Nordmann Engineering AT4 D - Malfunction Lists; System Faults

7.2 Malfunction lists
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 involves a thorough examina-
tion of the entire system. Often, the steam hose connection has not been
properly executed, or the fault lies with the humidity control system.
