Abovementioned doors with lock are an effective safety device according to EN ISO 12499: there
is no case where entering during fan operation is required, refer also to chapter 2.2 (Indications
for minimizing specific hazards).
The locking mechanism of the hinged door is on the inside of the door panel and is shown in Fig-
ure 77 (closed position) and Figure 78 (open position). The rolling piston can be pressure from
above (if you are in the unit) with your thumb in the position 'open'.

Readjustment of the door panel position
Because of the handling of AHU sections, the position of the door panel can move (see Figure 79).
Due to the inclination of the door panel of the EU hinged doors, problems can arise when closing
and sealing of the door panel. The door panel can be readjusted through the screws on the hinges.
For this purpose, first the screws on the hinge (Figure 80) must be loosened. Then, the door panel
can be brought in the correct position (Figure 81) and the screws can be tightened again.

If the above described readjustment of the door panel is not sufficient, then unevennesses in the
erection are the cause and must be appropriately corrected.
