Shelf Spacing Adjustment
Prior to loading the shelves with the product to be freeze dried, adjust the shelves
to the 3-shelf, 2-shelf or 1-shelf position. It is best to observe the shelf supporting
mechanism and practice while reading these procedures. In the 3-shelf position,
the spacing between the shelves will accommodate a serum bottle with the stopper
raised up to a maximum height of 75 mm (2.9 inches).
Minimum serum bottle height with lowered stopper for bottles on 3 shelves is 38
mm (1.5 inches).
For a 2-shelf system, grasp the top shelf and raise it until it latches in place. Then
raise the middle shelf approximately 1 inch until it latches in a position to allow a
two equally spaced shelf system. The spacing between shelves will accommodate
a bottle with the stopper raised up to a maximum height of 107 mm (4.2 inches).
Minimum serum bottle height with lowered stopper for a 2-shelf system is 56 mm
(2.2 inches).
For a single shelf system, raise both the top and middle shelves until they latch in
place in their top positions. The spacing for a single shelf system will
accommodate a bottle with raised stopper up to a maximum height of 196 mm
(7.7 inches), and the minimum height of a bottle with lowered stopper for
successful stoppering is 114 mm (4.5 inches).
