Setting the desired temperature for your hot water is a simple task. It is a good idea to turn the circuit breaker off to the water heater before removing the access panels.
You will notice these two covers on the side of the water heater that are held with two screws. After removing the covers you may have to adjust the insulation some to access the temperature settings.
Just turn the little dial with a screwdriver to the desired temperature setting for each element and replace the covers and turn the breaker back on to the water heater.
