Operation Checklist
The following checklist should be followed prior to each use of your Stoppering
Tray Dryer:
1.
Using a soft, lint-free cloth, wipe the Stoppering Tray Dryer chamber to
remove any moisture or debris. Wipe door gasket to remove any debris or
other contaminants that could cause a vacuum leak. Vacuum grease is NOT
required on the door gasket to obtain a proper vacuum seal.
2.
Remove the collector chamber lid from the Freeze Dryer and ensure that the
collector chamber and drain line are free of water. Place the drain hose in a
suitable container to collect the condensate from the collector chamber and
insert the quick connect drain fitting into the quick connect drain coupling
located on the left hand side of the Freeze Dryer.
Freeze Dryer (Collector or
Vacuum) will not start if moisture is detected in the drain line.
3.
After completely draining the system, disconnect the quick connect drain
fitting from the quick connect drain coupling.
