Important! Most operational malfunctions are not caused by faulty equipment but rather by improper
installation or disregarding of planning guidelines. Therefore, a complete fault diagnosis always in-
volves a thorough examination of the entire system. Often, the steam hose connection has not been
properly executed, or the fault lies with the humidity control system.
