THERMOSTAT Each thermostat is factory preset at 120°F to reduce the risk of scald injury. This setting has proven by experience to be most satisfactory from the standpoint of operational costs and household needs. Solar water heaters installed in Florida require the thermostat(s) to be set at 125°F. If you wish to adjust the settings, see the “Temperature Adjustment” section of this installation manual on page 11. Figure 5 TEMPERATURE REGULATION Flexible metal conduit or flexible metal
