below the maximum temperature possible and 1 gpm DIW flow. This will test the
performance of the controller.
a. The unit is allowed to operate with the controller “
Process Temperature Set Point
”
set to a value below the maximum temperature possible and flow set to 1 GPM.
b. If the temperature is not stable, confirm that the controller’s parameters are set to
