After the drying chamber has been loaded, the loading door is closed and
pressed tightly against the flange of the drying chamber with the aid of the
locking handle. The locking handle is now in a perpendicular position with
regard to the door edge (see figure). When a vacuum builds up inside the
drying chamber during the drying process, the loading door will be pulled
closer to the flange of the drying chamber. As a result, the locking handle
will be loosened and it will hang down loosely.
NOTE
If the locking handle does not hang down perpendicularly when the loading
door is closed, it can be readjusted. To do so, loosen the hexagon socket
screw (size 8), readjust the locking handle, and retighten the screw.
WARNING
Do not tighten the door handle when there is a vacuum inside the drying
chamber. During the aeration, the pressure on the locking handle will
increase to such an extent that the loading door may be damaged beyond
repair!

5.7 Manually operated shelf movement
By means of the two push-buttons "Up" (1) and "Down" (2) installed at the
operating panel next to the loading door it is possible to move the shelves
vertically for loading / unloading, stoppering product vials inside the drying
chamber as well as for maintenance purposes. The movement of the
shelves is only possible if the "Up / Down " buttons are pressed
simultaneously (< 0.5 sec) with the push-button "Release" (3) to avoid
injuries ("two-hand control").
