For anyone watching this (maybe the 3 dentists that won’t just call someone)- always check and change the easiest and least expensive parts first.
I do in my dental office what I do at home for my AC and Heat….. I periodically look through eBay for parts I might eventually need and then buy them.
In this case, a few years ago I got a deal on a full nitrous oxide manifold similar to what I already had installed. It’s a Matrx Centurion II. The unit I bought from eBay had more electronics than my current unit, and auto tank switchover, but for the most part was the same. So it’s been sitting in my basement, just waiting. Because I had the part, when I had an over pressure situation in one of my oxygen lines, I immediately made the assumption that the old manifold was faulty and changed it with my eBay purchase. It was the perfect storm of stupidity because I I had just finished one oxygen tank, and when I opened the second tank the issue started. Because I had only one tank I wasn’t. In the position to test a second o2 tank. If I had, I would have realized Immediately that the regulator attached to the oxygen tank was the issue. Could I have swapped regulators to test? Of course. But troubleshooting wasn’t on my mind. Swapping the manifold out was, so that is what I did.
Enjoy the video if you want to see how to remove and replace a nitrous oxide manifold that’s plumbed in a dental office. At the end of the day I pit back my original Cemturion II without the auto tank changeover. No lock out code, and my staff is used to using it. I’ll keep the newer electronic unit just in case ……
