THERMOSTAT ADJUSTMENT 160°F Control 180°F Control Figure 16 The thermostat dial is set to its lowest temperature setting when shipped from the factory. Remember that lower temperature settings are more energy efficient. Adjust the temperature by turning the thermostat dial. It is suggested that the starting point setting not be greater than the ” “ or “ “mark on the thermostat dial (approximately 120°F [48.9°C]) as indicated below.
Thermostat Adjusting continued- DANGER Hotter water increases the risk of scald injury. Scalding may occur within five (5) seconds at a temperature setting of 140° F (60° C). To protect against hot water injury, install an ASSE approved mixing valve in the water system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch water lines. A licensed plumbing professional or local plumbing authority should be consulted.
