o
F, all three phases will be lit.

When water temperature is less than 120
o
F, and set point water temperature is greater than 110
o
F, the lower two phases will
be lit.

When water temperature is less than 110 o F, and set point water temperature is greater than 100 o F, the lowest phase will be lit.

display on this screen.
C. SETTING THE WATER TEMPERATURE
The temperature of the water in the water heater can be regulated by
adjusting the temperature setting up or down using the arrow keys on
the control panel.
Consider safety and energy conservation when selecting the water
heater temperature setting. The lower the temperature setting, the greater the savings in energy and operating costs. To comply with
safety regulations, water temperature is factory set at 120
o F. This is the recommended starting set point.
Water temperatures above 125
o
F can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined in
this manual and on the label located on the water heater near the upper element access panel.
Mixing valves for reducing point-of-use water temperature by mixing hot and cold water in branch water lines are available. Contact a
licensed plumber or the local plumbing authority for further information.
There is a hot water scald potential if the water temperature is set too high. Households with small children, disabled, or elderly persons
may require a 120
o
F or lower thermostat setting to prevent contact with scalding water.
To Adjust the Temperature
First, unlock the key pad by pressing and holding the ENTER key for 3 seconds. Next, press the UP or DOWN arrows on the control
panel key pad to increase or decrease the water temperature. If increasing the water temperature beyond 120
o F, a CAUTION triangle
and thermometer icon will appear on the appliance display to warn the user that raising the water temperature also increases scalding
risk.
