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 collector chamber
lid and using a soft, lint-free cloth or paper towel, wipe the port gasket(s) and
sealing surfaces of the drying chamber/manifold and collector chamber lid to
remove any dirt or contaminants that could cause a vacuum leak.
2.
Remove 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 left hand side of the Freeze Dryer.
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 collector chamber lid.
Note:
Vacuum grease is NOT required on the drying or collector chamber lid
gasket 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, -84°C, or -105°C depending on model)
10.
Start VACUUM when collector temperature is -40°C or colder.
