Section 6: Troubleshooting
Empty Amino
Acid Bottle
Error
Replace the empty bottle with fresh reagent.•
If the bottle is not empty, ensure bottle is securely connected •
to the manifold.
If the bottle is not empty, replace the dip tube lter.•
If the error still occurs, perform a Sensor Calibration (p. 76).•
If the error still occurs, contact CEM Service.•
Empty
Activator,
Activator Base,
or Cleavage
Bottle
Replace the empty bottle with fresh reagent.•
Ensure the bottle is not cracked.•
If the bottle is not empty, ensure bottle is securely connected •
to the manifold.
If the bottle is not empty, replace the dip tube lter.
•
If the error still occurs, perform a Sensor Calibration (p. 76).•
If the error still occurs, contact CEM Service.•
F1/F2
Restriction
Error
Replace the F1 or F2 lter.•
Replace the dip tube lter for the reagent being added.•
If the error still occurs, contact CEM Service.•
F3 Restriction
Error
Replace the F3 lter.•
If the error still occurs, replace the reaction vessel.•
If the error still occurs, contact CEM Service•
Waste Full
Error
Empty the waste container.•
If the waste container is not full, ensure the sensor is not •
engaged (in the up position).
If the error still occurs, contact CEM Service.•
Nitrogen
Pressure Errors
Verify the nitrogen source is functional.•
Verify the pressure setting on the Main Pressure Regulator is •
between 15 and 17 psi.
Perform a Leak Check (p. 88), then contact CEM Service.•
Reaction
Vessel Fails
Leak Check
Verify the tubing connections to the manifold on the front of •
the Liberty are tight and not cross-threaded
Verify the vessel body is tightly connected to the attenuator
•
Verify the PEEK tting on the drain line is tightly connected to •
the bottom of the reaction vessel
Verify the quick disconnect on the drain line is tightly secured•
If the vessel still fails the Leak Check, contact CEM Service•
