Water Heater - How to Adjust Temperature Setpoint

Safety, energy conservation, and hot water capacity are factors to be considered when selecting the water temperature setting of the water heater. Water temperatures above 125° Fahrenheit can cause severe burns or scalding. Be sure to read and follow the warnings outlined on the label located on the water heater near the top of the tank.

Adjusting the Water Heater's Temperature Setpoint

1. Turn off the power to the water heater.
2. Remove the jacket access panel(s) and insulation exposing the thermostat(s). The thermostat protective cover(s) should not be removed.
3. Using a small screwdriver, set the thermostat(s) dial pointer(s) to the desired temperature. Adjust the upper and lower thermostats to the same temperature to maximize hot water availability.
4. Replace the insulation and jacket access panel(s). Turn on the power to the water heater.

For detailed instructions on how to adjust the thermostat(s), refer to the Owner's Manual for the specific model you own.
