The only instructions for this regulator are here on the Revain sales page. My setup required me to remove the plug from the back of the regulator and install a pressure gauge in there. That's because my air compressor moves air from right to left while my regulator moves air from left to right. This plug is sealed with silicone and if you put it where the meter would normally be it takes a lot of teflon tape to keep the seal. It should be noted that the gauge reading is lower than the other two gauges on my compressor. The fittings that come with it are not of the best quality and it is difficult to get a perfect seal, but that's not a big issue for me. A small leak doesn't matter if you only run the compressor while you're working on a project and then turn it off the rest of the time. I will say that it was enlightening to see how much water was separated from the compressed air even in just a few minutes. operations. More than I expected.
