DANGER
Risk of crushing caused by the movement of the loading door
Due to its relative high mass, the movement of the loading door can
hardly be slowed down or stopped.
There is a risk of crushing of body parts between the door and the front of
the chamber.
• Move the loading door slowly holding the door handle when opening or
closing it. Do not hold the door leaf by its edge!
• Lock the door by turning the door handle!
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 below). 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.
CAUTION
Do not tighten the locking 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!
