. We have some really great 'techy' type guys here who are, as they have been exploring the FD mechanics and sharing that in their posts, writing what is turning out to be a 'troubleshooting manual' for us less capable folks.
With the combination of pharmaceutical and food products needing to be more shelf-stable than before, acquiring ideal freeze-drying machinery is crucial.

In addition, the casing stayed in a Secure managing temperature during our lab examination, website even on the best placing.
Reinstalled the vacuum hose and capped far end of hose to do a hose test. (same results as pump alone)
Not all of us are technical experts (the 'not' category includes me) but I hope someone who can help you will come along soon.
Odds are the problem is the vacuum hose or its end connections, the drain valve, or get more info the door gasket. Based upon my experience I'd double check the fittings while installed on the FDer.
