Chapter 4: Using Your Freeze Dryer
1. Wipe the interior of the collector chamber with
a soft cloth or paper towel to remove any
accumulated moisture.
2. Check the collector chamber drain hose to
insure that the hose is free of moisture and that
the drain plug is securely installed.
3. Using a soft, lint-free cloth or paper towel,
wipe the collector chamber lid gasket to
remove any dirt and contaminants that could
cause a vacuum leak. Vacuum grease is not
required on the lid gasket to obtain a proper
vacuum seal.
4. 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 and sealing surfaces of the drying
chamber/manifold to remove any dirt and
contaminants that could cause a vacuum leak.
Reinstall the drying chamber or manifold on
the port. Vacuum grease is not required on the
port gasket to obtain a proper vacuum seal.
5. Inspect each sample valve on the drying
chamber or manifold and check for any visible
damage and for improper installation that
might cause a vacuum leak. Also check that
each sample valve is closed or in the “vent”
position.
