Operation Checklist
The following checklist should be followed prior to each use of your Freeze Dryer:
1.
Remove the accessory drying chamber or manifold from the connection port
and using a soft, lint-free cloth or paper towel, wipe the port gasket(s) and
sealing surfaces of the drying chamber/manifold and connection port to remove
any dirt or contaminants that could cause a vacuum leak.
2.
Remove the baffle (if equipped) and wipe with a soft cloth or paper towel to
remove any remaining moisture.
3.
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. Insert the quick connect drain fitting into the quick connect drain
coupling located on the front of the Freeze Dryer. If equipped with the Shell
Freezer option, the lower drain coupling is used to drain the collector chamber
and the top is use to drain the Shell Freezer.
Note: Freeze Dryer (Collector or
Vacuum) will not start if moisture is detected in the drain line.
4.
After completely draining the system, disconnect the quick connect drain
fitting from the quick connect drain coupling.
DISCONNECT THE QUICK CONNECT DRAIN FITTING BEFORE
STARTING THE VACUUM PUMP. FAILURE TO REMOVE THE
FITTING WILL RESULT IN A LARGE VACUUM LEAK.
5.
Wipe the interior of the collector chamber with a soft cloth or paper towel to
remove any remaining moisture.
6.
Reinstall baffle (if equipped) in collector chamber.
7.
Reinstall the drying chamber or manifold on the connection port.
Note:
Vacuum grease is NOT required on the drying chamber lid, collector
chamber lid or port gasket(s) to obtain a proper vacuum seal.
8.
Check that each sample valve is closed or in the “vent” position.
9.
Start COLLECTOR and allow the refrigeration system to reach its specified
operating temperature (-50°C or -84°C depending on model)
10.
Start VACUUM when collector temperature is -40°C or colder.
