On standard units, the 25° (GREEN) steam nozzle is used for 250°F Wet Steam
operation. This nozzle is sized for operation with the unloader and steam valve
(where applicable) to provide high pressure wet steam. Replacement of this
nozzle with an improperly sized nozzle may cause operational problems with
the machine.
