“Eaglebeak”Hey Centercut. The instructions that come with these things, advise that the bleed valve is opened before shutting down the power to avoid backlash and stress on the system. Whatever that means. It does appear that the burst disks supplied with these pumps are erring on the side of caution. If I have any trouble with mine, I will be upping the burst strength to at least 5.5 K or maybe 6 K as I assume the standard ones are about 5 K and when filling to 4500 it only takes a small spike to blow them especially after a few cycles of prestressing. 


Well, I’m not sure why they tell you that since the auto shutoff models are exactly the same design except for the auto shutoff function. When they stop they just stop. The operator needs to vent off the system after closing the tank valve. From a mechanical standpoint it doesn’t harm the compressor. Not sure why the instructions say that. The one way fitting is a good idea though. I like that…
