After putting on silicone glue at the wires, one video says to run the vacuum pump for 24 hours, another says 15-20 minutes, while yet another says “until pressure has bottomed out.” Which is it?

To seal the epoxy, you should first remove the panels and run the vacuum for at least 24 hours after applying 100% silicone around the wires. This allows the silicone to properly cure and ensure a good seal. You can find the correct instructions in our most up-to-date video on sealing the epoxy, which is available here:

The 15-20 minutes mentioned in another video might be referring to a different part of the process, possibly the vacuum test. In the vacuum test, you run the vacuum and freeze components for 15 minutes and then note the mTorr (vacuum pressure) number. This is part of the process to identify if your machine has a leak, as explained in our How to Run a Vacuum Test video:

Please ensure you’re following the correct instructions for the specific process you’re performing.
