Setting the water temperature to the maximum set point can result in scalding hot water delivered to the faucets. It
is highly recommended that the maximum setpoint be adjusted to the lowest temperature possible for the needs of
the installation. See following section to change the maximum setpoint limit (max setpoint). Make sure the water
heater control display is not in a public area that can result in the temperature settings being improperly adjusted.
See previous warning on scalds and an ASSE approved mixing valve.
