger coil. A water softener will prevent this problem (See also “Sediment” above). Symptoms would be reduced recovery capacity or reduced temperature differential between solar collector supply and return lines. Repeated flushing should resolve the problem.

6.Solar Controller -The solar controller manufacturer may have a recommended maintenance procedure. Refer to the installation and operation manual that was received with the solar controller.

7.Solar Collector Panels - The solar collector panel manufacturer may have a recommended maintenance procedure. Refer to the installation and operation manual that was received with the solar collector panels.
