Vials not sealing - piston positioning
QUESTION: For those with a Kiel carbonate device, I'm having an issue here that I'm hoping someone out can shed some light on. I have a problem where the piston on line 1 raises the vial to the dropper, but the vial isn't getting retained by the vacuum. I've noticed this happens with the slightly shorter vials. So I'm not sure if it's a potential problem with the vacuum not being strong enough, or a problem with the piston. We've never encountered this kind of problem before. It doesn't happen very often, but enough to be a bit of a pain.
Anyone out there go through the same thing?

ANSWER: The problem is that the piston is not raising the vial high enough. You can adjust the distance the pneumatic cylinder raises the vials. To do this you have to remove the plastic rectangular guide that the lifter cylinders slide through (from inside the oven - 2 screws). Before you remove the guide be sure to mark the position with a scribe or with a fine tipped marker so that you can re-install it in the correct position. Then remove guide piece. Then tell the lifter to go up. You will see that at the bottom of the lifter there is the threaded end of the pneumatic cylinder plunger. On this threaded end is a lock nut and the lifter cylinder. You need to loosen this lock nut while holding the lifter cylinder. You must be careful not to scar the lifter cylinder as it has to slide through the guide block. Once the lock nut is loosened you can unscrew the lifter a little (maybe a half turn). This will raise the lifter a little. Then tighten the lock nut, replace the guide, and all should be well.
Let me know if this helps you. Jason
