If the temperature is warmer than +50°C, the display will show “HI”. If the
temperature is cooler than –50°C, the display will say “LO”.
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).
To unlatch the shelves, press the latch protruding from the side of the shelf
support structure and move the latch until it clears the shelf and allows the shelf to
drop. The top shelf has one latched position, the middle shelf has two latched
positions, and the bottom shelf should not latch in any position.
Shelf Loading
The stoppering mechanism is capable of generating a very strong force, which can
damage the shelves or mechanism. Therefore, it is important to distribute the
serum bottles to be stoppered evenly across the entire surface of each shelf.
Your Stoppering Tray Dryer has a unique system for keeping the shelves level
and moving smoothly while stoppering. If a problem occurs during stoppering,
the system is designed to flex a small amount to lessen the possibility of damage
to the unit.
