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!
