Procedure
To troubleshoot possible obstructions in the inlet, do the following:
Step Action
1.
Remove the inlet gasket unit and inspect its condition. If it appears
worn or damaged, replace it.
Rinse the gasket and its openings by filling a syringe with distilled
water and injecting the water through both the syringe and capillary
openings.

•
Fill a syringe with distilled water.
•
Take the end of the inlet tube, press it firmly against the tip of the

freely out of the opening at the end of the probe. If not, replace
the inlet probe and tube.
