Original instructions
DISCONNECT THE QUICK CONNECT DRAIN FITTING BEFORE
STARTING THE VACUUM PUMP. FAILURE TO REMOVE THE
FITTING WILL RESULT IN A LARGE VACUUM LEAK.
4.
Wipe the interior of the collector chamber and baffle (if equipped) with a soft
cloth or paper towel to remove any remaining moisture.
5.
Using a soft lint-free cloth wipe the collector chamber lid gasket to remove
any debris or contaminants that could cause a vacuum leak, then install the lid
on the collector chamber. Vacuum grease is NOT required on the collector
chamber lid gasket to obtain a proper vacuum seal.
6.
If the optional 6-Port manifold accessory is installed on your Stoppering Tray
Dryer, make sure that each sample valve is in either the “closed” or “vent”
position.
7.
Start the Freeze Dryer COLLECTOR and allow the refrigeration system to
reach its specified operating temperature (-50°C, -84°C depending on model).
8.
Load samples onto Stoppering Tray Dryer shelves and latch chamber door.
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.
9.
If samples were pre-frozen, Start VACUUM. If the shelves will be used to
freeze the samples, do not start the vacuum until the samples are fully frozen.
10.
Start Stoppering Tray Dryer in either MANUAL or PROGRAM mode to
control the shelf temperature to a set point value.
